Research Phase and Master's Thesis in the M.Sc. Biomedical Engineering and Medical Physics

During the last year of the Master's program Biomedical Engineering and Medical Physics you will have the unique opportunity to work on exciting research topics. During this so-called research phase, you can choose from an extensive number of research groups and current projects.

Research Phase

The build-up of the research phase

To the scope of the one year research phase (60 ECTS) belong firstly, the development of the necessary special knowledge within a cutting-edge research line and secondly, the acquisition of the corresponding experimental or theoretical skills, that are necessary for the realization of the research project within the frame of the Master's thesis. Each of these steps conforms a module, the Master's seminar and the Master's training. Both modules belong intrinsically together and account in total for 30 ECTS. Subsequently, the independent research project can be carried out as part of the Master's thesis, which corresponding module comprises 30 ECTS. The research phase is completed with the Master's colloquium, the defense of the Master's thesis, within this module.

During the research phase, the fulfilment of an independent scientific work is tighly connected with the acquisition of additional skills, such as project management, team work as well as the depiction and presentation of scientific results.

Finding a topic

Students have to take contact by their own with the working groups and potential supervisors, in order to agree on a topic for the research phase/master thesis. Additionally to this, supervisors have the option to announce topics in the section below (supervisors see "Access for supervisors" on the right). However this possibility is not used by all institutes and not all topics are listed. Therefore it is recommended to ask the professors or in the institutes for topics.

Furthermore, it is recommended to start early (at least one semester in advance) to search for an appropriate topic. Having face-to-face interaction with the group, you can see if you like the topic and if you feel comfortable in the group (you will be working one year there!). We discourage you from simple e-mail exchange, as it is usually not successful.

	Electron Spin Qubits in Quantum Dot Molecules - Towards a Quantum Repeater	Finley
	Research group Semiconductor Nanostructures and Quantum Systems Description Quantum communication using single photons provides one route towards physically secure data transmission. However, the total length of today’s quantum key distribution systems is limited to about ~300km due to photon absorption in the “quantum channel” - typically an optical fiber. To overcome this problem, one can build so-called “quantum repeaters” in which the channel is broken down into shorter segments connected by quantum links. In our group we are working towards building a quantum repeater using optically active semiconductor-based quantum dot molecules. We aim to make use of trapped pairs of charges – singlet-triplet (S-T) spin qubits. In the first part of this MSc. project you fabricate a quantum photodiode structure containing coupled quantum dots. This will involve clean-room fabrication, as well as electrical characterization of the fabricated diodes. In the second part, your focus will be on optical characterization of the S-T spin qubits. The goal is to measure exceedingly long coherence times (>>1µs) for special electric fields where the energy gap of the qubit is insensitive to electric and magnetic field fluctuations. Prior knowledge in optics, clean-room fabrication and programming are helpful – but secondary to high motivation and an open and curious mindset to tackle challenging problems. You will get experience in state-of-the-art nanofabrication, optical spectroscopy at cryogenic temperatures, as well as understanding of semiconductors in the context of quantum information and technology.

	Research group Semiconductor Nanostructures and Quantum Systems Description Solid-state qubits are a promising platform for future quantum technology applications. Among them, semiconductor-based quantum dot molecules (QDMs) - two coupled quantum dots – promise unique properties. Long coherence times (>1µs) and strong optical dipole transitions make them ideal candidates for quantum communication purposes. Our group works towards the implementation of a multi qubit-photon interface by optically controlling spin states in QDMs. In your Master's project, you will gain experience in nanofabrication while preparing QDM samples. However, the main part of your time you will spend in an optics lab: Besides studying the fundamental structure of QDMs, you will join in implementing resonance and pulsed excitation to the existing setup. This will enable the investigation and manipulation of charge spins in QDMs at cryogenic temperatures. For successfully participating in the project, prior knowledge in optics and programming is beneficial. Being keen to learn about quantum optics and being able to work in a team is even more important. If you are interested in joining the project and our group, please send your application (including CV and transcript of records) tofrederik.bopp@wsi.tum.de and finley@wsi.tum.de.

Registering the research phase

The registration to all modules belonging to the research phase is done at once in the Dean's Office (Dekanat), normally at the beginning of the third Master's semester. When doing this, the certificate of mentor counseling has to be included. After agreeing on a topic with the future supervisor, students can print out the registration form in the student access.

After six months the Master's thesis should begin. Passing the Master's seminar and the Master's training will be recorded in TUMonline and you are officially alowed to start the thesis.

Handing in the thesis and getting the grade

Before handing in the Master's thesis, you must fill in the final titel of the thesis in the database (student access) and upload an electronic copy (PDF-file). Afterwards, you have to hand in two printed versions in the Dean's Office (Dekanat). You have to hand in the thesis at the latest on the deadline, please keep this on mind.

Extension of the deadline is only possible for good reasons. See FAQ on Thesis extension.

The Master's thesis will be evaluated by the supervisor and a second examiner. The second examiner is appointed by the examination board on suggestion of the supervisor (after official registration of Master’s thesis).

The supervisor and the second examiner will also grade the Master's colloquium, which completes the research phase.

Re-enrollment during the research phase

For any examination you must be enrolled as a student of TUM. Hence you need to re-enroll for one semester more e.g. if you hand in your Master’s thesis or your Master’s colloquium takes place after the current semester ends.

With a due date for your thesis or a scheduled date for the colloquium e.g. in October, you should not forget to re-enroll for the winter semester and the corresponding deadline would be August 15.

Organization of the colloquium

The Master’s colloquium is organised and conducted by the supervisor together with the second examiner. The Master’s colloquium takes approximately 60 minutes, consisting of a 30 minutes talk and 30 minutes examination. Naturally, the inclusion of the colloquium in a group seminar is possible.

Completing your Master studies

At the end of the semester in which you reach the necessary 120 ECTS in your Master's degree program and passed all required exams you will be exmatriculated (according to §13(1) enrolment rules of TUM). In most cases the Master's colloquium will be the last exam to reach this point.

Taking further exams and final documents

You are principally allowed to take further exams after reaching the 120 ECTS, i.e. to replace previous results in the catalog of the focus areas with better results. Therefore it is generally not possible that the final documents are generated before you are exmatriculated. In case you need the final documents (or even preliminary documents) earlier, you have to request for it explicitly. See the Remarks on end of studies and final documents for further information.

Deriving the final grade

The final grade is the ECTS-weighted average of the graded exams.
