Nanosystems

Semiconducting nanodevices. Nanofrabrication. Spray coating techniques. Film functionalization. CMOS-based nanosystems. Hybrid systems. Autonomous systems. Sensors (gas, temperature, gas, bio). Energy harvesting. Through the Projektpraktikum,the students will work on a special nano-project. Design, fabrication and characterization of autonomous sensors network based on carbon nanotubes and graphene films.

After successful completion of the module, students have acquired basic understanding of nanotechnology system as well as practical knowledge for instance about characterizations of nanoparticles that are used as active and/or electrode materials in sensors and other devices. They know how to measure the performance of different types of nanoelectronic devices and systems. At the end of the module the students are able to analyze and evaluate nanotechnology systems. They know how to present the results of their experiments in form of a scientific presentation and have learnt how to organize and present their work.

Basic Physical concepts, materials, electronic devices, fundamentals of Nanoelectronics The student should have taken classes in
- Nanoelectronics
- Nanotechnology

The theoretical background to understand the operation of nanosystems will be provided in the lectures with traditional methods (power point presentations, discussion). Half of the course will be carried out in the laboratories. Small groups will work in a coordinated fashion towards the design, realization and characterization of different carbon-based devices.

The following types of media will used:
- Presentation slides
- Lecture script
- Black board

Recommended literature:
- K. Goser and P. Lugli, "Nanoelectronics and nanosystems" Springer Verlag - Additional reading material, class notes and useful web sources will be provided to the students by a sharepoint system

The examination consists of three parts: The first part, covering the 2 hours lectures/week will be examined by a written test by the middle of the semester. The test will consist of several questions where the students have to prove knowledge related competencies. This part will count for 50% of the final grade. In the second part each student will participate in one simulation activity (in groups of 2 people) or in a literature review (alone), that will start at the beginning of the semester and will have to be finished by the middle of the semester. An oral presentation will conclude this part, which will count for 20% of the final grade. By the simulation and literature review part the student will learn to analyze and critically evaluate systems related to energy applications in the field of nanotechnology. In the third part each student will participate in one experimental activity (in groups of 4 people) that will start at the middle of the semester and will have to be finished by the end of lecturing period. A group oral presentation will conclude this part, which will count for 30% of the final grade. By attending the experimental part of the module, the students will learn to apply and to create own systems and present their gained results in a scientific form.
