Content, Learning Outcome and Preconditions
The module focuses on various methods of nanofabrication (optical, electron beam lithography, focused ion beam) and newer emerging techni¬ques (x-ray lithography, nanoimprint, etc.). In particular the physical principles are discussed and limitations for the various methods given. Various synthesis and crystal growth methods for advanced semiconductor nanostructures will be further introduced such as chemical and physical vapor phase epitaxial techniques (MOVPE, MBE, etc.) and the physical growth principles of 0D,1D, and 2D materials highlighted. Examples will be given where these low-dimensional nanostructures are implemented into cutting-edge technological applications. The second part of this lecture deals with specific nanoanalytical methods required for characterization of structural, surface and atomic properties of nanofabricated and synthesized materials. These include electron microscopy, surface analytical methods, ion beam analytical techniques, x-ray techniques, and some new sophisticated techniques, such as atom probe tomography, etc.
After successful completing of the module students are able to:
- to select and evaluate specific nanofabrication methods relevant for nanotechnological applications
- understand the limits of the various methodologies
- understand nanofabrication and analysis of mainly semiconductor-based devices
- perform structural, atomic and interface specific analysis of nanostructured materials
- understand the complex interplay between material synthesis, structural and electronic properties of materials, and their effect on functionalities in cutting-edge device applications

Learning and Teaching Methods
This module consists of a lecture and an exercise class.
In the thematically structured lecture the learning content is presented. With cross references between different topics the universal concepts in nanotechnology and -analytics are shown. In scientific discussions the students are involved to stimulate their analytic-physics intellectual power.
In the exercise the learning content is deepened and exercised via individual lab projects. Thus the students are able to explain and apply the learned methodologies independently.

Description of exams and course work
There will be an oral exam of 25 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using comprehension questions and sample calculations.
For example an assignment in the exam might be:
- Explain different top-down nanofabrication methodologies and their physical limits
- Discuss the thermodynamics and kinetics of crystal phase modes
- Discuss the fundamentals of electron microscopy and element specific analysis, secondary ion mass spectrometry,...
Participation in the exercise classes is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.
The exam may be repeated at the end of the semester.
