The objective of this practical course is to train practical experimental skills that are needed in an interdisciplinary research laboratory environment in the field of nanotechnology. It includes skills needed for the fabrication of nanostructures by means of top-down as well bottom-up techniques and the characterization of nanostructures with various techniques.

This course will provide hands-on training in nanofabrication as well as characterization of realized nanostructures in the NanoLab cleanroom as well as at a number of research group labs.
Cleanroom experiments
Students will work in pairs and each group performs 3 nanolithography experiments (each experiment lasts 1 day in the cleanroom), which are listed in Table 2. The cleanroom experiments start with an introductory lecture on the fundamentals of three nanolithography techniques, i.e. electron-beam lithography (EBL), 3D lithography based on 2-photon polymerization (2PP) and displacement Talbot lithography (DTL). Subsequently, by means of these lithography techniques nanometer-sized features will be fabricated and inspected in the NanoLab cleanroom.
The cleanroom experiments are listed in the following table:

Research group experiments
Students will work in groups of 2 and each group will do 2 experiments. The two experiments one group is doing cannot be within the same category of materials: molecular or soft-matter versus solid-state.
