Fabrication and characterization of THz metasurfaces
You will use state of the art cleanroom microfabrication techniques and 3D printing for the develop-ment of THz devices such as Thz filters.
Keywords: THz, microfabrication, 3D printing, thin films, devices.
The THz regime is the bridge between optics and electronics. However, there is still a lack of materials and devices for this spectrum area. The project aims at developing THz metamaterials. You will use and optimize the technology of our lab based on thin polymer films. In addition, you will use COMSOL Mul-tiphysics for the simulations of the devices and work on the characterization of the metasurfaces with state-of-the-art equipment (figure 1 (a&b).
We are looking for a motivated student with a physics, material science, electrical engineering, or chemistry background for an MSc thesis in the Transport at Nanoscale Interfaces Laboratory at Empa.
During the project, the MSc student will work on:
- The development of thin film devices using TOPAS
- Cleanroom fabrication of metasurfaces
- COMSOL Multiphysics simulations using Radio Frequency module
- THz time-domain spectroscopy for the characterization of the devices
- Matlab/python for analyzing data
