Optical, electronical and mechanical properties of silicon at low temperatures

Type: Poster
Session: Poster session


Silicon is a candidate material for future gravitational wave detectors being operated at cryogenic temperatures. Operating silicon in the near infrared might be a solution for low noise operation. However, several optical properties of silicon are not known in the near infrared and at cryogenic temperatures. We present current results on the investigation of optical, electronical as well as mechanical properties in a wide temperature range. Amongst them are carrier densities, optical absorption, the mechanical loss and its correlation to defects as well as the stress induced birefringence. The results as well as their implication to modern gravitational wave detectors are presented.
