| Abstract: Topological insulators can be utilized in a new type of infrared
photodetector that is intrinsically sensitive to the polarization of
incident light and static magnetic fields. The detector isolates single
topological insulator surfaces and allows light collection and exposure
to static magnetic fields. The wavelength range of interest is between
750 nm and about 100 microns. This detector eliminates the need for
external polarization selective optics. Polarization sensitive infrared
photodetectors are useful for optoelectronics applications, such as light
detection in environments with low visibility in the visible wavelength
regime. |
