Cryogenic Temperature Nanoscopic Voltage Profiling of Operating Laser Devices


Keywords: , , ,

A nanoscopic probing technique to measure voltage drop across an operating device in cryogenic temperature condition has been developed and established. The cross section surface of the terahertz (THz) quantum cascade laser (QCL) was profiled to resolve the voltage variation.
