Broadband Terahertz Time-domain Spectroscopy of Quantum Materials in a Dilution Refrigerator
Abstract
We have constructed a terahertz time domain spectroscopy system using a Bluefors dilution refrigerator with a 7 T split-coil magnet. Using a gallium arsenide single quantum well sample, terahertz waveforms were measured at 145 mK in a magnetic field range from 0 to 6 Tesla to measure cyclotron resonance. Effective mass is found to be 0.073 me, which is larger than the commonly accepted bulk value of 0.068 me.
