DURIP CRYOGEN-FREE OPTICAL CRYOSTAT FOR LOW TEMPEATURE OPTICAL SPECTROSCOPY OF VAN DER WAALS HETEROSTRUCTURE IN A CONFOCAL MICROSCOPE SETUP
Abstract
To utilize the full potential of transition-metal-dichalchogenides-based,2-D heterostructures and investigate the unique physics, the control of the temperature down to a base temperature of 4.2 K is a necessity. Low-temperature electrical transport measurement can reveal the scattering mechanism and fundamental limit of the mobility, identify insulator-to-metal transition, and unveil possible emerging high-temperature superconductivity. Low-temperature optical spectroscopy is also of vital importance, with the capability of revealing the unique excitonic physics and light-matter interaction in 2-D heterostructures.
