Ultrasensitive and Wide-Bandwidth Thermal Measurements of Graphene at Low Temperatures
At low temperatures, the electron gas of graphene is expected to show both very weak coupling to thermal baths and rapid thermalization, properties which are desirable for use as a sensitive bolometer. We demonstrate an ultrasensitive, wide-bandwidth measurement scheme based on Johnson noise to prob...
