Abstract
Ultrashort electrical pulses were used to characterize the magnetoplasmon resonance of a two-dimensional electron gas formed in an AlGaAs/GaAs heterostructures at frequencies up to 400 gigahertz. This was accomplished by incorporating the sample into a guided wave probe operating in a dilution refrigerator. A bath temperature of 50mK was recorded during measurements, demonstrating the feasibility of this approach in other situations requiring high magnetic field and mK temperatures.
