Abstract
Metal-semiconductor-metal photodiodes were optimized as pulse generators for time-resolved electrical measurements at low temperatures and high magnetic fields, using a laser diode as the light source. For the photoconductor, a heterostructure consisting of high-quality GaAs and low-temperature grown GaAs was used. The dependence of the photocurrent pulses on the applied magnetic field was determined. A two-dimensional electron gas in a magnetic field served as the device under test for the time-resolved measurements. We observed a splitting of the incident pulse into two transmitted pulses resulting from modal dispersion in the two-dimensional electron gas.
