Abstract

A picosecond time-resolved ballistic electron transport was measured in a two-dimensional electron gas (2DEG) transverse magnetic focusing device. electrons was injected through the emitter point contact using picosecond electrical pulses and their arrival at the collector was resolved optoelectronically. It was observed that the transport time of the electrons was 52 ps which was nearly twice as long as the expected time of flight for ballistic electrons traveling at fermi velocity. The results show that the response width of the ballistic electrons signal is approximately 35 ps.
