Summary, in English

A technology was developed to embed nm-sized metallic features in close vicinity to semiconductor heterostructures, which allows a direct integration of resonant tunneling diodes (RTD) inside the channel of permeable base transistor. A AlGaAs/InGaAs based RTD was grown by molecular beam epitaxy (MBE), with peak current density either 70 or 120 kA/cm<sup>2</sup>. A fundamental oscillation frequency of 800 MHz was detected, with higher harmonics up to 2.6 GHz, using a spectrum analyzer. It was found that the oscillations could be quenched by applying a large (-1.5V) negative gate bias. The results indicate that a three terminal resonant tunneling transistor can be used to obtain pulsed operation of a resonant tunneling based oscillator.
