Abstract

We have observed multiple oscillations in a planar Gunn diode fabricated using an AlGaAs/GaAs based quantum well structure. The material used was grown by molecular beam epitaxy and devices were made using electron beam lithography. The devices had a 4 mu m cathode-anode distance and 60 mu m width. They showed multiple oscillations at 29GHz, 33GHz and 35GHz. This is the first observation of multiple frequencies in a planar quantum well structure device and may have applications as a single chip multi-frequency source.
