Abstract

1,205,211. Transferred electron oscillators. NATIONAL RESEARCH DEVELOPMENT CORP. 6 Oct., 1967 [21 July, 1966], No. 32773/66. Heading H1K. A transferred electron oscillator comprises a piece of suitable material, e.g. gallium arsenide, having two electrodes to serve as anode and cathode and a third electrode for producing a depletion layer in the neighbourhood of the first two electrodes, the third electrode being reversebiased relative to the first two and means being provided to vary the reverse bias and thereby alter the current path between the anode and cathode so that the frequency of the oscillations is changed. In a first embodiment the first two electrodes are in the form of parallel metallic or diffused n<SP>+</SP> strips in one face of the material and the third electrode is a diffused or alloyed p-type region lying between the other two, whilst in a second embodiment the first two electrodes diverge and the third electrode is disposed across the closer pair of ends of the first two. In a third embodiment the material is an epitaxial n-type layer on a p-type substrate which also acts as the third electrode, and in a fourth embodiment the material is deposited on an n+ -type substrate which acts as the anode. The cathode is a metallic or diffused n<SP>+</SP> region in the surface of the material opposite the anode and the third electrode is an annular p-type region surrounding the cathode.
