Abstract
1,130,657. Gunn effect oscillators. TELE. FUNKEN PATENTVERWERTUNGS G.m.b.H. 28 Oct., 1966 [10 Nov., 1965], No. 48546/66. Heading H3T. [Also in Division H1] A Gunn effect oscillator element is subjected to a variable applied magnetic field to vary the frequency and amplitude of the oscillations. Means may also be provided for varying the ambient temperature of the element to modify the oscillations in a similar manner. It is stated that the effect of the magnetic field is particularly pronounced at low temperatures and in III-V semi-conductors.
