Abstract
Nb, NbN, and Nb3Ge nanobridges on sapphire substrates with hysteretic I–V-characteristics are used as active elements in relaxation oscillators. Amplitudes of up to 350 mV and frequencies of up to 500 MHz could be generated, which make these oscillators useful for many applications. Linewidth and amplitude of the relaxation oscillations in dependence of nanobridge geometry are studied in some detail.
