摘要：

The frequency of current self-oscillations in weakly coupled superlattices usually varies continuously with increasing applied voltage within a single plateau of the I-V characteristics. However, a more detailed investigation reveals the existence of discrete frequencies, which are locked to particular values. The locking frequency is an integer multiple of a fundamental frequency f(0), which is determined by the length of the used coaxial cables.
