The electron cut-off wavelength transistor

We propose a transistor based on the transverse quantization of electron waves. The spread of non-degenerate electrons is some 20 nm at room temperature. In a wire-like structure having a diameter of this or smaller size, the electron transport will be cut-off like that of electromagnetic modes in a wave guide. Accelerated in electric fields, hot electrons have smaller spread and may now propagate through the narrow electron waveguide. This principle presents the basis for novel minuscule and versatile simple devices.
