Temperature-Variable Characteristics and Noise in Metal - Semiconductor Junctions

Although metal-semiconductor junctions were first explored a hundred years ago, some important aspects of the transport mechanism of electrons across the metal-semiconductor barrier have not yet been fully explained. In this paper, we report on a new model and supporting experimental results which explain deviations observed from the ideal exponential current-voltage characteristic. The model and results are applicable to the optimization of microwave and millimeter-wave front ends.
