Negative conductivity in semiconductors due to transfer of hot electrons in geometric space
Abstract
A nonlinear steadystate theory demonstrates the existence of negative differential conductivities that are due to interaction of two thin currentcarrying semiconducting sheets. In the one sheet highly mobile electrons are heated by the electric field and diffuse into the second sheet, where mobility is low and consequently the electrons are cooled and decelerated. An efficient interaction is obtained only for sheet thicknesses in the order of magnitude of the Debye distance or below. Several characteristics calculated for silicon show the expected effect rather clearly.
