Quadratic field effect in quantum-well films
Idlis B. G. , Frolov V. D.
The quadratic field effect in a quantum-well film between two electrodes is analyzed. A charge double layer arises in the film near the edges of the electrodes because of the electric field. Estimates show that the height of the field-induced potential barrier in films made from several narrow-gap semiconductors may exceed the thermal potential at room temperature.
