• Propagation of surface charge waves in a MOS structure is theoretically predicted and experimentally observed. A magnetic field is applied parallel to the MOS layer and perpendicular to the wave propagation direction. For a given magnetic field, it was shown that the wave can propagation direction. For a given magnetic field, it was shown that the wave can propagate only in one direction. A very large non-reciprocity in the wave propagation was also experimentally observed using n-InSb at 77°K. For example, the transmission voltage was attenuated b 3.5 db in one direction (forward direction), and by 40 db in the opposite direction (backward direction) at a frequency of 1 MHz for the sample used. The forward transmission gradually decreased with increasing frequency and was observed up to 480 MHz. Using the observed values of the wavelength, the phase velocity was calculated to be about 4×10^7 cm/sec. The phase velocity is expected to be reduced further by increasing the MOS capacitance. Most of the observations agreed with the theory.
