A 40-NM-PITCH DOUBLE-SLIT EXPERIMENT OF HOT-ELECTRONS IN A SEMICONDUCTOR UNDER A MAGNETIC-FIELD

We report a double-slit experiment of hot electrons in a semiconductor under a magnetic field, The pitch of the double slit buried in the se miconductor is 40 nm and the electron energy is of the order of 100 me V. By applying a magnetic field, the change in current that passes thr ough the slits is observed at the segmented collector. The measured cu rrent shows a clear minimum around B=0 T, with this behavior agreeing with a theoretical calculation based on double-slit interference. Quan titative estimation is consistent with this order of current variation . We think that these results show evidence of the observation of hot electron interference by a double slit in a semiconductor (C) 1997 Ame rican Institute of Physics.
