Abstract

- We report on the results of our recent theoretical and experimental investigations of a novel, room temperature electrical property of three-terminal ballistic junctions (TBJs). For a symmetric TBJ device, it is found that when finite voltages V-1 and V-r are applied in push-pull fashion, with V-1 = V and V-r = - V. to the left and right branches, the voltage output V-c from the central branch will always be negative. This property is in strong contrast to a symmetric three-terminal device made from conventional diffusive conductors, for which Ohm's law predicts a constant zero output of V-c for all V-1 - V-c.This novel characteristic appears even when the device symmetry is broken, provided that V is greater than the threshold. It is also shown that the TBJ devices show a good parabolic behavior for V-c vs. V in a large range of voltages V.
