Vs. Tsoi, On the question of short-period oscillations of the collector voltage during transverse electron focusing, JETP LETTER, 68(12), 1998, pp. 935-941
Giant short-period oscillations during transverse electron focusing at high
emitter voltages have been observed in bismuth samples with a superlattice
on the surface. A model is proposed which explains the onset of the oscill
ations, their position on the magnetic-field scale, and their intensificati
on and shift along the magnetic-field scale with increasing current (this s
hift depending on the direction of current flow) and which can also account
for the absence of oscillations in fields which are multiples of the field
of the first oscillation. In this model the oscillations are attributed to
the appearance of resonant surface (edge) states and their contribution to
the electron transport. (C) 1998 American Institute of Physics. [S0021-364
