W. Poirier et al., Tunneling and interferences in very small GaAs metal-semiconductor field-effect transistors, PHYS REV B, 59(16), 1999, pp. 10856-10863
We study the transport through gated GaAs:Si wins of 0.5 mu m length in the
insulating regime and observe transport via tunneling at very low temperat
ure. We describe the mean positive magnetoconductance and the mesoscopic fl
uctuations of the conductance (versus energy or magnetic field) purely with
in one-elctctron interference model. [S0163-1829(99)10615-5].
