Abstract
We report the first observation of the resonant tunneling features associated with the quantized levels in the accumulation layer of the double-barrier resonant tunneling structure (DBRTS) with undoped electrodes. This quantum effect causes additional kinks in the current-voltage (I-V) characteristic and an increasingly enhanced oscillation behavior in the differential conductance-voltage (G-V) curve. Three discrete quantum levels have been observed based on the room-temperature G-V curve. Our measurements are made without the presence of magnetic field and thus the experimental results are totally different from the magneto-oscillation.
