The I-V Characteristics of Double-Barrier Stair-Wells
We investigated the I-V characteristics of the double barrier stair-well structure. Resonant tunneling current is achieved by application of an electric field, which increases the transmission under positive bias and decreases it under the reverse bias. This asymmetry can be used for rectification and the device works as a quantum diode. Furthermore, the same structure can perform, under negative bias, resonant tunneling processes with different characteristics.
