| 中文摘要 | with contributions from both three-dimensional (3d) electrons in heavily doped contacts and 2d electrons in the accumulation layer, a self-consistent calculation based on effective mass theory is presented for studying the anomalous behaviour of the quasi-bound levels in the accumulation layer and that in the central well of an asymmetric double barrier structure (dbs). by choosing the thickness of the incident barrier properly, it is revealed that these two quasi-bound levels may merge into a unique bound level in the off-resonance regime which shows a very good 2d nature in contrast to the conventional picture for level crossing. an evident intrinsic i-v bistability is also shown. it is noticeable that the effect of charge build-up in the central well is so strong that the electric field in the incident barrier even decreases when the applied bias increases within the resonant region. |
