| 中文摘要 | by using a transfer-matrix method on the basis of two-dimensional (2d) bloch sums in accordance with a tight-binding scheme, a self-consistent calculation on the resonant tunneling in asymmetric double-barrier structures is presented, in which contributions to resonant tunneling from both three-dimensional (3d) electrons in the contacts and 2d electrons in the spacer or accumulation layers are considered simultaneously. the charge buildup effect on the current versus voltage (i-v) curves is evaluated systematically, showing quantitatively how it results in the i-v bistability and enhanced differences between i-v curves for positive and negative bias in an asymmetric double-barrier structure. special attention is focused on the interaction between 3d-2d and 2d-2d resonant-tunneling processes, including the suppression of 2d-2d resonant tunneling by the charge buildup in the well accompanying the 3d-2d resonant tunneling. the effects of the emitter doping condition (doping concentration, spacer thickness) on the presence of two types of quasi-2d levels in the emitter accumulation layers, and on the formation of a potential bulge in the emitter region, are discussed in detail in relation to the tunneling process. |
