介观电子学(Mesoscopic Electronics) 由于半导体微细加工技术的进步,已经能够在低温下观测尺寸量子效应了。在半导体微结构中,如果其尺寸允许电子的弹性散射,但不允许非弹性散射,则在保持电子波相位的状态下发生电子波干涉现象,利用这一现象的新原理电子学即为介观电子学,所谓介观是指介于宏观与微观之间的意思。目前主要是在HEMT结构上,利用聚焦离子束和电子束描绘等方法形成量子点接触,量子线和量子点等结构,用其研究介观现象的。研究热点是阐明量子线中支配电子相位保持时间的机构,目前虽
Mesoscopic Electronics Due to advances in semiconductor microfabrication technology, it has been possible to observe the size quantum effect at low temperatures. In the semiconductor microstructure, if its size allows elastic scattering of electrons but does not allow inelastic scattering, the phenomenon of the interference of the wave of the electric wave occurs while maintaining the phase of the wave of electrons. A new principle utilizing this phenomenon is that the electron is mesoscopic Electronics, so-called mesoscopic refers to the meaning between the macro and micro. At present, mainly in the HEMT structure, the use of focused ion beam and electron beam tracing methods such as the formation of quantum dot contacts, quantum wires and quantum dots and other structures, with its study of mesoscopic phenomena. The research hotspot is to clarify the quantum wire in the control of electronic phase holding time mechanism, although at present
