Êǵġ£gold quantum point contacts (QPCS)£º½ð²ÄÁÏ×ö³ÉµÄÁ¿×Óµã½Ó´¥¡£ ¸ÅÄ Quantum Point Contact (QPC) is a narrow constriction between two wide electrically-conducting regions, of a width comparable to the electronic wave length (nano- to micrometer). Quantum point contacts were first reported in 1988 by a Dutch group (Van Wees et al.) and, independently, by a British group (Wharam et al.). Çë²ÎÔÄElectronic Transport in Mesoscopic Systems, S.
