Because of the existence of the superconducting gap, the normal photon-assisted tunneling process become more complicated, leading to many variations of the current between positive and negative values in I vs gate voltage Vg curve.

在正常-量子点-正常体系中，所有的 PAT 峰都为正峰，间距为 hn 。⑶由于超导能隙的存在，正常的光子协助隧穿过程将更为复杂，使得电流-栅压的关系出现多次在正负之间的变化。

The organic molecules with it-conjugated structure are ideal structural units for molecular wires. The asymmetric electronic structure of the molecular junctions is the basic reason for molecular rectification. Rotaxanes and catenanes are ideal structural units for molecular switches. The operation principle of molecular field effect transistors is quantum tunneling, the metal/insulator/mental tunneling is mainly.

具有π-共轭结构的有机分子体系是构造分子导线的理想单元；分子结的电子结构不对称性是分子具有整流特性的根本原因；轮烷和索烃是构造分子开关的理想单元之一；分子场效应晶体管的工作原理是量子隧穿，主要是金属－绝缘体－金属间的隧穿效应。

The poor endurance is ascribed to the poor quality of TEOS used for the tunneling oxide as well as the horn-shaped channel. The traps are easily generated because of poor quality of TEOS. Besides, high electric field due to the horn of the channel could seriously damage the tunneling oxide.

耐久性差的主要原因，是因为使用TEOS当作穿隧氧化层，而TEOS的品质较乾氧化层差，容易产生缺陷；再加上因为通道尖角造成的局部大电场会对穿隧氧化层造成极大的伤害，所以特性并不理想。
