Nano-Materials (3)量子尺寸效应：当粒子的尺寸达到纳米量级时，费米能级附 近的电子能级由连续态分裂成分立能级。当能级间距大于热能、磁 能、静电能、静磁能、光子能或超导态的凝聚能时，会出现纳米材 料的量子效应，从而使其磁、光、声、热、电、超导电性能变化。 量子点(Quantum dots):the band gaps of a quantum dot will change greatly when its diameter is adjusted between 1-10 nm CB As particle gets smaller, the band gap gets bigger.
