一般,降低一个物体的维度,会使它的量子性质更明显.例如,局限于半导体二维平面、一线线、零维斑点上的电子,其允许的能量受到严格的限制,更加表露出电子在低维运动中的能量量子化特征.用半导体或金属都可产生零维量子斑,其量子效应能用来制作高度可控的量子器件.Cornall In general, reducing the dimension of an object will make its quantum properties more obvious.For example, confined to two-dimensional semiconductor surface, first-line, zero-dimensional spots on the electron, the allowable energy is strictly limited, more revealing the electron in Quantum characteristics of energy in low-dimensional motion. The use of semiconductors or metals can produce zero-dimensional quantum dots, the quantum effect can be used to make highly controlled quantum devices.Cornall
