半导体

三种导电性不同的材料比较,金属的价电带与导电带之间没有距离,因此电子(红色实心圆圈)可以自由移动。绝缘体的能隙宽度最大,电子难以从价电带跃迁至导电带。半导体的能隙在两者之间,电子较容易跃迁至导电带中。
半导体和绝缘体之间的差异主要来自两者的能带间隙(Bandgap)宽度不同

半导体(Semiconductor)是指一种导电性可受控制,范围可从绝缘体至导体之间的材料。无论从科技或是经济发展的角度来看,半导体的重要性都是非常巨大的。今日大部分的电子产品,如计算机、移动电话或是数字录音机当中的核心单元都和半导体有着极为密切的关连。常见的半导体材料有硅、锗、砷化镓等,而硅更是各种半导体材料中,在商业应用上最具有影响力的一种。

材料的导电性是由导带中含有的电子数量决定。当电子从价带获得能量而跳跃至导电带时,电子就可以在带间任意移动而导电。一般常见的金属材料其导电带与价电带之间的能隙非常小,在室温下电子很容易获得能量而跳跃至导电带而导电,而绝缘材料则因为能隙很大(通常大于9电子伏特),电子很难跳跃至导电带,所以无法导电。

Semiconductor 半导体

Silicon crystals are the most common semiconducting materials used in microelectronics and photovoltaics.
Filling of the electronic states in various types of materials at equilibrium. Here, height is energy while width is the density of available states for a certain energy in the material listed. The shade follows the Fermi–Dirac distribution (black=all states filled, white=no state filled). In metals and semimetals the Fermi level EF lies inside at least one band.
In insulators and semiconductors the Fermi level is inside a band gap; however, in semiconductors the bands are near enough to the Fermi level to be thermally populated with electrons or holes.

Semiconductors are crystalline or amorphous solids with distinct electrical characteristics. They are of high resistance - higher than typical resistance materials, but still of much lower resistance than insulators. Their resistance decreases as their temperature increases, which is behavior opposite to that of a metal. Finally, their conducting properties may be altered in useful ways by the deliberate introduction of impurities ("doping") into the crystal structure, which lowers its resistance but also permits the creation of semiconductor junctions between differently-doped regions of the extrinsic semiconductor crystal. The behavior of charge carriers at these junctions is the basis of diodes, transistors and all modern electronics.
