什么是半导体材料物质存在的形式多种多样,有固体、液体、气体等.我们通常把导电性和导热性差或不好的材料,如金刚石、人工晶体、琥珀、陶瓷等,称为绝缘体;而把导电、导热都比较好的金属,如金、银、铜、铁、锡、铝等称为导体.可以简单地把介于导体和绝缘体之间的材料称为半导体.与导体和绝缘体相比,半导体材料的发现是最晚的,直到20世纪30年代,当材料的提纯技术改进以后,半导体的存在才真正被学术界认可.
What is a semiconductor material There are many forms of material existence, solid, liquid, gas, etc. We usually called poor or poor conductivity and thermal conductivity of materials such as diamond, artificial crystals, amber, ceramics, The conductivity, heat conduction is better than the metal, such as gold, silver, copper, iron, tin, aluminum, etc. can simply be between the conductor and the insulator material is called semiconductor.Compared with the conductor and the insulator , The discovery of semiconductor materials is the latest, until the 1930s, when the material purification technology improved, the existence of the semiconductor really recognized by academics.
