Electrical Properties of Some Vacuum Deposited Insulating Films

摘要

Materials can be classified as conductors, semiconductors, or insulators. The distinguishing difference among these classes is the resistivity. Conductors generally have resistivities of the order of 0.00001 ohm-cm; semiconductors fall in a range around 1 ohm-cm; and insulators have resistivities near 10 to the 10th power ohm-cm. This large difference in resistivity of the three classes of materials is the basis of their engineering applications. The resistivities of all three classes may be functions of many parameters, including temperature, purity, conditions of preparation, and the field strengths applied to them. The experimentally determined resistivities for a group of vacuum deposited thin film insulators is presented. (Author)
