4—3 氧化物涂层的电阻 碱土金属氧化物是一种宽禁带的半导体。其内由于带间跃迁出现的电流载流子浓度较低。实际上,全部导电电子都是由施主中心（杂质.晶格缺陷）电离产生的。体积中后者的浓度。处在与决定于阴极热电子活性之晶体表面上缺陷浓度的平衡状态中。这就引起了研究氧化物涂层体积之物理特性的兴趣《电导率、热电动势、霍尔效应等）。来看看所进行工作的主要结果。考虑到氧化物涂层的成份和结构的复杂性,它的电物理特性与活性状态有关系,在叙述多孔系统的数据时,将把它的性质与相应活性状态中单晶体的性质对照。
4-3 Oxide-Coated Resistors The alkaline-earth oxide is a wide-bandgap semiconductor. The current carrier concentration due to the transition between bands is low. In fact, all the conductive electrons are generated by the ionization of the donor center (impurities, lattice defects). The concentration of the latter in the volume. In equilibrium with the concentration of defects on the surface of the crystal, which is determined by the cathode thermal electron activity. This has led to an interest in studying the physical properties of oxide coating volume "conductivity, thermoelectromotive force, Hall effect, etc.). Take a look at the main results of the work carried out. Considering the composition and structure of the oxide coating, its electrophysical properties are related to the active state. When describing the data of a porous system, its properties will be compared with the properties of single crystals in the corresponding active state.
