810-013872-105 印刷电路板 功率模块

810-013872-105导体是一种具有电导率介于之间的值导体例如铜，以及一种绝缘体，如玻璃。它的电阻率随着温度的升高而下降；金属的行为正好相反。它的引导通过引入杂质(“加添加剂”)变成了晶体结构。当两个不同掺杂的区域存在于同一晶体中时半导体结已创建。的行为电荷载体，其中包括电子,离子，以及电子空穴，在这些连接处是二极管,晶体管，也是现代的电子学。半导体的一些例子是硅,锗,砷化镓，以及元素附近所谓的“非金属楼梯“上了周期表。砷化镓是仅次于硅的第二种常见的半导体，用于激光二极管，太阳能电池微波频率集成电路，以及其他。硅是制造大多数电子电路的关键元素。

半导体器件810-013872-105可以显示一系列不同的有用属性，例如在一个方向上比在另一个方向上更容易通过电流，显示可变电阻，以及对光或热敏感。因为半导体材料的电特性可以通过掺杂和施加电场或光来改变，所以由半导体制成的器件可以用于放大、开关和能量转换。

常见的半导体材料是结晶固体，但是无定形的和液体半导体也是已知的。这些包括氢化非晶硅以及以下物质的混合物砷,硒，以及碲各种比例的。这些化合物与众所周知的半导体一样，具有中等电导率和电导率随温度快速变化的特性负阻。这种无序材料缺乏传统半导体如硅的刚性晶体结构。它们通常用于薄膜不需要较高电子质量的材料，对杂质和辐射损伤相对不敏感的结构。

An 810-013872-105 conductor is a value conductor with an electrical conductivity in between, such as copper, and an insulator, such as glass. Its resistivity decreases with increasing temperature. Metals do the opposite. It is guided by the introduction of impurities (” additives “) into the crystal structure. A semiconductor junction is created when two different doped regions are present in the same crystal. The behavior of charge carriers, which include electrons, ions, and electron holes, at these connections are diodes, transistors, and also modern electronics. Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called “nonmetallic staircase” on the periodic table. Gallium arsenide is the second most common semiconductor after silicon and is used in laser diodes, microwave frequency integrated circuits in solar cells, and others. Silicon is a key element in the manufacture of most electronic circuits.

The semiconductor device 810-013872-105 can display a range of different useful properties, such as passing current more easily in one direction than in another, displaying variable resistance, and being sensitive to light or heat. Because the electrical properties of semiconductor materials can be changed by doping and applying an electric field or light, devices made from semiconductors can be used for amplification, switching, and energy conversion.

Common semiconductor materials are crystalline solids, but amorphous and liquid semiconductors are also known. These include hydrogenated amorphous silicon as well as mixtures of the following substances arsenic, selenium, and tellurium in various proportions. These compounds, like well known semiconductors, have moderate conductivity and a characteristic negative resistance of conductivity that changes rapidly with temperature. This disordered material lacks the rigid crystal structure of traditional semiconductors such as silicon. They are commonly used in structures where thin films do not require high electron mass and are relatively insensitive to impurities and radiation damage.
