What Are The Differences between N-type and P-type Semiconductors?

时间： 2023-07-11 来源：Aurin News

Semiconductor refrigeration chip is widely used in our life. There are many types of semiconductor refrigeration chips in the market. Today we will explain to you the differences between n-type semiconductors and p-type semiconductors.

1. N-type semiconductor

N-type semiconductors, also known as electronic semiconductors, can be formed by doping phosphorus and other impurities into the intrinsic semiconductors.

Because only four valence electrons in a pentavalent impurity atom can form covalent bonds with the valence electrons in the surrounding four semiconductor atoms, the extra valence electrons can easily form free electrons because they are not bound by covalent bonds. In n-type semiconductors, free electrons are the majority of carriers provided by impurity atoms, and holes are minority carriers formed by thermal excitation.

The pentavalent impurity atom that provides free electrons becomes a positive ion due to its positive charge. Therefore, the pentavalent impurity atom is also called donor impurity.

2. P-type semiconductor

P-type semiconductors, also known as hole semiconductors, are formed by doping boron, gallium and indium into intrinsic semiconductors.

When trivalent impurity atoms form covalent bonds with silicon atoms, they lack valence electrons and leave a hole in the covalent bonds. In p-type semiconductors, holes are the majority of carriers formed by doping, while electrons are minority carriers formed by thermal excitation. It is easy for holes to capture electrons and turn impurity atoms into negative ions. Therefore, trivalent impurities are also called receptor impurities.

The above two are for the difference between n-type and p-type semiconductors.

【技术】一文掌握半导体制冷片四种常见的参数

半导体制冷片被称为温差电致冷组件，又因帕尔贴原理被称作帕尔贴。制冷片本身并无制冷效果，其原理为把热量从冷面传输到热面，再由热面的散热设备散发出热量，是一种专门用来传送热量的工具。为了更方便大家选择合适的产品，本文由澳凌来介绍一下制冷片四种常见的参数。

【技术】一文了解半导体致冷片

本文澳凌将为你详细介绍半导体致冷片。半导体致冷片，起初是由前苏联缓建我国军事项目发展开来的，它的真正的名字叫半导体致冷片，而非半导体制冷片，因其“致”与“制”同音，因大部分人习惯叫作制冷片。主要作用目前有致冷和致热（使用电时），发电（温差时）
