N型半导体 - 百度百科
N型半导体即 自由电子 浓度 远大于 空穴 浓度的 杂质半导体。 半导体是一种导电能力介于导体和 绝缘体 之间的物质，其按照载流子（或 晶体缺陷）的不同可分为P型半导体和N型半导体，半导体的导电性能与载流子（晶体缺陷）的密度有很大关系 [3]。 半导体中有两种 载流子，即 价带 中的空穴和 导带 中的电子，以 电子导电 为主的半导体称之为N型半导体，与之相对的，以 空穴导电 为主的半导体称为 P型半导体。 “N”表示 负电 的意思，取自英文Negative的第一个字母。 在这 …
What is an N-type Semiconductor? - WatElectronics.com
2019年3月28日 · A N-type semiconductor is defined as a type of extrinsic semiconductor doped with a pentavalent impurity element which has five electrons in its valence shell. The pentavalent impurity or dopant elements are added in the N-type semiconductor to increase the number of electrons for conduction.

p-n junction diodes are made up of two adjacent pieces of p-type and n-type semiconducting materials. p-type and n-type materials are simply semiconductors, such as silicon (Si) or germanium (Ge), with atomic impurities; the type of impurity …
N-Type Semiconductor - an overview | ScienceDirect Topics
An N-type semiconductor is defined as a type of semiconductor created by doping an intrinsic semiconductor with an electron donor element, such as phosphorus or arsenic. In N-type semiconductors, electrons are the majority carriers, while holes are the minority carriers.
N-type semiconductors are a type of extrinsic semiconductor where the dopant atoms are capable of providing extra conduction electrons to the host material (e.g. phosphorus in silicon). This creates an excess of negative (n-type) electron charge carriers.
