P Type and N Type Semiconductor: Doping : Pure semiconductor material is known as intrinsic material. Before intrinsic material can be used for device manufacture, impurity atoms must be added to improve its conductivity. The process of adding the atoms is termed doping. Two different types of doping are possible; donor doping, and acceptor doping. […]

Conductor Semiconductor and Insulator: Bonding Forces Between Atoms: Whether a material is a Conductor Semiconductor and Insulator depends largely upon what happens to the outer-shell electrons when the atoms bond themselves together to form a solid. In the case of copper, the easily detached valence electrons are given up by the atoms. As illustrated in

Conduction in Solids: Conduction in Solids or any given material occurs when an applied voltage causes electrons within the material to move in a desired direction. This may be due to one or both of two processes; Electron Motion and Hole Transfer. In electron motion, free electrons in the Conduction band are moved under the

Introduction to Semiconductor Materials and Devices: An electronic device controls the movement of electrons. The study of electronic devices requires a basic understanding of the relationship between electrons and the other components of an atom. The movement of electrons within a solid, and the bonding forces between atoms can then be investigated. This leads to
