Semiconductor Basics: Crystals
The behavior of electrons and holes is fundamental to understanding how semiconductor devices work. In an intrinsic semiconductor, thermal energy can cause valence electrons to jump to the conduction band, leaving behind a “hole” that can be filled by another electron. This creates thermally-induced electron movement and an equal number of holes moving in the opposite direction.
Semiconductor Basics: Atomic Structure
In chemistry, the structure of an atom is crucial in understanding how it behaves and interacts with other atoms. The basic structure of an atom consists of a central nucleus made up of protons and neutrons, surrounded by a cloud of electrons in various energy levels or shells. In this cloud, electrons move in specific regions called orbitals.
