In physics, chemistry, and electronic engineering, an electron hole (often simply called a hole) is a quasiparticle denoting the lack of an electron at a position where one could exist in an atom or atomic lattice.

The electron is moving in the opposite direction of the positive hole. As the hole moves farther to the right, electrons must move left to accommodate the hole. The hole in the absence of an electron in the valence band due to P-type doping. It has a localized positive charge.

Electrons and holes are two fundamental concepts in semiconductor physics. Electrons are negatively charged particles that carry current in a material, while holes are essentially the absence of an electron and are considered positively charged.

Electrons and Holes in Semiconductors CHAPTER OBJECTIVES This chapter provides the basic concepts and terminology for understanding semiconductors. Of particular importance are the concepts of energy band, the two kinds of electrical charge carriers called electrons and holes, and how the carrier

2011年10月15日 · Electron holes are like spaces that the electrons can jump to, or move through. When we talk about electron holes moving, it's like how the available space moves in a game of Chinese checkers. $\endgroup$

Holes are formed when electrons in atoms move out of the valence band (the outermost shell of the atom that is completely filled with electrons) into the conduction band (the area in an atom where electrons can escape easily), which happens everywhere in a semiconductor.
