# How do holes carry charge?

In an applied electric field, the electrons move in one direction, corresponding to the hole moving in the other. If a hole associates itself with a neutral atom, that atom loses an electron and becomes positive. Therefore, the hole is taken to have positive charge of +e, precisely the opposite of the electron charge.

## What is a hole in physics?

hole, in condensed-matter physics, the name given to a missing electron in certain solids, especially semiconductors. Holes affect the electrical, optical, and thermal properties of the solid.

What is hole in physical chemistry?

Holes and electrons are the two types of charge carriers responsible for current in semiconductor materials. A hole is the absence of an electron in a particular place in an atom. Although it is not a physical particle in the same sense as an electron, a hole can be passed from atom to atom in a semiconductor material.

### What is electron hole theory?

A hole can be seen as the “opposite” of an electron. Unlike an electron which has a negative charge, holes have a positive charge that is equal in magnitude but opposite in polarity to the charge an electron has.

### Do holes have mass?

Actually holes are simply absence of electrons, note that its the electrons which flow and not the holes, due to the motion of electrons the holes appear to be moving, so thats why holes have the same mass as an electron.

What is the hole class 12th physics?

A hole is an absence of an electron in a particular place in an atom. Although it is not a physical particle in the same sense as an electron, a hole can be passed from atom to atom in a semiconductor material. Electrons and holes, both, are the charge carriers in any semiconductor substance.

#### What is a hole in physics class 12?

In other words, a hole is an absence of an electron in a particular place in an atom. Hole is not a physical particle in the same sense as an electron, but a hole can be passed from atom to atom in a semiconductor material.

What is hole in pn junction?

The open circles on the left side of the junction above represent “holes” or deficiencies of electrons in the lattice which can act like positive charge carriers. The solid circles on the right of the junction represent the available electrons from the n-type dopant.

## Why is a hole heavier than electron?

Based on the relation E = mc^2 , Energy of hole is greater than that of electron, thus holes have mass greater than that of electrons.

## What is a hole and what is its physical significance?

A hole is the absence of an electron in a particular place in an atom. Although it is not physical particle inthe same sense as an electron ,a hole can be passed from atom in a semiconductor material. Electrons orbit the nucleus as defined energy levels called bands or shells.

What is positive hole?

A positive hole in a semiconductor is a vacancy which is created at the site of a covalent bond when an electron leaves a covalent bond.
