In semiconductors, a light hole and a heavy hole refer to different energy states that are created in the valence band. Light holes have lower effective mass and higher mobility, while heavy holes have higher effective mass and lower mobility. These terms are important in understanding the electronic band structure of semiconductors and their properties.

What is a light hole?
A light hole is a term used in physics to describe the higher energy band in a semiconductor material where electrons are not typically found. It is a type of electronic band structure that occurs in materials like semiconductors when electrons are excited to higher energy levels. Light holes have properties that are important for understanding the behavior of electrons in these materials.
What is heavy hole light hole and split-off hole?
the occupied highest band is the heavy band, the band prior below it is ligh band, the distance between two extremal points of those band is split-off band. At those points, hole is situated to be corresponding holes.
What is recombination and lifetime?
Recombination is the process by which electrons and holes combine in a semiconductor to generate light or heat. It plays a crucial role in determining the efficiency of devices such as solar cells and LEDs. Lifetime refers to the average time an electron or hole remains in the semiconductor before recombining; a longer lifetime indicates better efficiency in devices.
What conducts electricity when exposed to light so it is used in solar cells and in light meters?
Semiconductor materials such as silicon conduct electricity when exposed to light and are commonly used in solar cells and light meters. When photons from light hit the semiconductor, they generate free electrons and holes, allowing for the flow of electricity.
How does light calculate in a black hole?
I am not aware of light calculating anything in a black hole.
What is the difference between heavy hole and light hole in semiconductor physics?
In semiconductor physics, heavy holes and light holes are types of charge carriers with different effective masses. Heavy holes have a larger effective mass and move more slowly than light holes in a semiconductor material. This difference in mobility affects the electronic properties of the material, such as conductivity and energy levels.
What is the term for a semiconductor that is missing electrons?
p-type semiconductor A semiconductor that is missing electrons is called an electron hole.
What is the the term for a semiconductor that is missing electrons?
p-type semiconductor A semiconductor that is missing electrons is called an electron hole.
What is the term for a semiconductor that is missing electronic?

What is a bound hole electron pair in a semiconductor?
exciton
Why p type semiconductor has majority charge carrier as hole?
The majority carrier in p-type semiconductor is the hole. Electron carriers in p-type semiconductor are minority carriers. Minority carriers in any semiconductor are produced mainly by heat. Only at absolute zero temperature would there be no minority carriers.
What is an area of space with gravity so strong that it traps light?
A black hole has gravity so heavy it traps light.
What are the properties and characteristics of light holes in semiconductor materials?
Light holes in semiconductor materials are a type of charge carrier with lower effective mass and energy compared to heavy holes. They have a higher mobility and can contribute to the electrical conductivity of the material. Light holes are important in the band structure of semiconductors and play a role in optical and electronic properties.
When an electron is displaced in a semiconductor the hole thats left behind is what?
When an electron is displaced in a semiconductor, the hole that is left behind is called an electron hole. Energy can still be conducted because other electrons can and do jump to the space left by a displaced electron.
When an electron is displaced in a semiconductor the hole that left behind is?
A lack of electron
