What is the significance of the effective mass of holes in silicon for electronic device performance?
The effective mass of holes in silicon is important for electronic device performance because it affects the mobility of charge carriers in the material. Higher effective mass can lead to lower mobility, which can impact the speed and efficiency of electronic devices. Therefore, understanding and controlling the effective mass of holes in silicon is crucial for optimizing the performance of electronic devices.
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 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.
Are black holes infinite in size and mass?
No, black holes are not infinite in size and mass. They have a finite size and mass, but their density is extremely high, leading to their strong gravitational pull.
What is the effective mass of spring?
The effective mass of a spring is the mass that would behave the same way as the spring when subjected to a force or acceleration. It is a concept used in physics to simplify calculations in systems involving springs. The effective mass of a spring depends on its stiffness and the mass it is attached to.
Is it true holes have a mass?
The electrons that are missing have a negative effective mass. So the holes have a positive effective mass.

Which has more mass electron or hole?
Holes have a slightly larger effective mass. I couldn't tell you what that is exactly, but the mass of an electron is:9.1094 * 10^-31 kg
Why effective mass of electron is negative at the top of valence band?
The effective mass of an electron in a solid is determined by its curvature of the energy band. At the top of the valence band, where the curvature is negative, the effective mass of the electron is also negative, reflecting the opposite relationship between the momentum and velocity of the electron in this region. This negative effective mass indicates that the electron behaves as if it has a negative charge moving in the opposite direction.
What is light and heavy hole in semiconductor?
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 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 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.
What has a lot of mass?
Black holes.
Are black holes infinite in size and mass?
No, black holes are not infinite in size and mass. They have a finite size and mass, but their density is extremely high, leading to their strong gravitational pull.
What kind of stars become black holes low mass or medium mass or high mass?
High-mass stars might become black holes, if the remaining matter (after the supernova explosion) is sufficiently large.
How do black holes survive?
it's mass
