Effective mass of holes?
The effective mass of a hole is a concept used in solid-state physics to describe the behavior of a hole in a crystal lattice. It represents the mass of an electron in the context of hole motion and is typically expressed as a positive value equal to the negative of the electron's mass. It is an important parameter for understanding the electrical and optical properties of semiconductors.
Why you consider only electron mass but not whole mass?
For the very simple reason that a hole has nothing in it. And if there is nothing there, it has no mass - so there is nothing to consider.
What is the mass of electron hole?
Simply, that's because in most semiconductor materials when an electric field is applied the holes have lower mobility than that of the electrons which means the hole effective mass is larger than the electron effective mass. And you can clearly see the effect of that in semiconductor nanocrystals (or as they called sometimes "quantum dots"), the energy levels in the conduction band are further apart than what they are in the covalent band due the fact that the effective hole mass is larger .... Good luck Physics PhD student, University of Toledoooo!
Is the mass of an electron greater then the mass of a proton?
No. A proton is many times more massive than an electron.
Is the mass of a proton greater then the mass of a electron?
No. A proton is many times more massive than an electron.
How does the mass of the nucleus compare to the mass of the electron?
The nucleus is far more massive than the electron cloud. The mass of the electron cloud is almost negligible compared to that of the nucleus.
Which has more massprotons or electron?
The mass of the proton is 1840 times more massive than an electron.
Why mass of electron changes with its speed?
The change in mass of an electron with speed is a result of special relativity. As an electron accelerates to high speeds, its kinetic energy increases, causing its mass to appear greater than its rest mass. This phenomenon is described by the mass-energy equivalence principle, as formulated by Einstein's famous equation, E=mc^2.
Who has the smallest mass electrons protons or neutrons?
Electrons have the smallest mass of the three particles, with protons and neutrons having roughly 1836 times more mass than an electron.
Which has a greater mass an electron or a proton?
In kilograms, an electron's mass is ~9 x 10^(-31). A proton's mass is ~1.7 x 10^(-27). The mass of the proton is more than 1000 times of an electron.
How the hole moves?
A hole can move due to external forces such as wind or water erosion, or from physical processes like landslides or sinkholes. The movement of a hole can also be influenced by the surrounding materials and can change over time due to weathering and environmental conditions.
An electron has a greater mass than a proton?
This statement is incorrect. A proton has a mass that is approximately 1836 times greater than that of an electron.
