What is the cause of electrical conductivity?

Electrical conductivity in metals is a result of the movement of electrically charged particles. The atoms of metal elements are characterized by the presence of valence electrons, which are electrons in the outer shell of an atom that are free to move about. It is these "free electrons" that allow metals to conduct an electric current.

Because valence electrons are free to move, they can travel through the lattice that forms the physical structure of a metal. Under an electric field, free electrons move through the metal much like billiard balls knocking against each other, passing an electric charge as they move.

How to Calculate Holes Diffusion Constant?

Holes Diffusion Constant calculator uses Holes Diffusion Constant = Mobility of Holes*(([BoltZ]*Temperature)/[Charge-e]) to calculate the Holes Diffusion Constant, Holes Diffusion Constant formula is based on Einstein's Equation which essentially states that the diffusion constant of holes is directly proportional to the product of the mobility of holes and the thermal voltage (kT/q). In simpler terms, it links how quickly particles diffuse through a medium with their ability to move in response to an electric field and the thermal energy present in the system. Holes Diffusion Constant is denoted by D_p symbol.

How to calculate Holes Diffusion Constant using this online calculator? To use this online calculator for Holes Diffusion Constant, enter Mobility of Holes (μ_p) & Temperature (T) and hit the calculate button. Here is how the Holes Diffusion Constant calculation can be explained with given input values -> 3.7E+8 = 150*(([BoltZ]*290)/[Charge-e]).

FAQ

What is Holes Diffusion Constant?

Holes Diffusion Constant formula is based on Einstein's Equation which essentially states that the diffusion constant of holes is directly proportional to the product of the mobility of holes and the thermal voltage (kT/q). In simpler terms, it links how quickly particles diffuse through a medium with their ability to move in response to an electric field and the thermal energy present in the system and is represented as D_p = μ_p*(([BoltZ]*T)/[Charge-e]) or Holes Diffusion Constant = Mobility of Holes*(([BoltZ]*Temperature)/[Charge-e]). Mobility of holes is the ability of an hole to move through a metal or semiconductor, in the presence of applied electric field & Temperature is the degree or intensity of heat present in a substance or object.
