Functions Used
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)
Variables Used
Holes Diffusion Length - (Measured in Meter) - Holes Diffusion Length refers to the average distance the relevant charge moves in the semiconductor.
Holes Diffusion Constant - (Measured in Square Meter Per Second) - Holes Diffusion Constant refers to a material property that describes the rate at which holes diffuse through the material in response to a concentration gradient.
Hole Carrier Lifetime - (Measured in Second) - Hole Carrier Lifetime refers to the average time that a minority carrier hole exists in the material before recombining with an electron and thereby disappearing.

What is the significance of diffusion length?

Carrier diffusion length is a fundamental concept in semiconductor physics and refers to the average distance an excess charge carrier (electron or hole) can travel through a semiconductor material before it recombines with an opposite charge carrier or is otherwise lost. It's a measure of how far carriers can diffuse away from their point of generation.

How to Calculate Hole Diffusion Length?

Hole Diffusion Length calculator uses Holes Diffusion Length = sqrt(Holes Diffusion Constant*Hole Carrier Lifetime) to calculate the Holes Diffusion Length, Hole Diffusion Length is the average distance that a hole can travel through the material before recombining with an electron and thereby disappearing. It is a key parameter that characterizes the performance of p-type semiconductor devices such as solar cells, photodiodes, and transistors. Holes Diffusion Length is denoted by Lp symbol.
