Question

Diffusion current can be correlated with different conditions by which equation

Answer 1

Answer:

The diffusion current density can be calculated by equation 1. ... n1 = (1.5 · 1010) cm−3)2 1017cm−3 = 2.25 · 103cm−3 1 Page 2 Because the doping varies linearly the derivation of p and n can be evaluated by equation 1.3 and 1.4.

Explanation:

Diffusion current = the movement caused by variation in the carrier concentration. Drift current = the movement caused by electric fields. Direction of the diffusion current depends on the slope of the carrier concentration. Direction of the drift current is always in the direction of the electric field.

Answer 2

Concept Introduction: Diffusion Current is the current induced in a semiconductor due to the diffusion of Electrons and Holes.

Explanation:

We have been Given: What is Diffusion Current.

We have to Find: The equation of Diffusion Current.

Final Answer: The Equation of Diffusion Current is:

$n1 = (1.5 \times {10}^{10} {cm}^{ - 3} )^{2}$
