Question

Calculate the barrier potential for a Schottky junction comprised of metal and AlGaAs. Given, work function of metal is 4.4 eV and work function of AlGaAs is 4.0 eV

Answer 1

Answer:

Chernozem is a black-colored soil containing a high percentage of humus and high percentages of phosphoric acids, phosphorus, and ammonia. Chernozem is very fertile and can produce high agricultural yields with its high moisture storage capacity.

Answer 2

Explanation:

Is the semiconductor N-type or P-type? Explain how you know.

Solution:

According to the Poisson equation, dE

dx = ρ ( x)

KSε 0

. We see from the figure that

dE

dx

> 0 in the semiconductor. So the depleted charge must be positive, which

means this is an N-type semiconductor
