What is the voltage across a semiconductor bar if the current through it is 0.17 A? The electron concentration in the bar is 2.7 E18 cm^-3 and the electron mobility is 1000 cm^2/(V*s). Ignore the hole concentration. The bar length and the area are 0.1 mm and 500 um^2. (UNIT:V) 0.7870 V

The voltage across a semiconductor bar is 0.068 V.

Explanation:

Given that,

Current = 0.17 A

Electron concentration

Electron mobility

Length = 0.1 mm

Area = 500 μm²

We need to calculate the resistivity

Using formula of resistivity

Put the value into the formula

We need to calculate the resistance

Using formula of resistance

We need to calculate the voltage

Using formula of voltage

Put the value into the formula

Hence, The voltage across a semiconductor bar is 0.068 V.
