In a pure semiconductor, the number of conduction electrons is 6 × 10 19 per cubic metre. How many holes are there in a sample of size 1 cm × 1cm × 1 mm?

Question

Philoid · Accepted Answer

Given: Number of conduction electrons

Since in pure semiconductor the number of holes = number of conduction electron

∴ number of holes

∴ number of holes in

∴ answer is

In a pure semiconductor, the number of conduction electrons is 6 × 1019 per cubic metre. How many holes are there in a sample of size 1 cm × 1cm × 1 mm?

In a pure semiconductor, the number of conduction electrons is 6 × 10¹⁹ per cubic metre. How many holes are there in a sample of size 1 cm × 1cm × 1 mm?
