Question 188: Semiconductors and Logic Gates

Question

If the lattice constant of this semiconductor is decreased, then which of the following is correct?

Accepted Answer

A crystal structure is composed of a unit cell, a set of atoms arranged in a particular way; which is periodically repeated in three dimensions on a lattice. The spacing between unit cells in various directions is called its lattice parameters or constants. Increasing these lattice constants will increase or widen the band-gap $$\left( {Eg} \right)$$, which means more energy would be required by electrons to reach the conduction band from the valence band. automatically $${E_c}$$ and $${E_v}$$ decreases.

Answer

All $${E_c},{E_g},{E_v}$$ increase

Answer

$${E_c}$$ and $${E_v}$$ increase, but $${E_g}$$ decreases

Answer

$${E_c}$$ and $${E_v}$$ decrease, but $${E_g}$$ increases

Answer

All $${E_c},{E_g},{E_v}$$ decrease
