How does a EM wave affect the charge carrier concentration in a solid semiconductor?

I am concerned about the energies of EM radiations. Like the visible has an energy in the range of 1eV, UV has an energy of 10 eV. So when we shine the EM on a semiconductor, how does it affect...

What is the difference between basis vectors and lattice vectors?

My idea about the basis vector is that it is defined within a basis of the crystal to represent how the atoms are oriented inside the basis molecule. And the lattice vectors are defined on the...
