hey.. your anwer is here..
In an indirect band gap semiconductor, the maximum energy of the valence band occurs at a different value of momentum to the minimum in the conduction band energy: Thedifference between the two is most important in optical devices. ... Each photonof energy E has momentum p = E / c, where cis the velocity of light.
