Questions
The contribution in the total current flowing through a semiconductor due to electrons and holes are ¾ and ¼ , respectively. If the drift velocity of electrons is 5/2 times that of holes at this temperature, then the ratio of concentration of electrons and holes is
detailed solution
Correct option is A
As we know current density J = nqv⇒Je=neqve and Jh=nhqvh⇒JeJh=nenh×vevh⇒3/41/4=nenh×520⇒nenh=65Talk to our academic expert!
