mass of hole and electron
now, holes are created when the electrons are removed from there positions. so the mass of the hole produced and the electron removed should have been same. but it is said that the mass of hole is more than that of an electron.why? from where does this excess mass come from?the empty space created by the removal of electron should not exceed that of an electron. also can u explain the concept of effective mass that is why it is negative for the holes?
