Question

Why energy of hole is higher than the energy of electron?

Answer 1

hey!!!!

here's your answer


the electron mobility is always how is always greater than the hole mobility because quit often the electron effective mass. the relaxation time are off turn off the same order of magnitude for electrons and holes and therefore they don't make too much difference

hope you understand

Answer 2

The vacuum electrons in the valence band are closer to the nucleus of the atom than the vacuum electrons in the conduction band. The nucleus of a specific atom pulls at the valence electrons more than the nuclei of distant atoms. ... Hence, the valence hole is heavier than a vacuum electron.
