breakdown is the process in which the reverse current increases the depletion layer width, then after a optimum level the reverse electric field or the increase in thermal energy due to increase in temprature make the electron from the valence shell of the atom to get out of it thus creating a electron hole pair whic increases current...zener breakdown occurs due to increase in electric field and avlanche brealdown accurs due to increase in thermal energy of the bonds...
