puneesh makhija is wrong.
Zener breakdown is due to the high electric field present
at the junction.Because of the high E , a sufficiently
strong force exerted on a bound electron by the field to
tear it out of its covalent bond . The new holeelectron pair
created increases the reverse current.(for highly doped
diodes)
Avalanche breakdown is due to collisions . A thermally
generated carrier falls down the junction barrier and
acquires energy from the applied potential . This carrier
collides with a crystal ion and imparts sufficient energy
to disrupt a covalent bond . In addition to original carrier
a new electron-hole pair is generated . This cumulative
process is referred to as avalanche multiplication .
