Main Question or Discussion Point

Dear,
In Zener Diode, In highly Doped diode,the breakdown(Zener breakdown) occurs in small voltage.How?
Thanks& Regards,

The higher is the doping level then the narrower is the depletion region for any given reverse bias voltage. A narrower depletion region means that voltage is "blocked" over a shorter distance, meaning that the peak electric field is higher.
