ELECTRONIC PRACTICE - Quiz

1) What is the reason for barrier voltage is more in silicon material?

Lower atomic number Resistance is very low Doping percentage is more Valance electrons are two only

2) What is the reason for widened barrier in a reverse biased diode?

Minority carriers in two materials are neutralised Electron in N material is drifted to positive terminal Holes in P material attracted to negative terminal Electrons and holes are attracted towards supply terminals
