Transcient analysis from electric circuits by nagoor kani

electronic device and circuit theory

Dope

Electrical characteristics of silicon and germanium upgraded by adding material in a process called doping. ?? There are only two types of doped semiconductor materials:?

p-n Transitions

One end of the silicon or germanium Crystal can be doped as p-type material, and the other end in an N-type material.


Diode operation conditions


Reverse voltage causes the lower increase.
Electrons in n-type material are attracted to positive pole of voltage source.
Holes in the p-type material are attracted to the negative pole of voltage source.


The actual characteristics of the diode


Pay attention to the regions without any bias, reverse bias forward bias conditions and.?
Note the scale for each of these conditions.
