The potential barrier of silicon at 30^(...

The potential barrier of silicon at `30^(@)C` is `0.7 eV`. What is its value at `130^(@)C`?

Text Solution

Verified by Experts

The height of potential barrier in p-n junction is directly proportional to temperature in kelvin,
i.e., `V_ prop T. So
V_(130)/V_(30)=(130+273)/(30+273)=403/303`
or `V_(130)=V_(30)xx403/303=(0.7xx403)/303=0.93eV`
