Hii aspirants

let me clear your doubt.

In semiconductors the forbidden energy gap between valence band and conduction band is very small. Mostly it has a forbidden gap of about 1 electron volt (eV).

also conventional semiconductors like silicon have a energygap in the range of 1 - 1.5 electronvolt (eV), whereas wide-bandgap materials have bandgaps in the range of 2 - 4 eV. Generally, wide-bandgap semiconductors have electronic properties which fall in between those of conventional semiconductors and insulators.

I hope my answer will be helpful for you

Good luck l
