Carbon, silicon and germanium atoms have four valence electrons

Home » Modern Physics » Semiconductor Electronics : Materials, Devices and Simple Circuits » Question

Carbon, silicon and germanium atoms have four valence electrons each. Their valence and conduction bands are separated by energy band gaps represented by (E_g)_C, (E_g)_Si and (E_g)_Ge respectively.
Which one of the following relationships is true in their case?

1. (E_g)_Si > (E_g)_Ge < (E_g)_C
2. (E_g)_C < (E_g)_Si
3. (E_g)_C = (E_g)_Si
4. (E_g)_C < (E_g)_Ge

Correct Option: A

Due to strong electronegativity of carbon.
