Case : Read the information and answer the question(s). The band gap of two materials is given.  Diamond : 5.5 eV GaAs : 1.43 eV

Based on this, what can you infer ?

It is easier for an electron to conduct electricity in diamond. It is easier for an electron to conduct electricity in GaAs. The conduction in these two materials solely depends upon temperature. None of the above.

It is easier for an electron to conduct electricity in GaAs.

It is easier for an electron to conduct electricity in GaAs due to smaller band gap.
