Why does zine oxide exhibit enhanced electrical conductivity on heating ? |
|
Answer» On heating , zinc oxide loses oxygen as : ` ZnO overset(delta)to Zn^(2+) + 1/2 O^(2) + 2e^(-) ` The ` Zn^(2+)` ions thus formed are eptrapped into the interstitional sites while the electrons are also etnrapped in the neighbouring intersitial sites. These entapped electrons enhance the electrical conductivity of ZnO. |
