Shristy, as NiO is p type semiconductor this is according to fermi level analysis and in this Ni2+ and Ni3+ are interchanged during the reaction.....I'm attaching equation for your help...
In Ni0 the analysis show that the position of fermi level is nearer to valence band which indiactes that Ni0 is p type semiconductor......reverse in Zn0 ....in this the position of fermi level is nearer to conduction band So keep in mind these that ZnO is N type semiconductor
got it shristy??
