Hello everyone. please help me
I want to know why titanium nitride(TiN) has better electrical conductivity than titanium oxide(TiO2).
Thesedays, i did some experiments about PEMFC bipolar plate.
I installed TiN coating to titanium substrate. And, interfacial contact resistance was improved.
But. I dont know why transition metal nitride (CrN, TiN etc) has good electrical conductivity.
