Temperature induced transition from p-n to n-n electronic behavior in Ni0.07Zn0.93O/Mg0.21Zn0.79O heterojunction
Tanveer A. Dar, Arpana Agrawal, Ram J. Choudhary +3
The transport characteristics across the pulsed laser deposited Ni0.07Zn0.93O/Mg0.21Zn0.79O heterojunction exhibits p-n type semiconducting properties at 10 K while at 100 K, its c…
