Dear all,
I am working on Ti02, doped with Nd3+ as well as Tm3+ . When i put the
dopant in the Ti site, the formation energy is between -1 and +1 eV. When i
put the dopant in the O site, the formation energy is very high at 634 eV.
please someone help me, what could be the cause of this high formation
energy.
Kind regards
Mulwa Winfred.
