Transport Studies on La, Ce and Pr nickelates
Faculty of Science, K.N. Govt P.G.College Gyanpur S.R.N Bhadohi India
The electrical conductivity (s) and Seebeck coefficient (S) of rare-earth nickelates of the type RNiO3 with R = La, Ce and Pr are reported in the temperature range 400-1200K. These nickelates are perosskite type compounds with orthorhombic unit cell. It has been concluded that they are essentially electronic conductors and both the s and S variations with temperature (T) show three regions with break temperatures T1 and T2. The majority charge carriers are holes throughout the study. The conduction mechanism has been explained on the basis of energy band diagram. Energy band gap and mobility of charge carriers have also been evaluated.
