A 'p-n' diode with hole and electron-doped lanthanum manganite

C. Mitra, P. Raychaudhuri, G. Kobernik +4

The hole-doped manganite La0.7Ca0.3MnO3 and the electron-doped manganite La0.7Ce0.3MnO3 undergo an insulator to metal transition at around 250 K, above which both behave as a polar…

Particle-Hole Symmetry and the Effect of Disorder on the Mott-Hubbard Insulator

P. J. H. Denteneer, R. T. Scalettar, N. Trivedi

Recent experiments have emphasized that our understanding of the interplay of electron correlations and randomness in solids is still incomplete. We address this important issue an…
