Metal-Insulator Transition in Mn Perovskite Compounds
We discuss Mott insulating and metallic phases of a model with eg orbital degeneracy to understand physics of Mn perovskite compounds. Quantum Monte Carlo and Lanczos diagonalization results are discussed in this model. To reproduce experimental results on charge gap and Jahn-Teller distortions, we show that a synergy between the strong correlation effects and the Jahn-Teller coupling is import...

Using electron spin resonance (ESR), a new electrically active point defect in thermally grown SiOZ films on Si has been detected. The defect has a large capture cross section for electrons when it is paramagnetic and holes when it is diamagnetic (ESR inactive). The g-tensor values, symmetry, and microwave power saturation characteristics are all similar to those of the well-known E’ family of ...

متن کاملHot electron transport in a strongly correlated transition-metal oxide
Oxide heterointerfaces are ideal for investigating strong correlation effects to electron transport, relevant for oxide-electronics. Using hot-electrons, we probe electron transport perpendicular to the La₀.₇Sr₀.₃MnO₃ (LSMO)- Nb-doped SrTiO₃ (Nb:STO) interface and find the characteristic hot-electron attenuation length in LSMO to be 1.48 ± 0.10 unit cells (u.c.) at -1.9 V, increasing to 2.02 ± ...
