Electroplating lithium transition metal oxides
Materials synthesis often provides opportunities for innovation. We demonstrate a general low-temperature (260°C) molten salt electrodeposition approach to directly electroplate the important lithium-ion (Li-ion) battery cathode materials LiCoO2, LiMn2O4, and Al-doped LiCoO2. The crystallinities and electrochemical capacities of the electroplated oxides are comparable to those of the powders sy...
متن کاملSpectral functions in doped transition metal oxides
We present experimental photoemission and inverse photoemission spectra of SrTiO3−δ representing electron doped d 0 systems. Photoemission spectra in presence of electron doping exhibit prominent features arising from electron correlation effects, while the inverse photoemssion spectra are dominated by spectral features explainable within single-particle approaches. We show that such a spectral...
متن کاملResistive Switchings in Transition Metal Oxides
Promising candidates for the next-generation memory devices have emerged one after another for the last decade. Ferroelectric random access memories (FeRAM), magnetoresistive random access memories (MRAM), phase change memories (PCM) are indeed at the dawn of the international development races. Along with those three fascinating memories, we focus here on probably the most seminal candidate of...
متن کاملSpin–Orbital Physics in Transition Metal Oxides
We present the main features of the spin-orbital superexchange which describes the magnetic and optical properties of Mott insulators with orbital degrees of freedom. In contrast to the SU(2) symmetry of spin superexchange, the orbital part of the superexchange obeys the lower cubic symmetry of the lattice and is intrinsically frustrated. This intrinsic frustration and spin-orbital entanglement...
متن کاملPhase Transition in Mixed Transition Metal Oxides under High Pressure
Mixed crystals can be categorized as the crystal in which two or more different types of atoms are present and configured. These atoms interact each other in the influence of Coulomb force of attraction and the presence of short range repulsion force. Due to this interaction they tends to be arranged in equilibrium state and forms new material. A pure crystal can be doped by impurities with pro...
