Intrinsic Mobility Limiting Mechanisms in Lanthanum-Doped Strontium Titanate
The temperature dependent Hall mobility data from La-doped SrTiO3 thin films are analyzed and modeled considering various electron scattering mechanisms. We find that a ∼6 meV transverse optical phonon deformation potential scattering mechanism is necessary to explain the dependence of transport on temperature between 10–200 K. Also, we find that the low temperature electron mobility in intrins...
متن کاملEffect of Grinding Time on Structural and Thermal Properties of Strontium-Doped Nanostructural Lanthanum
In this work, the strontium-doped lanthanum manganite- a ceramic material- used as cathode in solid oxide fuel cells. An impression of grinding time on the structural and thermal properties of Sr-doped LaMnO3 system with La1-xSrxMnO3 (x=0.2) stoichiometric ratio was investigated. The nano crystallite LSM powder with cubic structure was prepared by varying the milling time of planetary monomill ...
متن کاملElectrical pump-and-probe study of spin singlet-triplet relaxation in a quantum dot.
Spin relaxation from a triplet excited state to a singlet ground state in a semiconductor quantum dot is studied by employing an electrical pump-and-probe method. Spin relaxation occurs via co-tunneling when the tunneling rate is relatively large, confirmed by a characteristic square dependence of the relaxation rate on the tunneling rate. When co-tunneling is suppressed by reducing the tunneli...
متن کاملMagnetic transitions and electrical transport in lanthanum strontium manganite: Effects of substitutions and high pressure
The observation of a substitution-induced ferromagnetic order ~Tc5200 K! is reported in antiferromagnetic La0.9Sr0.1MnO3 ~TN5130 K! when 0.05 of La is replaced by yttrium. Important results of ferromagnetic resonance ~FMR! and high-pressure transport studies are as follows. ~i! Data on FMR linewidth and resistivity provide evidence for the presence of microscopic magnetic inhomogeneities, possi...
متن کاملSpin Hall drag in electronic bilayers.
We predict a new effect in electronic bilayers: spin Hall drag. The effect consists of the generation of spin accumulation across one layer by an electric current along the other layer. It arises from the combined action of spin-orbit and Coulomb interactions. Our theoretical analysis, based on the Boltzmann equation formalism, identifies two main contributions to the spin Hall drag resistivity...
