Domain Redistribution and Ferroelectric Phase Transition in SrTiO3 Under the Influence of an Electric Field and Mechanical Stress
Strontium titanate (SrTiO 3) is one of the best studied substances showing a displacive phase transition [1]. At ambient temperature, it exhibits a cubic perovskite structure with the space group Pm3m. On cooling, a Brillouin zone-boundary softmode drives the second-order transition to an antiferrodis-tortive phase at T C = 105 K. The primary order parameter is the antiphase rotation of TiO 6-o...
متن کاملMechanisms of charge transfer and redistribution in LaAlO3/SrTiO3 revealed by high-energy optical conductivity.
In condensed matter physics the quasi two-dimensional electron gas at the interface of two different insulators, polar LaAlO3 on nonpolar SrTiO3 (LaAlO3/SrTiO3) is a spectacular and surprising observation. This phenomenon is LaAlO3 film thickness dependent and may be explained by the polarization catastrophe model, in which a charge transfer of 0.5e(-) from the LaAlO3 film into the LaAlO3/SrTiO...
متن کاملAlternatives to Redistribution Communities in Inter-domain traffic Engineering
Today’s internet routing mainly concentrates on controlling the ingress and egress traffic which occurs through border routers. There are different ways by which we can control the traffic between autonomous systems. In most cases redistribution communities are used for the control over traffic engineering. In this paper we focus on alternative approaches like Multi Protocol Label Switching (MP...
متن کاملAnisotropic electrical resistance in mesoscopic LaAlO3/SrTiO3 devices with individual domain walls
The crystal structure of bulk SrTiO3(STO) transitions from cubic to tetragonal at around 105 K. Recent local scanning probe measurements of LaAlO3/SrTiO3 (LAO/STO) interfaces indicated the existence of spatially inhomogeneous electrical current paths and electrostatic potential associated with the structural domain formation in the tetragonal phase of STO. Here we report a study of temperature ...
