Correlation between surface rumpling and structural phase transformation in SrTiO3

Abstract

We present x-ray reflectivity, x-ray diffraction and atomic force microscopy measurements of single crystal SrTiO 3 taken as a function of temperature. We found a rumpling transformation of the SrTiO 3 surface after cooling the sample below ~105 K. The rumpling transformation is correlated with the cubic to tetragonal phase transformation that occurs at the same temperature.The rumpling transformation is reversible.

“…The typical roughness in BTO substrates is 40Å, one order of magnitude larger than in the T phase of SrTiO 3 (STO) substrates. 28 These results are in good agreement with those found in literature. 29 Remarkable evidence for strong ME coupling in LCMO/BTO comes from the so-called Matteucci-like magnetic hysteresis loops.…”

Unconventional Transport through Graphene on SrTiO3: A Plausible Effect of SrTiO3 Phase-Transitions

“…We further observe temperature-dependent mobility dropping at temperatures above ~30 K. These anomalies may be attributed to a change in the SO phonon scattering as a consequence of the structural phase transition of STO at 105 K. In addition, at low temperatures STO surface is known to become significantly rumpled with a gradual increase in roughness31 which may lead to a partial detachment of graphene from the substrate-surface thus reducing the gate-induced field-effect at low temperatures. However, further experimental evidences will be necessary to understand the morphology change-induced effects in graphene transport.…”

Elastically controlled manipulation of the magnetic order parameter and the metal-insulator transition in a manganite thin film

“…Recently, we observed a strong influence of applied bending stress on the saturation magnetization, M s , and the MIT of a manganite film. 24 Namely, compressive stress increases M s and the MIT. However the exclusive influence of applied elastic stress on T c of a manganite thin film has not been quantitatively reported.…”

“…Bending stress was applied using a four point mechanical jig, which applied stress uniformly over the lateral dimensions of a large sample. 24 We simultaneously measured the polarized neutron reflectivity 26,27 (PNR), , of the sample ( Fig. 1) and resistance, R, along the 1-cm-length of the sample [ Fig.…”
