Phase Transitions in Nanoscale SrTiO$_{\mathrm{3}}$
ORAL
Abstract
Free standing SrTiO$_{\mathrm{3}}$ has recently been shown to be polar for \textasciitilde 10 nm particles (APL 105, 091901 (2014)). We have conducted pressure dependent x-ray diffraction on monodispersed nanoscale samples with varying particle size. Distinctly different behavior is found in the diffraction patterns for sample with reduced size. The nature of the low temperature polar state under pressure will be discussed. The results are compared with reported work on bulk SrTiO$_{\mathrm{3.\thinspace }}$This work is supported by DOE Grant DE-FG02-07ER46402.
