Impact of the surface phase transition on magnon and phonon excitations in BiFeO3 nanoparticles
Ian Aupiais, Pierre Hemme, Marc Allen +8
We have performed Raman scattering measurements on BiFeO3 nanoparticles and studied both magnetic and lattice modes. We reveal strong anomalies between 140 K and 200 K in the frequ…
Size-Dependent Structural Phase Transitions in SrTiO3 Nanoparticles
Han Zhang, Sizhan Liu, Megan E. Scofield +5
Understanding the structural phase diagram of nano scale SrTiO3 has important implications on the basic physics and applications of the general class of transition metal oxide pero…
Polar State in Freestanding Strontium Titanate Nanoparticles
Trevor A. Tyson, Tian Yu, Mark Croft +6
Monodispersed strontium titanate nanoparticles were prepared and studied in detail. It is found that ~10 nm as-prepared stoichiometric nanoparticles are in a polar structural state…
A First-Principles Study of CdSe Nanoclusters Capped by Thiol Ligands
Shanshan Wu, Michael McGuigan, Amanda L. Tiano +2
A first-principles study of small CdnSen quantum dots (QDs) (n = 6, 13, and 33) has been performed for the study of QD-sensitized solar cells. We assessed the effects of the passiv…
Surface phase transitions in BiFeO3 below room temperature
R. Jarrier, X. Marti, J. Herrero-Albillos +15
We combine a wide variety of experimental techniques to analyze two heretofore mysterious phase transitions in multiferroic bismuth ferrite at low temperature. Raman spectroscopy,…
