Multiple structural transitions driven by spin-phonon couplings in a perovskite oxide
Claudio Cazorla, Oswaldo Dieguez, Jorge Iniguez
Spin-phonon interactions are central to many interesting phenomena, ranging from superconductivity to magnetoelectric effects. Yet, they are believed to have a negligible influence…
Modulation Doping of Silicon using Aluminium-induced Acceptor States in Silicon Dioxide
Dirk König, Daniel Hiller, Sebastian Gutsch +2
All electronic, optoelectronic or photovoltaic applications of silicon depend on controlling majority charge carriers via doping with impurity atoms. Nanoscale silicon is omniprese…
Intrinsic Ferromagnetism in the Diluted Magnetic Semiconductor Co:TiO
H. Saadaoui, X. Luo, Z. Salman +15
Here we present a study of magnetism in \CTO\ anatase films grown by pulsed laser deposition under a variety of oxygen partial pressures and deposition rates. Energy-dispersive spe…
On the mechanism of gas adsorption for pristine, defective and functionalized graphene
Y. You, J. Deng, X. Tan +5
Defect is no longer deemed an adverse aspect of graphene. Contrarily, it can pave ways of extending applicability of graphene. Here, we discuss the effects of three types of defect…
Thallium under extreme compression
C. Cazorla, S. G. MacLeod, D. Errandonea +3
We present a combined theoretical and experimental study of the high-pressure behavior of thallium. X-ray diffraction experiments have been carried out at room temperature up to 12…
Revisiting the zero-temperature phase diagram of stoichiometric SrCoO3 with first-principles methods
Pablo Rivero, Claudio Cazorla
By using first-principles methods based on density functional theory we revisited the zero-temperature phase diagram of stoichiometric SrCoO3, a ferromagnetic metallic perovskite t…
