LaAlO 3 epitaxial films with La: Al cation ratios ranging from 0.9 to 1.2 were grown on TiO 2-
terminated SrTiO 3 (001) substrates by off-axis pulsed laser deposition. Although all films …

Thermoelectric oxide thin films are promising in chip cooling. The issues on the orientation
of thin films are essential as they are related to the structures, morphologies, and …

Epitaxial VO2/TiO2 thin film heterostructures were grown on (100)(m-cut) Al2O3 substrates
via pulsed laser deposition. We have demonstrated the ability to reduce the semiconductor …

We investigate the effect of epitaxial strain on [001]-oriented LaAlO 3 using first-principles
density-functional calculations. We find a series of structural phase transitions between …

Combining temperature-dependent x-ray diffraction, Raman spectroscopy and first-
principles-based effective Hamiltonian calculations, we show that varying the thickness of …

We investigate the electronic structure of defects in LaAlO 3 (LAO) and their effects on
electronic properties of bulk and heterostructures. Our calculations indicate that vacancies …

Epitaxial strain has been extensively used to control and induce new properties in complex
oxide thin films. Understanding strain evolution and how to manipulate it are essential to the …

Pr-based cobaltites exhibit extraordinary phenomena where abrupt valence shifts trigger
coupled structural/spin-state/metal-insulator transitions. Recent work achieved strain control …
