We studied the finite-size effect on the first-order metal-insulator phase transition and the accompanying tetragonal-to-monoclinic structural transition of ${\mathrm{VO}}_{2}$ films. The ${\mathrm{VO}}_{2}$ films were epitaxially grown by a metal-or

Ferroelectric PbTiO3 thin films have been prepared by a low‐pressure MOCVD process. Epitaxial films with a crystal structure of a bulk equilibrium tetragonal phase were readily obtained within a range of growth conditions. However, by providing exc

Sapphire (0001) basal plane is a commonly used substrate for film depositions. Due to the threefold rotational symmetry of the (0001) substrate surface, epitaxial films deposited are expected to form at most three variants with relative orientations
