∼ 1 micron thick Cu2−xMnxO films were grown both on Au-coated and uncoated (001) Si from sulphate solutions at 60°C, several hundred degrees lower than normally used for growth of dilute magnetic semiconductors. The Mn concentration in the films was controlled very sensitively by controlling both the ratio of Mn:Cu in…

Photoluminescence measurements have been performed at low temperature on crystalline $\mathrm{Si}∕\mathrm{Si}{\mathrm{O}}_{2}$ quantum wells as a function of thickness. Three distinct electron-hole (e-h) phases are clearly identified in these structures: the electron-hole liquid, the electron-hole plasma, and the free…

High-quality single-crystal diamond films were homoepitaxially grown by chemical vapor deposition onto low cost high-pressure high-temperature diamond substrates. The transport properties of the obtained samples were studied by photoresponse characterization. Fast ultraviolet (5 ns) laser pulses at 215 nm were used as…

A method for atomic-orbital orientation determination at each $k$ point has been developed. The three-dimensional Cu Fermi surface (FS) structure was measured and visualized by stacking a series of photoelectron intensity angular distribution (PIAD) at different photon energies. PIADs from the Cu(001) surface were obt…

We calculate the free energy for a crystalline ZrO(2) with a soft mode by the first-principles method, using the double-well energy-displacement relation. The soft-mode branch is considered as an ensemble of independent anharmonic oscillators of the parabola-plus-Gaussian or of the 2-4 polynomial forms. The anharmonic…
