To avoid the technical difficulties encountered with high-temperature processing techniques, low-temperature sol−gel processes have been examined as routes to the Cr-doped olivine, Mg2SiO4, and the structural analogues Ca2SiO4 and Ca2GeO4. Gelation

Degenerately doped (>1019 cm−3) n-type InxGa1−xAs (x∼0.67) and InPyAs1−y (y∼0.65) possess a number of intriguing electrical and optical properties relevant to electro-optic devices and thermophotovoltaic devices in particular. Due to the lo

X-ray standing wave and X-ray diffraction measurements were used to determine the structure of nominal 1 monolayer and 1/2 monolayer InAs films buried in GaAs(0 0 1). The films were grown by atomic layer epitaxy using trimethylgallium, tertiarybutyla

Diffraction anomalous fine-structure measurements performed at both the Ga and As {ital K} edges have determined the Ga-As bond length to be 2.442{plus_minus}0.005thinsp{Angstrom} in a buried, 213-{Angstrom}-thick Ga{sub 0.785}In{sub 0.215}As layer g

Extended x-ray absorption fine structure performed at the Ge K edge has found the Ge-Ge and Ge-Si bond lengths in a series of crystalline Ge{sub x}Si{sub 1{minus}x} alloys (x{le}0.5) to be compositionally dependent. This accurate measurement was made

Extended x-ray absorption fine structure measurements performed at $\mathrm{In}\ensuremath{-}K$ edge have resolved the outstanding issue of bond-length strain in semiconductor-alloy heterostructures. We determine theIn-As bond length to be $2.581\ifm

The local structure within the unit cell of strained-GeSi layers grown on Si(001) has been examined by polarization-dependent extended x-ray-absorption fine structure. First-neighbor bond lengths are found to deviate only slightly from their unstrain

We have measured the potassium {ital K}{sub {beta}} and chlorine {ital K}{sub {beta}} resonant Raman x-ray scattering from KCl. Strong {ital K}-shell absorption peaks are directly reflected in the resonant Raman spectra. The emission spectra are qual

By combining the surface sensitivity of low-energy elastic photoelectrons with the position sensitivity of the x-ray standing-wave technique, we have determined both the Ag and Si atomic heights at the Si(111)$\sqrt{3}$\ifmmode\times\else\texttimes\f
