We report on the significance of thermal expansion mismatch in the heteroepitaxial growth of CdTe on highly lattice-mismatched substrates. Such substrates including Si, Ge, or GaAs are desirable for CdTe buffer layer growth and subsequent deposition

By combining a low temperature (600 °C) chemical vapor deposition process for homoepitaxial diamond and conventional ion implantation, we have made and lifted off a synthetic diamond single crystal plate. Before growth, a type Ia C(100) crystal was

Significant improvement in material and electrical properties of SiO2 films deposited by low‐temperature remote plasma‐enhanced chemical vapor deposition take place as the rf power to the plasma discharge is increased. The deposition rate increas

In this paper, the effect of thin interfacial films of SiO[sub 2] ([approximately] 20 [Angstrom]) on the electrical characteristics of metal contacts fabricated on polycrystalline and homepitaxial diamond films is studied. The diamond films were grow

Ab initio valence orbital configuration interaction calculations are used to study the energy effect of Na, H and C atom subsurface species on CH 3 chemisorption at a hollow 3-fold site on Ni(111). The lattice is modeled as an embedded three layer cl

A hydrogen plasma‐based technique for carbon removal has been combined with a modest anneal for oxide desorption at 720 °C to produce atomically clean Si(100)2×1 surfaces. Carbon and oxygen contamination can be removed from silicon surfaces by a

Low energy electron diffraction (LEED) has been used to study the effects of atomic and molecular species of hydrogen and oxygen on the reconstructed C(100)‐(2×1) surface. Thermal desorption spectroscopy was also used to study desorption products

Recent studies [Hattangady et al., Appl. Phys. Lett. 57, 581 (1990)] have shown greatly reduced interface state densities (5×1010 cm−2 eV−1) in Ge‐based, metal‐insulator‐semiconductor structures with the use of an ultrathin, pseudomorphic
