Cu–Pt ordering is studied with cross-sectional transmission electron microscopy in p-type, n-type, and nominally undoped InAlP and In(AlGa)P layers. These different doping conditions allow us to investigate the effect of acceptor doping with magnes

Acceptor segregation is investigated as a function of compositional difference, Δx, between adjacent layers in (AlxGa1−x)0.5In0.5P heterostructures. Magnesium, Zn, Be, and Mn acceptor species are all shown to segregate out of the high band gap Al-

Oxygen incorporation in AlyIn1−yP (y ∼ 0.5) grown by metalorganic chemical vapor deposition (MOCVD) has been studied as a function of PH3 flow, growth temperature, and alloy composition. Both O2 and diethylaluminum ethoxide (DEAlO) were employed

Large substrate surface temperature decreases are observed during molecular beam epitaxy growth onto small indium bonded substrates, due to coating of the molybdenum block. These large temperature transients, along with other difficulties associated

Strain‐relaxed, compositionally graded Ge0.3Si0.7/Si heterostructures grown by ultrahigh vacuum chemical vapor deposition at 650 °C are shown to display a consistent change from p‐type to n‐type conductivity as a function of rapid thermal anne

Electron traps, hole traps, and the dominant recombination-generation (R-G) centers have been investigated with deep level transient spectroscopy and current-voltage/temperature measurements in heteroepitaxial GexSi1-x alloys with x ranging from 0.15

Deep hole traps introduced by dislocations and other strain relaxation‐induced defects in relaxed, epitaxial Ge0.30Si0.70 layers grown on Si are quantitatively compared to hole traps introduced by plastic deformation of bulk Si. Deep level transien

Substantial improvements in the quality of relaxed, heteroepitaxial GeSi layers have occurred in the past few years due to both the development of compositionally-graded buffer layers and to an improved understanding of strain-relaxation in lattice-m
