ABSTRACTClose-spaced isothermal vapor phase epitaxy (VPE) was used to grow quaternary Hg1−x−yCdxZnyTe epillayers on Cd1−zZnzTe substrates. Composition, resistivity, and carrier concentration depth profiles were determined in the epilayers. p-n junctions were produced from material with appropriate properties using the Hg diffusion method. The junctions showed excellent I-V characteristics and high spectral detectivities.

Differential Hall-effect measurements are used to obtain profiles of the mobility, μ, and carrier concentration, n, in a 6-μm-thick GaN layer grown on Al2O3 by hydride vapor phase epitaxy (HVPE). In the top 1-μm region (surface), μ ≈ 1000 cm2/V-s and n ≈ 3 × 1016 cm−3, whereas in the bottom 0.75-μm region (interface), μ ≈ 50 cm2/V-s and n ≈ 2 × 1019 cm−3. Throughout the layer, the carrier concentration correlates well with the O and Si concentrations, with [Si] dominant near the surface, and [O] dominant near the interface, proving the shallow-donor nature of O. The average mobility and carrier concentration in the top 5 μm, i.e., the “bulk” region, are close to the values deduced by a much simpler analysis, introduced previously.

ABSTRACTHigh resolution x-ray diffraction and x-ray topography study of GaN thin films, grown on sapphire (00.1) substrate by reduced pressure metalorganic vapor phase epitaxy under various conditions, were performed. An attempt was made to correlate the mobility in films with similar carrier concentration with the strain and dislocation density. X-ray topography revealed the defects present in the film.
