The evolution of ZnO nanowires has been studied under supersaturation of Zn metal species with and without a ZnO thin-film buffer layer on α-Al2O3 deposited by the pulsed laser ablation technique. The nanowires had diameters in the range of 30 nm to

At sufficiently high temperatures PLD deposited TaC films can be grown epitaxially on 4H-SiC (0001) substrates; at lower temperatures the films recrystallize and ball up forming a large number of pinholes. The growth temperature for epitaxy was found

We directly investigated the chemical compositional origin of surface roughness variations in air-annealed ZnO single crystal samples for annealing temperatures up to 1000 °C. Atomic Force Microscopy (AFM) showed temperature-dependent changes in sur

Cadmium sulfide (CdS) has been synthesized by a sol–gel route in order to obtain chemically protected, stable nanoparticles. The CdS nanoparticles in the SiO 2 gel matrix were dried to form monoliths of 1 in. diameter. The TEOS:H 2 O:HCl:C 2 H 5 OH

Using TEM we show that defective regions are formed in SiC by ion implantation, and that some of the regions grow at the expense of others. Using HRTEM we show that these regions contain a large number of stacking faults. It is proposed that these st

4H-SiC samples implanted with 1020 Al were annealed at various temperatures with a BN/AlN or graphite cap, and there morphological, structural, and electrical properties are compared. No blow holes were observed in either cap. Some Si out-diffuses th
