The effects of substrate temperature and near-substrate plasma density are studied for reactively sputtered dc magnetron aluminum doped zinc oxide (ZnO:Al). Plasma density is varied using an unbalanced magnetron along with external Helmholtz coils, a

The product gas yields for a 30 mTorr C2H2 13.56 MHz glow discharge were measured using mass spectrometry. The volatile products are H2, C4H2, and C6H2. A reaction mechanism has been proposed that accounts quantitatively for the yields of C4H2 and C6

The prevalence of homozygous hereditary hemochromatosis (HHC) is estimated at 1:250 in Caucasian adults. Little is known about ethnic subpopulations that might be at increased risk for this disease. HLA data have suggested a Celtic origin for HHC. Sc

The gas kinetics of a 30 mTorr radio‐frequency methane glow discharge are studied as a function of methane depletion including conditions suitable for hard carbon thin‐film deposition. Mass spectrometry is used to measure the partial pressures of

We deposit hydrogenated amorphous silicon (a‐Si:H) on a novel ‘‘macroscopic’’ trench substrate using both remote hollow cathode (HC) silane discharges and reactive magnetron sputter (RMS) deposition sources. Both methods produce state of th

The release of molecular hydrogen from the growing surface of hydrogenated amorphous silicon films is determined using an isotope labelling technique. The results demonstrate that surface‐bonded H atoms are readily abstracted by atomic hydrogen arr

A clustering algorithm is described which is powerful, in that at each iterative step of the method global information is used to constrain the algorithm's convergence towards a solution. It is stable in the face of missing data in the input; it is e

A detailed kinetic study of silane‐germane glow discharges is presented. Stable gas decomposition and production rates have been measured using mass spectrometry and a kinetic model for the plasma chemistry is developed. It is found that germane de

We have measured the initial silane and polysilane product yields from disilane decomposition in rf and dc discharges, at 25 and 250 °C and 20 Pa (0.15 Torr) pressure as typically used for a‐Si:H film deposition. From analyses of these yields we c
