Data are presented which demonstrate how the dihydride bonding density in hydrogenated amorphous silicon produced by reactive rf sputtering may be controlled through variation of the rf sputtering power. It is suggested that as the power is increased

Data are presented for a series of samples of varying H content which show a‐Si:H to contain both a random, dilute distribution of H and a form of clustering. The dilute phase is shown to have a local H density of approximately 3.5×1021 cm−3 reg

Proton spin-lattice relaxation time (T1) measurements (made at 300K and 35 MHz) on reactively sputtered amorphous silicon-hydrogen alloys are correlated with the Fourier Transformed Free Induction Decay (FTFID) spectra and infrared absorption measure

Hydrogenated a-Si films containing exclusively monohydride bonding have been produced over a range of hydrogen densities between 0 and 20 at. % by reactive sputtering. Deposition, conductivity, activation energy, and optical gap data are presented fo

The effect of prolonged light exposure on photovoltaic quality of glow discharge amorphous silicon films has been studied by the surface photovoltage technique. Two principal results have been observed. (i) The minority‐carrier diffusion length deg

High-resolution nuclear magnetic resonance using magic-angle spinning has been applied to reactively sputtered amorphous Si-H. The line broadening expected from dispersion in the paramagnetic shielding due to charge-density variations is calculated a

We present magnetic resonance data from a series of a‐Si(H) samples deposited under varied hydrogen partial pressures. This parameter has been shown to be directly related to the sample‐wide average proton density. The other sputtering parameters

NMR data are presented for reactively sputtered amorphous silicon-hydrogen alloys (a-Si(H)). Measured differences in two of the samples are attributed to two distinct morphologies: a mixed phase (monohydride and dihydride) and a purely monohydride co

The design and construction features of a monolithic, series-connected, amorphous silicon solar cell are presented in this report. Each large-area individual cell was to measure 0.5 cm x 10.0 cm. The technology and systems capabilities of continuous,
