Various reconstructions on the GaN(0001) surface are studied by scanning tunneling microscopy (STM). Based on the comparison between the STM observations and first-principles total-energy calculations, we propose an adatom scheme for the basic $2\ifm

New normal coordinate calculations were used to relate the vibrational frequencies of silicate glasses to Si-O force constants. These appear to account for the observed frequency shifts with degree of silica polymerization. Raman spectroscopy has bee

During this third quarter effort has been directed toward the characterization of a series of thin films prepared during the first half of this contract in which the primary variable parameters are the total gas pressure (Ar + H/sub 2/ as expressed i

Sputtering preparation experiments were extended to include variations in the partial pressures of H/sub 2/ and Ar. A significant result is the demonstration of the wide control of Si-H bonding by variations in the sputtering gas pressure. Sputtered

Hydrogenated a-Si solar cells were prepared by rf-sputtering. It was found that for a-Si the surface microstructure of sputtered films can be altered by a simple post-deposition etching process and controlled by varying the film preparation condition

Aa a first step in attempting to understand the many interrelated deposition processes and film characteristics which govern sputter deposited a-Si:H film quality, a number of important basic film characteristics as a function of the preparation para
