An antireflective coating on Ge which combines a polycrystalline diamond film with a surface relief (moth eye) structure has been designed and successfully fabricated. This progressive gradation in the effective refractive index between air and the s

The dielectric properties of grain‐oriented thin‐film vanadium dioxide (VO2) on single‐crystal sapphire have been measured as a function of temperature across the phase transformation at 68 °C. The properties of the low‐ and high‐temperatu

The microstructure and orientation of diamond thin films grown by plasma assisted chemical vapor deposition have been studied as functions of growth temperature, substrate identity, and substrate pre‐treatment. Results indicate that for growth temp

Microlithographic patterning has been used to elucidate the mechanisms controlling diamond film nucleation and grain growth. The approach is capable of establishing a degree of control over diamond nucleation on the substrate, which can be used to im

The effects of in-situ electron and ion bombardment in quartz are compared. Both types of irradiation readily induce the metamict transformation and, furthermore, do so in linear proportion over the entire range of their combination. The results sugg

A model for the electrical degradation of MEMS switch metal microcontacts under many-cycle operation is presented. This model utilizes an asperity-based description of contacts and a general model for the degradation evolution. Calculations of switch

A method has been demonstrated to directly observe the surface crystallography and defect structures in diamond films by scanning electron microscopy. Individual diamond crystals in the polycrystalline films are polished to a rms smoothness of less t

Gamma irradiation of a simulated nuclear waste storage glass causes the formation of small bubbles in the glass by a process of network decomposition. This behavior is consistent with models previously proposed to account for electron damage in these

The radiation damage of a nuclear waste glass is shown to be associated with enhanced phase decomposition, oxygen bubble formation, and, when the glass is exposed to air saturated water, enhanced leaching.
