The need for an Anti-Reflection Coating (ARC) on aluminum metallizations is well known. A new class of materials based on tungsten-silicide and tungsten-silicon-nitride has been developed Tor use as an ARC. It has been shown that the reflectivity (re

The (0001), (1010), and (2110) faces of Bi have been pulsed laser irradiated at 0.5–0.8 J/cm2 with a Q-switched ruby laser. Nomarski interference contrast microscopy, channeling, and selective chemical etching have been used to investigate the resp

The effect of geometry modifications of13C chemical shifts has been investigated in a small subset of molecules using both LO-INDO and Gaussian 70 (4–31) calculations. The Gaussian calculations, while known to give poor absolute shifts, compare wel

The design of a UHV sample transfer system is described. The transfer system allows irradiation of samples under vacuum in a laboratory physically removed from the location of the surface analysis system. Design considerations and advantages of this

The techniques of LEED-Spot Profile Analysis (LEED-SPA) and He+ ion channeling have been used to investigate the response of molybdenum and bismuth single crystals to pulsed laser irradiation. Samples of molybdenum with (100) orientations were irradi
