Phase change cooling schemes involving passive heat spreading devices, such as heat pipes and vapor chambers, are widely adopted for thermal management of high heat-flux technologies. In this study, carbon nanotubes (CNTs) are fabricated on a 200 lm thick sintered copper powder wick layer using microwave plasma enhanced chemical vapor deposition technique. A physical vapor deposition process is...

For wafer sizes in state-of-the-art semiconductor manufacturing ranging up to 300 mm, the uniformity of processes across the wafer becomes a very important issue. We present a fully three-dimensional model for the feature scale simulation of continuum transport and reaction determined high-pressure chemical vapor deposition processes suitable for the investigation of such nonuniformities. The n...

Two sets of hydrogenated microcrystalline silicon thin-film samples were prepared by Plasma Enhanced Chemical Vapor Deposition (PECVD) technique at different deposition conditions of excited power and pressure. The correlation between the crystalline volume fraction for the samples determined from Raman spectra and the excited power, pressure, absorption coefficient, refractive index and optica...

The simultaneous generation of dust during the deposition of semiconducting thin films by radio frequency plasma enhanced chemical vapor deposition has so far been regarded as a troublesome by-product. However, we present results from recent microstructural investigations of carbonaceous dust particles from a methane precursor that demonstrate that the technique may be suited to generating full...

Rapid continuous thermal control of chemical reactions such as those for chemical vapor deposition (CVD) growth of nanotubes and nanowires cannot be studied using traditional reactors such as tube furnaces, which have large thermal masses. We present the design, modeling, and verification of a simple, low-cost reactor based on resistive heating of a suspended silicon platform. This system achie...

Reducing solar cell thickness is an attractive way to reduce material costs. However, model calculations in this paper show that if rear surface recombination velocity (S) is greater than about 1000 cm/s, a 100-μm-thick screen-printed cell on solar-grade material has a lower efficiency than a 300-μm-thick cell. The literature demonstrates that S < 1000 cm/s is readily achievable on monocrystall...
