Vapor phase syntheses, including parylene chemical vapor deposition (CVD) and initiated CVD, enable the deposition of conformal polymer thin films to benefit a diverse array of applications. This short review for nanotechnologists, including those new to vapor deposition methods, covers the basic theory in designing a conformal polymer film vapor deposition, sample preparation and imaging techn...

single-walled carbon nanotubes (swnts) with high yield and quality were synthesized using chemical vapor deposition (cvd) over co-mo/ mgo nanocatalyst in a fluidized bed reactor. different parameters such as temperature, the ratio of hydrocarbon source to hydrogen, the flow rate of gas, growth time, the size of catalyst particles, heating rate, and the kind of hydrocarbon source were examined t...

can be varied from perfectly isotropic to exactly straight. Also positive or negative tapering is po~s ib le .~ Various ways of fabricating channels in silicon are The basic approach for disyussed. Some new channels are presented: the constructing channels in GPSIC's and the LPCVD covered channels. Also some silicon is almost always attention is paid to the problem of making connections as depi...

This study focuses on the manufacture of carbon nanotubes using the arc discharge method. Several independent variables were changed, such as the current (80 and 100 A), an atmosphere of open air or argon and the catalyst (no catalyst, Fe or a mixture of Fe/Co,Ni). Only one set of parameters yielded MWNTs, involving Fe as the catalyst and an open air atmosphere. I. INTRODUCTION There has been i...
