Atmospheric pressure chemical vapour deposition of boron

Boron-doped titanium dioxide (B-TiO 2) films were deposited by atmospheric pressure chemical vapour deposition of titanium(IV) chloride, ethyl acetate and tri-isopropyl borate on steel and fluorine-doped-tin oxide substrates at 500, 550 and 600 °C, respectively. The films were characterised using powder X-ray diffraction (PXRD), which showed anatase phase TiO 2 at lower deposition

Mauricio Terrones | Penn State Department of Materials

Our group constitutes a truly multidisciplinary effort focused on understanding the Physics and Chemistry of materials at the nanoscale. In particular, we study low dimensional materials that mainly involve 1- and 2-Dimensions, ranging from carbon nanotubes and graphene nanoribbons to graphene, boron nitride and chalcogenide monolayers (e.g. WS2, MoS2, NbS2 , etc).

A novel process to produce amorphous nano-sized B useful

crystallographic level, at the boron site, as well as dispersed into MgB2. In fact, the elemental B as well as most of the dopants are not suitable to be manipulated: i.e. boron, carbon and SiC are characterized by high hardness and melting point. There are two main techniques to obtain pure boron powder: via-gas [8], [9] and magnesiothermic

Doping (semiconductor) - Wikipedia

A very heavily doped semiconductor behaves more like a good conductor (metal) and thus exhibits more linear positive thermal coefficient. Such effect is used for instance in sensistors. Lower dosage of doping is used in other types (NTC or PTC) thermistors. Silicon dopants. Acceptors, p-type Boron is …

Synthesis of ultrafine Si3N4 powder in RF-RF plasma

Under this program, a process to synthesize nano-sized doped boron powder by a plasma synthesis process was developed and scaled up from 20 gram batches at program start to over 200 grams by program end. Over 75 batches of boron nanopowder were made by RF plasma synthesis. Particle sizes were typically in the 20-200 nm range.

Carbon Doping of MgB by Toluene and Malic-Acid-in-Toluene

substitute on the boron site in the MgB 2 structure. One method of obtaining carbon doped samples is to add a precursor to the magnesium/boron powder mixture that is reduced by magnesium at higher temperatures. Perhaps the most common MgB 2 additive is nanometer size SiC powder which is reduced by magnesium to form Mg
