BPSG, USG | Silie Glass Films | Silicon Valley …

Borophosphosilie glass (BPSG) is a coating made from a mixture of oxygen and hydrides of silicon (silane – SiH 4), boron (diborane – B 2 H 6), and phosphorus (phosphine – PH 3). It is also called a doped oxide film because it is similar to silicon dioxide with the addition boron and phosphorus, which change its thermal properties.

Superconductivity in heavily boron-doped silicon …

Recently, we discovered superconductivity in a closely related system: heavily boron-doped silicon carbide. The sample used for that study consisted of cubic and hexagonal SiC phase fractions and hence this led to the question which of them participated in the superconductivity.

A variety of synthesis routes were researched and tested in this project in an attempt to synthesise silicon-doped boron carbide nanostructures. This is a potentially interesting material as it has been theoretically predicted that the addition of Si would suppress a potentially weak polytype of boron carbide resulting in significant increase in performance particularly for armour appliions.
