General description

Atomic number of base material: 15 Phosphorus
Phosphine is an organophosphorus compound that can be used as a ligand with electronic and steric properties. It can be incorporated into the semiconductor to tune the crystallinity and composition of the nanocrystals by enhancing their photoconductive properties.

Application

Phosphine is used primarily in the manufacture of III-IV semiconductor materials by OMCVD and as a dopant in crystalline and amorphous silicon.
Phosphine may be used to modify the n-type single walled carbon nanotubes(SWCNTs) for the development of flexible thermoelectric materials. It may also be used as a catalyst in the preparation of cyclobuteno(60)fullerenes which finds potential applications in n-type organic semiconductor.
Precursor to III-V semiconductor thin films. Also useful as a dopant for crystalline and amorphous silicon.

Recommended products

Stainless steel regulators Z527416 or Z527424 are recommended.
