General description
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.
Atomic number of base material: 15 Phosphorus
Application
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.
Phosphine is used primarily in the manufacture of III-IV semiconductor materials by OMCVD and as a dopant in crystalline and amorphous silicon.
Precursor to III-V semiconductor thin films. Also useful as a dopant for crystalline and amorphous silicon.
Other Notes
Stainless steel regulators Z527416 or Z527424 are recommended.
