Tris(dimethylamido)antimony(III)
Synonym: Tris(dimethylamino)
CAS Number 7289-92-1 | MDL Number MFCD00269812 | EC Number 628-376-7
Tris(dimethylamido)antimony(III) was proposed as a potential precursor for the growth of Sb2Te3 films by MOCVD, as it has sufficient volatility for this purpose. Also, this product was applied as Sb source for the growth of InGaAsSb layers nearly lattice-matched to InP by MO MBE. TDMASb appeared to be useful not only as an Sb precursor but also as an additive reducing incorporation of C into the film from group-III MO sources, according to SIMS measurements. Sb(NMe2)3, combined with trimethylindium InMe3 as In source, was applied as an antimony precursor for the growth of epitaxial layers of InSb on p−InSb substrates by MOCVD. TDMASb (combined with TeiPr2 as Te source) was applied as a precursor for the growth of TDMASb on SiN by CVD at substrate temperature 350°C, press 3 Torr, run time 30min, 50 rpm. See links below
