Abstract
This paper reports the synthesis of the novel single-source precursor, [{((MeInAsBu)-Bu-t)(3)}(2)(Me2InAs(Bu-t)H)(2)] and the subsequent first report of aerosol-assisted chemical vapour deposition of InAs thin films. Owing to the use of the single-source precursor, highly crystalline and stoichiometric films were grown at a relatively low deposition temperature of 450 degrees C. Core level XPS depth profiling studies showed some partial oxidation of the film surface, however this was self-limiting and disappeared on etch profiles. Valence band XPS analysis matched well with the simulated density of state spectrum. Hall effect measurements performed on the films showed that the films were n-type with promising resistivity (3.6 x 10(-3) Omega cm) and carrier mobility (410 cm(2) V-1 s(-1)) values despite growth on amorphous glass substrates.
