Nanocrystalline PbSe films were grown on GaAs(100) and on the As face of
GaAs(111) substrates using chemical solution deposition. The microstructure
of the films was found to be strongly affected by the deposition temperature
over a surprisingly narrow temperature range. In PbSe deposited on
GaAs(100), gradual increase in crystallite size and transition to 111
texture were obtained with increasing temperature. In contrast with PbSe
deposited on GaAs(100), the
111
texture in PbSe on GaAs(111) dominated
throughout the deposition temperature range. Since temperature directly
affects reaction rate, the temperature-dependent morphological changes
observed in this work occur primarily due to increasing sample thickness.
