Abstract
Highly crystalline lead capped lead selenide wires are generated by using unusual growth conditions falling between CVD and CVT, using lead dialkyldithiocarbamate, grey selenium powder and Si/SiO2 (100) substrates. Various morphologies can be obtained by modifying the source temperature. Nucleation of highly faceted lead selenide wires from bulk lead selenide crystallites is explored and the possible growth mechanisms are given. A reduction in the energy of the surface exposed on the microcrystal is one factor that governs the unique growth characteristics of the one dimensional structure that evolves.
