EPITAXY and orientation control in chemical solution deposited PbS and PbSe monocrystalline films

Interfacial characterization of chemical solution‐deposited thin films of PbSe on GaAs(100)

“…We have postulated that this nonconventional epitaxial relationship between PbSe and GaAs is formed due to the smaller lattice mismatch in the case of PbSe(111)/GaAs(100), while for the hypothetic conventional PbSe(100)/GaAs(100) orientation relationship the lattice mismatch is larger. [17] Note that the same orientation relationship was observed across the interface regardless of the interfacial layer.…”

“…Also here, a conventional epitaxial orientation relationship was obtained for PbSe on GaAs(111), while an unusual epitaxial orientation relationship was observed for PbSe on GaAs(100). [17] Prior to investigation of an interfacial layer, one must keep in mind the native oxide on the surface of GaAs. These films are usually stable, yet they can be chemically etched.…”

Phase transformation of PbSe/CdSe nanocrystals from core-shell to Janus structure studied by photoemission spectroscopy

“…To this end, single-crystal PbSe films were epitaxially grown on GaAs substrates by chemical solution deposition as described in Ref. 25. Thick layers of zinc-blende CdSe were also grown by molecular-beam epitaxy on ZnTe and InAs substrates.…”

Recent status of chemical bath deposited metal chalcogenide and metal oxide thin films

“…The CBDePbS thin films on glass substrate have been studied for various properties [125e130]. Osherov et al [131,132] deposited PbS thin films on GaAs (100) single-crystal substrates and concluded that the reagent concentrations have a profound effect on the microstructure and morphology evolution of the films. The nanocrystalline PbS thin films deposited by Patil et al [133] were used in PEC cells.…”

“…Hankare et al [178] synthesized p-type PbSe thin films on glass substrate. Osherov et al [132] studied structural, optical and electrical properties of monocrystalline PbSe thin films deposited on GaAs substrate. The nanocubes textured PbSe thin films with preferred orientation along (200) plane were deposited by Kale et al [179].…”
