Electrical transport properties of p-type Pb1−xCdxS epitaxial thin films

CdxPb1–xS Alloy Nanowires and Heterostructures with Simultaneous Emission in Mid-Infrared and Visible Wavelengths

“…The band gap of Cd x Pb 1– x S alloy nanowires appears less sensitive to increasing x than previously reported for this alloy system. Literature-reported linear slope values for thin films range from 1.8 to 3.5. ,,,, If linear behavior continues for increasing x , the low slope value established here for the Pb-rich range does not predict the known pure CdS band gap at x = 1.…”

“…Chemical bath deposition (CBD) is the most widely explored method for the production of polycrystalline Cd x Pb 1– x S films. The most flexible ranges of alloy composition achieved are in the Pb-rich region of the composition spectrum, − although some selected compositions have been produced, which are in the center and Cd-rich alloy region. − Regarding the previous CBD work, Rabinovich et al suggested that the wide range of solubilities claimed was not always sufficiently supported by the X-ray diffraction (XRD) results . They demonstrated CBD-grown films with x up to 0.18, as determined by detailed XRD and additionally verified by atomic absorption spectroscopy to measure the Cd/Pb ratio in the film.…”
