Surface analysis of CdS1-xSex films grown by chemical bath deposition through AFM and Raman spectroscopy mapping

Aerosol-assisted chemical vapor deposition of MSe and MSSe thin films using zinc(ii) and cadmium(ii) single source precursors containing hybrid Se,X-PNC ligands

“…These values were comparable to those previously reported of CdSe films at around 202 AE 3 cm À1 (LO W-CdSe). 55 Second-and third-phonon modes (2LO and 3LO) were clearly observed at 408 and 614 cm À1 for 6F and at 413 and 619 cm À1 for 6Fb.…”

“…1,45 The hexagonal phase is commonly observed for ternary materials, although a mixture of both cubic and hexagonal phases are reported. 55 Annealed 3Fa exhibited growth along the (002) plane, while 5Fa seemed to lose preferential plane orientations.…”

“…On the other hand, the average composition can be easily estimated based on the observed LO phonon frequencies ( ω LOCdS / ω LOCdSe ) and comparison with those of bulk crystals. 55 The av. composition can also be estimated by plotting the difference between the observed CdS-like and CdSe-like LO phonon frequencies ( ω LOCdS − ω LOCdSe ).…”
