Spatially-resolved high-power high-temperature Raman spectroscopy as an effective tool for probing the microscopic structural variations in complex alloys: CZTSe as an example

摘要

We show that nominally similar CZTSe films may differ significantly in their microscopic structures that cannot be easily revealed by applying conventional characterization tools, including conventional Raman. CZTSs films prepared by sputtering and co-evaporation are examined in both lateral and depth direction to demonstrate the effectiveness of this spectroscopy method.
