Thermal Analysis Techniques

ABSTRACTThermal analysis techniques are routinely applied to characterize the thermal behavior of metal organic precursors used for oxide film preparation. Since the mass of films is very low, researchers do their thermal analyses on powders and consider that the results are representative of films. We will show here that, in general, this assumption is not true. Several examples involving precursors of YBa2Cu3O7-x (Ba and Y trifluoroacetates and Ba propionate) will serve to appreciate that films can behave very differently than powders due to their enhanced heat and mass transport paths. Ultimately, we will demonstrate that, in some cases, relying on powders thermal analysis may lead to erroneous conclusions.

Chalcogenide Thin Film

In this study, we present a process to deposit cadmium sulfide (CdS) thin film on glass substrate using in-house made CdS sputter target deposited by RF (radio frequency) magnetron sputtering. The bandgap of CdS film was about 2.4 eV estimated using tauc plot. Structural analysis was done using XRD and highest peak is at (101) and two other small peaks at (100) and (110) confirm CdS phase. Raman analysis was done for further confirmation of phases present in CdS film where peaks at 299.97 cm−1 and 599.8 cm−1 showed phase pure CdS film. The sputtering method used for CdS thin film preparation is an industrially viable technique and can be used for in line mass production.
