In the recent years, rare earth metal (REM) sulfide thin film materials have great attentions due to their unique physical and chemical properties. The porous nanostructured morphology and wide potential window of electrode materials are very important aspects for supercapacitor applications. Therefore, REM sulfides are widely used for gas sensing, photocatalyst, glucose sensing, energy conversion and supercapacitor applications. Among the REM sulfide, ytterbium sulfide (Yb2S3) composite with graphene oxide (GO) is considered as a best candidate for negative electrode material in...
