______________________________________
Understanding the bandgap structure and correct nature of the electronic transition between the valence band and the conduction is very important for those scientists and researchers who are working on optoelectronics devices. In this video, I have shown a simple approach to properly understand the bandgap nature of any material using the Tauc plot method through OriginLab software. After watching this video, you will be able to determine the material has direct or indirect bandgap energy.
