I have read that Exciton B.E= bandgap electric - Bandgap Optical. In order to find Exciton binding energy I must know the value of Optic bandgap and electric bandgap. How we can find the electric bandgap?
I have seen JCPDS files mentioning Quality - C,H,I,O and * on the top left of each card. Which Quality JCPDS should be followed?
