The discussion revolves around identifying an accurate method for determining the band gap of semiconductors, with a specific focus on spectroscopy as a potential technique.
The conversation is ongoing, with participants seeking clarification on fundamental concepts related to spectroscopy and band gaps. Some have expressed familiarity with the concepts but are looking for deeper understanding.
There is a mention of previous readings on spectroscopy, indicating that some participants may be grappling with the complexity of the topic. The thread has been moved to the homework forum, suggesting a focus on academic assistance.
1. I have already read the method in which spectroscopy is performed. But I did not understand at all. If this method is accurate, how does it work?Baluncore said:Spectroscopy?
The band gap of what?

Yes, I knew and of course, thank you for the reminder.Baluncore said:1. Do you understand how the wavelength and energy of a photon are related?

2. Do you understand that an atoms electrons may only have specified energy levels, and that there are gaps between those energy levels?
