The discussion confirms that direct and indirect band gaps are not exclusive to semiconductors; they also occur in other materials such as insulators and metals. Notable examples include diamond, which is an insulator, and various studies on magnetic insulators and transitional metal oxides. Resources such as the RP Photonics Encyclopedia and specific research articles provide insights into these phenomena beyond traditional semiconductor contexts. The conversation emphasizes the importance of exploring diverse materials to understand band gap behavior comprehensively.
PREREQUISITESResearchers, materials scientists, and physicists interested in the electronic properties of solids, particularly those studying band gaps in non-semiconductor materials.
We all know how to google and look at wiki. There is really no need to give a wiki link.Baluncore said:
Note that while the article does focus on semiconductors, the first example it gives of a band gap, in the figure at the top of the page, is in diamond, which is not a semiconductor but an insulator.qnach said:
Please calm down. The reply by @Baluncore was meant to be helpful without outright giving you the answer to your question. It is ironic that you say that you know how to look this up on wiki/Google, since that will give you the answer directly. Your original thread title was pretty terse, so I added to it to make it more descriptive about the same time that Baluncore replied. If you do a Google search on the better thread title, you will see your direct answer.qnach said:
One could have searched on "direct/indirect band gaps in metals, insulators, dielectrics, . . . . " When I searched on "direct/indirect band gaps in insulators", I found the artlcle berkeman cited, "Band Gap" in theqnach said:
