    Exploring Semiconductors: Understanding Excitons and their Bohr Radius

    With regards to semiconductors - am I correct in thinking the term 'exciton' refers to an electron/hole pair? Also what does it mean when I am told that the Bohr radius of a silicon exciton is 5nm - how can such an entity have a set radius?

    Indirect vs. Direct Bandgap Semiconductors

    I have one question to trouble you. Why some semiconductors have a direct bandgap, while some have an indirect bandgap? Is there any very crude "thumb rule" of predicting/justifying it? Thanks a lot

    Question About Indirect vs. Direct Bandgap Semiconductors

    Let's say I have an unknown material and I wanted to determine whether it is has an indirect or a direct bandgap. Is there a standard experiment for doing this without assuming we know the bandgap energy a priori? eNtRopY
