For example, here https://www3.nd.edu/~djena/kdotp.pdf it is stated that "For direct-gap semiconductors, for states near the conduction-band minimum (k = 0), the Bloch lattice-function possesses the same symmetry properties as a |S> state . In other words, it has spherical symmetry. The states...

Why is the conduction band state s-type and the corresponding valence band state p-type?

Thank you for clarification. Another question - how can we distinguish between positively and negatively charged exitons?

How can we distinguish between neutral and charged exitons?

Why is the dielectric constant smaller in few-layer materials than in bulk materials?

Do I understand it correctly that photoluminescence at a semiconductor heterojunction occurs because of intralayer recombination? If so, why can't photoluminescence occur because of interlayer recombination? Is it because momentum cannot be conserved in such a process ( like in the indirect gap...

After asking a professor about undergraduate research on Friday, I received a positive reply that very evening. The professor also asked me to send him my CV. Hovewer, it would take me some time to make it. Would it be ok to send the CV on Monday, or is it rude to take more time than him to reply?

Why does negative resistance indicate ballistic transport?

Why does the presence of an energy gap in QHE guarantee dissipationless current flow?

Can someone recommend a good book on graphene?

As a local minimum/maximum on the valence/conduction band in semiconductors.

Could someone please explain what valley degrees of freedom are?

Thanks for insight! I know this question has probably been asked a lot, but which education - STEM or liberal arts - is better for research in physics?

Thank you for your answer! If I should't choose between the schools based on my current research interests, are there any other factors I should consider?

So it really doesn't matter much which one I choose as long as I do my best and explore all the opportunities in either of the schools?
