Hello! I'm having my materialphysics exam in a few days, and looking some of the older exams I saw that there are many times questions about band structure and density of states. More specifically there might be a picture of some band structure plus the density of states, like this. Then they ask you to analyze this kind of a picture and give as much information as possible (according to the free electron model, nearly-free electron model and tight-binding). So what I'm asking are some basic ways for me to analyze this. Like can I see the crystal structure from this(fcc, bcc, hcp)? And for extra, what kind of chemical properties do they have? I know that fcc has good catalytic properties, but I have no clue about the others. Can I see the electron configuration? I know some basics on this, s-band is the parabolic band in around the gamma-point and p-band is a smaller parabole around the X-band (I think). But what about d and f? Also can I see how many electrons there are in a subshell? Then I'd like to know how to draw a very basic representation of the band structure with only the knowledge of the specific electron structure. I'm sorry if this should've gone to the homework forum, but this isn't homework per se so I thought to post it here. Thanks!
