I had another excercise of the long list of the same topic (solid state physic) where I need a bit of help. All other excercise where about interband transition, dispersion relation, refracting and absorption coefficient, x-rays and so on, and I managed to solve them or I think I will be able...

So I have computate the value of the work function (but it seems too small at first look), but I still don't know why this method will fail for the short distance. I think it could have relation with the fact that the potential on the surface has to be the same everywhere but I'm not shure it's...

And why should I not be able to use this kind of method? I actually would not think about it because it seems not a useful way to resolve the problem but it's not possible to use it because there is more than one charge? If there are multiple charges, can't we simply construct an image charge...

Hi everyone, I have to solve this homework without having any books where to find the theroical topic or examples, so if you could help me find materials that I can use to understand or you want to try help me understand how to get the solution would be very helpfull. I don't have enough time to...

Hello everyone. I'm a physics student at my last year of master and I'm doing this last year in Erasmus. Doing that during the Covid situation is not the best possibile choiche (but it also was my last choiche to have an erasmus experience) and sometimes it's hard to get the occasion to ask...
