Solid state Definition and 278 Threads

Hi. I plan on being an exchange student at Berkeley next year. I cannot find any course description for this course, I only find the description for 141A+141B: http://general-catalog.berkeley.edu/catalog/gcc_list_crse_req?p_dept_name=Physics&p_dept_cd=PHYSICS 141A. Solid State Physics. (4)...

I would like to know what is the difference between a solid state physicist and a materials engineer. I mean, do they end up doing the same kind of job or research? If they both have the same purpose, how can they do it having different backgrounds? Which preparation is better for the purpose?

My goal is to use a single signal to do two things at the same time...when DC signal is applied turn transistor1 off and turn transistor2 on. Then when signal is not applied transistor1 returns to on and transistor2 returns to off. Frequency will be no more than 60Hz. What would this circuit...

(This though came up while learning about band structure, so that is how I am going to explain it, but I think it applies equally well to a square well, for example). Say you have an electron at the Fermi level of an insulator. Then, you apply an electric field. No current flows, because all...

Hi, I would need a huge amount of assignments in solid state physics with solutions. I found assignement from other universities. Any book reference? Thank you

My tutor asked us today to consider the partition function of the following model as an aside to our topic at the moment. I went to work out the maths of it today and I'm quite stuck for how the calculation can proceed. It's a 1d closed chain with some number, n, points. Each point has some...

What are some recommended resources with good problems (and preferably solutions as well) on Solid State Physics at the level of Kittel? I'm aware of Yung-Kuo Lim's "Problems and Solutions on Solid State Physics, Relativity and Miscellaneous Topics" which has graduate qualifying exam questions...

Hi I was recently picked up solid state theory by Walter A. Harrison. I was wondering if anyone happened to have a solution set to this book as the publisher site does not have one up. Harrison has solution sets for other books up on the publisher's site so I feel like this one should be out...

Homework Statement Hi all, I have been given the task of quantifying the energy resolution of a p-i-n semi-conductor x-ray detector and present it as a value in electron volts Homework Equations %Resolution=E FWHM / Ei Where E FWHM is the full width half maximum of a peak and Ei is the...

As we know that in a metal-semiconductor junction schottky barrier arise. My question is that this is generally represented as sudden discontinuous jump in energies of conduction band on either side. But this will mean that the electric field at that point is infinite since electric field is...

Homework Statement Hi everyone, I am trying to construct qualitative band diagrams and I think I have confused myself. I am not sure on how to figure out what the electron configurations are of the orbitals when k=0. I get that at k=π/2 it is the opposite state but I can't seem to figure out...

hi can anyone help me to get complete lecture notes of a many body course which is taught according the book of "many body theory of solids" by John C.Inkson, please?

Forgive me for asking this question if the answer is obvious. The truth is I have a BENG in electrical engineering and want to know the differences between the two. From an engineer's perspective its about knowing what you can do with the devices in a useful way and design, analyze and build the...

I am interested in ultrafast optical spectroscopy of solid state materials. The unique measurements and especially the process of developing new measurement tools for the optical measurement of quantities that are hard to measure in other ways, and the learning of transferrable skills, make this...

When light passes in glass, water etc then velocity is reduced and direction changes HOW?

I am an undergrad and for the most part I am looking for a good physics class to take. I am considering taking solid state physics at the level of Kittel as its one of the only physics classes offered at the undergrad level this semester that I haven't taken. I haven't taken quantum mechanics...

Hi Everyone, I was curious as to what the most current model in solid state physics is. I've studied the Einstein and Debye Models in Stat Mech, as well as free electron and tight binding models in an intro solid state class, but these models are rather old(which does not imply they are...

So, the igbt bridge system i have going is a 600 volt 300 amp full bridge of cm300 igbt's and i was wondering if a .660uf tank capacitor is too big for my system. The mmc is made out of 2000 volt 1uf capacitors, 2 strings of 3 in series. Thank you.

hello everyone, i am looking for a comprehensive link for the topic above as i want to do some research on various applications of x-rays in solid state physics. its a personal research but i have some materials but i still feel i need a whole lot more. Any form of help would be appreciated...

Homework Statement In Kittel's 'Introduction to solid state physics' (8th ed.), on page 167, it says "The wave functions at the Brillouin zone boundary ##k=\pi/a## are ##\sqrt{2} cos (\pi x/a)## and ##\sqrt{2} sin(\pi x/a)##, normalized over unit length of line." Here I cannot understand...

I have the following homework question I am working on. I am given three scattering angles: 42.8, 73.2, 89. (in degrees) without the wavelength of the light used. I am to show that these are consistent with a diamond lattice. I started with Laue's Law: delta(k) = G and according to the...

The way I understand plasma is that is almost a gas except some of the electrons of separated from the nuclei entirely making positively charged. Is there a temperature in which Iron is by definition a gas, and not a plasma? Also, can something like a noble gas become a solid?

Homework Statement NaCl (a0 = 5.64A° ), NaBr (a0 = 5.98A° ) and KCl (a0 = 6.30A° ) all have the same structure, which is the NaCl structure. (a) Assuming the spacings are determined by the ionic radii of the relevant ions, what would value would you expect for the lattice constant of...

I've been reading Kittel's book on Solid state physics and while it's been mostly smooth sailing, the abrupt loss of rigour in places in unsettling. In particular, the bits about scattering seem to be just thrown in here and there without any rigourous mathematical treatment at all. He talks...

Hi, Could someone explain how to calculate the probability that two substitutional dopants will reside in adjacent lattice sites. For example, given a dopant concentration of 5% and a crystal structure in which each lattice site/atom is coordinated to 8 others what is the probability of...

I've never heard it said before but it appears to me that all electrical current that flows in a solid state component system; processors, diodes, transistors, resistors, etc. is eventually dissipated as heat. What are your thoughts about this?
