Debye Definition and 60 Threads

Homework Statement At what temperature T does the specific heat of the free electrons become larger than the specific heat of the lattice? Express T in terms of the Debye temperature and the electron concentration. Calculate T for copper (Debye = 343 K). Homework Equations...

Hi, I need to calculate the parameters of the following equation: S = (a + ((b-a)/(1+((2*pi*x)^2*c^2)))) I have the measured data of S and need the parameters a,b and c to get a curve fit in the software for analysis. If someone can help me in this regard or suggest any software that...

Hi Guyz, Why the results in the paper I've attached aren't like the results I got in my pdf? Please look at the paper in the last line, the second term doesn't correspond to what I calculated, What i calculated is in the pdf file, is it wrong? Why in my work there is exponential terms...

I am currently re-reading an old textbook on thermal physics and they have listed the final result for calculating the Debye Heat Capacity as C =9R(T/ThetaD)^3*Integral((z^4*e^z dz)/(e^z-1)^2, 0-->ThetaD/T) But they fail to mention what the R in this equation is, Could some one please tell...

Just a question: I do know it is possible to have a debye layer in a electrolyte. But is it posible to have a Debye layer in air?. I mean, if I put a single charged particle in air, do I have a layer of ionized air surrounding it??. Thanks.

I've calculates the density of aluminium using the debye theory. I found The atom density n = 2.24E28 m^-3 at 600k (assumed to be the same as at room temperature). Therefore the density is just the molecular mass m (m(grams) = (79amu / Avogadros number), multiplied by the atom density...

in a crystal, when proving the debye frequency, why is the existence of longitudinal lattice ignored? why is there longitudinal lattice in the first place?

Can someone explain to me what this is? All we were told in my Physics of Stars module was that for a plasma, L \gg \lambda_{D}, where \lambda_{D} is the Debye length. We were also told that it's an "e-folding distance" for a potential, but that doesn't help to understand it. I'm not...

1) It is desired to use an encounter with Jupiter to send a spacecraft on a trajectory which barely escapes the solar system. The spacecraft is launched from Earth onto a trajectory whose aphelion is at Jupiter’ s orbit. Determine how close to the surface of Jupiter the spacecraft must...

Greetings ! I searched the web and couldn't find it. I wan'na know the Debye length for Xenon ions. Thanks ! :smile: Live long and prosper.
