I see from the solution now that the 'effective' temperature of an electron which moves from the r-valley to the L-valley is equal to T = 0.29eV*q/k ~ 3600 K, I had done this correctly.

Hi and thanks for reading, I don't really understand the valleys in the conduction band, in the E vs. k diagram, there is the L-valley, r-valley and X-valley. Each has a different momentum... and are at different energy levels. I understand that at any temperature above absolute zero, a...

Im trying this out in MATLAB, VV' = V'V = I, yup, confirmed in MATLAB. and to find V, [V,S] = eig(A); I really only know this eigenvalue/vector stuff on a superficial level. Thanks.

So, since S is a diagonal matrix containing the eigenvalues of A, V seems to be a matrix whos corresponding columns are the eigen vectors of A. A = V*S*V' checks out. I should have mentioned that S was a diagonal matrix which containes the eigenvalues of A. Ppmsrw3 thanks for your general...

Thanks pmsrw3, I am going to give that a try, I'll post my finings. and yes, A is symmetric too. Also, S is a diagonal matrix containing the eigenvalues of A.

How to solve for matrix V ?? A = V*S*V' I have A, V, and S (all matricies, square and invertable). A = V*S*V' where V' is transpose(V) I know A and S, how do I solve for V ?? S is symmetric incase that helps. Much appreciated. J.
