hi.im studing a topic concerning the growth of anodic porous aluminium oxide on aluminium surface by process called electrolysis.during this I am confused about galvanostatic and potentiostatic electrolysis. please help me in understanding the concept behind galvanostatic reigm. ?

hmm,u mean that in bloch oscillation we are actually apllying bloch theorem also.(by letting n vary,we obtain same energy for different energies of k(wave vector)and there is no role of extended zone scheme here.am i right?

i have a question concerning BLOCH OSCILLTION.i studied that in the extended zone scheme, the energy of an electron with k=pi/d is same as with k=3 pi/d. i can't understand this because by dispersion relation as wave vector increases ,energy also increases(in extended zone scheme too) please...

hi I am student of graduate and want to clear the picture of MAGNETIC MOMENT of electron in my mind.can someone tell me that if an electron is moving in its orbit constituting its intrinsic spin(1/2) ho can it forms dipole moment(to poles) when place in magnetic field?and what is the difference...

hi i m studing AAS(atomic absorption specvtroscopy) technique.using beer"s law i plot a graph bw absorbance and concentration.then how can i make the quantitative analysis of my sample?

yes.it was typing mistake

diffration pattern gives graph bw intensity vs 2*theta.use bragg law to convert theta into your desire spacing

hi granpa, what about my question?if elements valence shell contains 2electrons then?

hartree approx. when considers the pauli exclusion principle then it becomes hatree jock approximation .hatree jock approx. also provides antisymmetric function

I have a new q,perhaps it may solve the problem, suppose the electronic sturcture of a solid that represents a two dimensional square lattice of divalent atoms can be discribed using nearly free electronmodel withaweak potentialsuchthat U<<h^2/4M(Pi^2)*(Pi/a)^2 *=multiply ^2=square where...

got it,thnx. its kf(square)=2 * pi *N /A where N/A=no. of electrons per unit area, kindly explain DISPERSION relation,

relation of fermi energy in 3D is E=h(cut square)k(square)/2m, if i want a relation of fermi energy in 2D,what should i do?
