Re: [Wien] hf error -monolayer
Dear I resolved the problem for in.0 and hf calculation is OK. but I have only one question : The band number 39 is occupied. In case.inhf, I put 42 as nband. But in the band structure plot , this band (n°39) is considered as conduction band . As I know , DFT-calculation by wien2k are carried at 0 K so conduction bands are empty. Can you explain to me why ? For gap measure , It is correct to consider the band n°40 and to neglect n°39 ?

[Wien] Temperature
Dear I Explain my point of view : Using Wien2k code all calculations are done at 0 kelvin . So there is no thermal energy able to displace an electron from valence to conduction band. Conduction bands levels are therefore empty.if for example the Wien2k-estimated bandgap is of 2 eV so it is considered as semiconductor . so is it logical to speak of energy conduction level and wien2k calculates the density of charges /states in conduction band namely DOS and we know that at T=0k the material is insulator so no electron in conduction band. my second question :with respect to semiconductor definition, it is conductor at ambient temperature so KT=25 meV . do you think that this energy it sufficent to displace the electron from VB to CB with Eg =2 eV.?

[Wien] Temperature
Dear users With Wien2k I was calculated the band structure of one material which is a semiconductor . The DFT calculations in wien2k are carried at T=0 kelvin. AS I know there is no semiconductor at 0 kelvin. So How we can explain the semiconductor nature at 0 kelvin with dft calculation ?

[Wien] questions about Wien2k
Dear Im using Wien2k code and I have some questions 1) Wien2k code is based on DFT which consideres only the ground state but in the same time the code calculates the absorption spectrum. is this spectrum has a physical sense ? it is correct ? 2) the dielectric functions are calculated versus energy. What means this energy ? is it the excitation energy ? and what means the static dielectric constant Thanks for your reply ___ Wien mailing list Wien@zeus.theochem.tuwien.ac.at http://zeus.theochem.tuwien.ac.at/mailman/listinfo/wien SEARCH the MAILING-LIST at: http://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/index.html
[Wien] negative epsilon 1
Hi Im working on semiconductor material. I have calculated the real part of dielectric function (epsilon1) as function of energy. For high energy , I found epsilon1 negative ! Please can someone explain me what means this negative values ? I read that any material havig an negative epsilon1 , it becomes a metal , it is right ??

[Wien] gap
Hi Im working on electronic structure of monolayer material. I used GGA and MBJ approaches and the obtained gap is very small in comparaison with the experimental result. In the useeguide of wien2k , the authors note that MBJ increase the gap of 3D material and not the 2D one. Please can someone advices me which approach (included in wien2k code) allows to increase the gap of the monolayer ??

[Wien] sum rules-TiC
I have calculated the optical properties of TiC. I have just followed all the steps given in UG. The only difference , I haven't found the TiC.in2c in order to change TOT to FERMI but I do it in TiC.in2..I think that is ok ?? no ? My question is about its sum rules. I found : sum rule 1: Int(sigma)dw 4.6253 sum rule 2: Int(eloss.w)dw 0.1719 sum rule 3: Int(eloss/w)dw0.2839 But When I read Claudia Ambrosch-Drax's paper (Linear optical properties of solids within the full-potential linearized augmented planewave method)I found That The first two give an effective number of electrons contributing to the absorption process as a function of energy.!!! So, my calculations are wrong ?? But When I work on another compound I found That sum rule (1-2) are different . Sum rule 3 is different to = π/2 !! Can some one help me Please ?
