Dear user, Many thanks for your reply. I am not able to understand, where I have choosen cutoff for all basis is 0. Kindly specificly gude me so I can make necessary changes at appropriate place to get proper output. Regards, Nidhi N H <[EMAIL PROTECTED]> wrote: Dear Nidhi .. Excuse-me, bu

Excuse-me, but have u noticed that you cut off for all basis is ZERO?! It means that all of your electrons are confined to the nucleous... Sorry but, No. It means: use siesta heuristics (energy shift and split norm) in order to determine the rc. Regards, Eduardo all of then, n this wa

Dear Nidhi .. Excuse-me, but have u noticed that you cut off for all basis is ZERO?! It means that all of your electrons are confined to the nucleous... all of then, n this way u have no bonds formation and a huge electronic repulsion I would say ... U need to especiffy your cut off radius resoana

Many thanks for your kind reply guiding me for corrections. I will try according to the suggestions given by you. I will like ask I wish to compute the band structure of LaS and LaAs (in first case La is +2 and in the later is +3) n=La c=car # Symbol, XC flavor,{ |r|s}

You mix up several things; I doubt it will help to resolve your problems but let us address them one by one. Sm valence configuration. 4f states are quite localized and probably (in reality, not in DFT the calculation) are not any near to the band gap. If you include them in valence states and in

Nidhi, If you need 4f in the valence as semicore, then your line should have something like n=4 3 2 4f, double-zeta. Of course the number of zetas can vary, as well as the number of polarization functions. What is the electronic configuration of your Sm pseudo? Marcos Vous avez écrit / You

Hi to all, Dear users, as we know the valence configuration of Sm is 4f6,6s2. In order to combine it with chalcogenides it is necessary to make the net ionic charge of Sm to 2, means we have to consider the 4f6 in the core. When we define the PAO basis set as %block PAO.Basis Sm 2
