[Ifeffit] [Ext] Meaning of ldosNN

Thu Feb 29 07:01:10 CST 2024

Dear Jaskirat,0 is the absorber being excited so it has a core hole, 1 is another Ni, without the core hole. They are slightly different, even if they are equivalent atoms in the alloy. Hope this helps. Best regards, AlexeySent from my T-Mobile 4G LTE Device

 Dear Alexey, Thank you for your comments. However, I still have a doubt. The ldos01. dat and ldos02. dat both correspond to Ni atoms, but the DOS looks different. I can not understand why it is so. Could you comment on this, or maybe suggest

 Hi Jeff, If i recall it correctly, ldosNN correspond to the unique potentials NN, with the relevant orbitals within each file. Just noticed that you replied in a different way, which might be confusing. Best regards, Alexey Sent from my T-Mobile

Dear listI have a question regarding DOS calculations using feff. (I am using feff8.2)I have calculated the DOS of V-doped Ni, with Ni as the central atom and Ni and V as neighboring atoms. The potential indexes are0 - Ni1 - Ni2 - VI have obtained ldos00.dat, ldos01.dat, and ldos02.dat files corresponding to the l-projected DOS for the NNth potential index. I am not clear about the meaning of ldosNN.Does it correspond to the DOS of the central atom modified by the presence of the potential index NN? If yes, does ldos02 contain the effect of both potentials 01 and 02 or that of just 02?If this is not the case, what does ldosNN mean?Kindly provide your comments to clarify this.Thanks in advance.Jaskirat BrarFMP Lab, South CampusIIT Mandi, H.P., India
