General Questions and Answers / Re: Barder charge analysis

« on: April 26, 2022, 16:00 »

Dear Filipir,
When I run the same SiC.py, i get the following error. I am using QATK 2019.12 SP1.

So, i couldn't try all electron density for my other structures?
How do I resolve such errors?
Or does all electron density is not equipped with my QATK version?

General Questions and Answers / Spin Polarised PDOS with orbital contribution

« on: April 12, 2022, 11:29 »

Dear experts,
Is it possible to obtain the spin polarized PDOS with respective orbital contribution?
As, the PDOS has no option for orbital contributions including spin up and spin down?
Can we project the spin contribution of the orbitals?

Dear All,
How can we obtain a charge density difference plot in ATK?
I have attached a plot for reference. The reference doi for the article is https://doi.org/10.1021/acsomega.1c06860.

General Questions and Answers / Problem in bader charge calculations.

« on: February 21, 2022, 14:11 »

Dear experts,

I am trying to run bader charge calculation using PAW method using PW calculator. The atomic configuration consists of 122 atoms.
My mini workstation configuration is attached below. Is there any way to run the program in this workstation configuration? As everytime i try to run the program, all the ram are consumed and the program stops suddenly.

Yes. You have to calculate the total energy of the host material and total energy of the molecules separately. Please check your inbox. I have asked you some query.

There is a formula for adsorption energy calculation. The one you obtained is the CP corrected total energy of the complex.
For adsorption energy do,  total energy of the complex - (total energy of the host + total energy of the gas)
