Hi @raolixiang-up,
the original model did not include nitrides. See the paper in which the smact.oxidation_states
module was developed: D. W. Davies, K. T. Butler, O. Isayev, A. Walsh, Faraday Discussions 2018, 211, 553.
It should be possible to extend the dataset to include a wider range of anions (including nitrogen) following a similar procedure outlined in the paper.
I would like some additional clarity on your second point, but can I assume you are referring to the smact_filter
function for generating charge neutral compositions?
If so, the current implementation of it allows setting a threshold for the stoichiometric, but it should be simple enough for us to implement another argument to specify a fixed stoichiometric ratio.
Hope this helps!
Nice! Thanks for your reply. My second question is the same as your issue #79. I hope SMACT is getting better and better.
For your second issue were you referring to issue #76 perhaps?
I've started the process of updating the smact_filter
function to have a fixed stoichiometric ratio as an argument for generating charge neutral compositions in PR #122.
I can merge this PR later on and upload it on PyPI to make it accessible.
Nice work! In addition, it would be excellent if the anion dataset could be expanded in the smact.oxidation_states module.
Hi @raolixiang-up , I've updated the smact_filter
function in the latest version of SMACT v2.5.1 which you can pip install. I've added examples to the smact_filter
docstring to show how to use the new functionality: https://smact.readthedocs.io/en/latest/smact.screening.html
For updating the anion dataset, this is something we can look into implementing. If it is something that you require more urgently, then I am happy to discuss and collab with you into extending the dataset.
When I used Oxidation_state_probability_finder(), I found that there was no oxidation state of nitrogen atoms. In addition, can the stoichiometric ratio be fixed for charge neutrality screening?We look forward to your reply. Best wishes!
