Supercell forces and energies were calculated using the VASP code, and these data were used to develop polynomial machine learning potentials (MLPs) with the pypolymlp code. The generated MLPs are stored in polymlp.yaml.xz. Parameters required for the non-analytical term correction (Born effective charges and dielectric constants) were calculated using the VASP code with the primitive cell. These VASP results are provided in phonopy_training_dataset.yaml.xz, and the VASP input configurations can be found in vasp-settings.tar.xz. The primitive cell, unit cell, and supercell structures used for the VASP calculations are also provided in phonopy_training_dataset.yaml.xz. The internal atomic positions of the supercell were then optimized using the pypolymlp code under symmetry constraints; the relaxed structure can be found in phonopy_mlp_eval_fc2_dataset.yaml.xz (or phono3py_mlp_eval_fc3_disp.yaml.xz). Second-order force constants (fc2) can be calculated using the phonopy and symfc codes with the displacement–force dataset evaluated by the pypolymlp code, which is stored in phonopy_mlp_eval_fc2_dataset.yaml.xz. Third-order force constants (fc3) can be calculated using the built-in finite difference approach in the phono3py code with the displacement–force dataset stored in phono3py_mlp_eval_fc3_disp.yaml.xz (displacements) and FORCES_FC3.xz (forces). As an example, lattice thermal conductivities (LTCs) were calculated using the phono3py code with fc2 and fc3, and the calculation log is provided in LTC-calc.log. The harmonic phonon band structure and density of states are plotted in band_pdos.png. The band path was generated using the SeeK-path code. description_type: abstract lang: en ## Creator - name: Atsushi Togo role: author orcid: https://orcid.org/0000-0001-8393-9766 organization: National Institute for Materials Science department: Center for Basic Research on Materials ror: https://ror.org/026v1ze26 ## Contact agent - name: Atsushi Togo email: togo.atsushi@nims.go.jp organization: National Institute for Materials Science ror: https://ror.org/026v1ze26 ## Publisher organization: NIMS ror: https://ror.org/026v1ze26 ## Managing organization organization: National Institute for Materials Science department: CBRM ror: https://ror.org/026v1ze26 ## Keyword - subject: Lattice thermal conductivity schema: not_defined - subject: Cd3AsCl3 schema: not_defined ## Rights - description: Creative Commons Attribution 4.0 International identifier: https://creativecommons.org/licenses/by/4.0/ ## Other identifier(s) ## Data origin - data_origin_type: simulation ## Embargo ## Journal ## Conference ## Related item ## Funding ## Instrument ## Instrument operator ## Instrument managing organization ## Measurement method ## Specimen - name: Cd3AsCl3 description: Cd3AsCl3 ## Chemical composition - identifier: Cd3AsCl3 description: Cd3AsCl3 ## Structure for specimen - description: Cd3AsCl3 category_description: Cd3AsCl3 ## Structural feature for specimen ## Specific property for specimen ## Process for specimen treatment ## Computational method ## Energy level/transition state ## Software - name: phono3py identifier: https://github.com/phonopy/phono3py - name: phonopy identifier: https://github.com/phonopy/phonopy - name: spglib identifier: https://github.com/spglib/spglib - name: symfc identifier: https://github.com/symfc/symfc - name: pypolymlp identifier: https://github.com/sekocha/pypolymlp - name: VASP identifier: https://www.vasp.at/ - name: Seek-path identifier: https://github.com/giovannipizzi/seekpath ## Custom property ## Fileset - id: 6a6f797e-b97f-4c89-a4fd-6c6c229615cf filename: FORCES_FC3.xz content_type: application/x-xz size: 18181240 md5: 935feeb9366ae44fead182d2bf05ebda - id: 1fa186da-bbe6-4b88-a333-4003523c1d8e filename: LTC-calc.log content_type: text/x-log size: 292586 md5: ac68ea2ff3789521177c2583a0e2d8d2 - id: e6bbc846-9ffd-49c9-adb6-ac9be81e305b filename: phono3py_mlp_eval_fc3_disp.yaml.xz content_type: application/x-xz size: 36284 md5: 3271eee02cd5b459d19ed472c5252925 - id: 1823ef6c-d26d-4b14-ad6d-117b5d84b047 filename: phonopy_mlp_eval_fc2_dataset.yaml.xz content_type: application/x-xz size: 1830168 md5: f4dd8951ce2e3a8e3335edec90ec4551 - id: df33660c-bef2-4091-8a5b-54f7aee2312b filename: phonopy_training_dataset.yaml.xz content_type: application/x-xz size: 788520 md5: b4bb3634129525bcad1ac04233c9f5f4 - id: cc886fdb-5c5a-4b71-b122-7d6bb2fcf0a6 filename: polymlp.yaml.xz content_type: application/x-xz size: 283916 md5: 656348df1d9ba65981599fa853a8a9cf - id: d974fbc8-f7bb-4522-9e59-c41d0f8e412d filename: vasp-settings.tar.xz content_type: application/x-xz size: 572 md5: 37fcf974d677e2a0b0ef566c4cfecd31 - id: c2480c0a-a003-462a-b5d0-bc318dec40f1 filename: band_pdos.png content_type: image/png size: 120936 md5: ade23dc2c0e291f4dc967251ecc9aa34 ## Thumbnail fileset_id: c2480c0a-a003-462a-b5d0-bc318dec40f1 filename: band_pdos.png
