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: Hg3AsSe4I 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: Hg3AsSe4I description: Hg3AsSe4I ## Chemical composition - identifier: Hg3AsSe4I description: Hg3AsSe4I ## Structure for specimen - description: Hg3AsSe4I category_description: Hg3AsSe4I ## 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: 27badc0e-39c3-4f8a-9617-5f5f68d0faf1 filename: FORCES_FC3.xz content_type: application/x-xz size: 18188016 md5: d1afb559cecdf63393c683f3589bed80 - id: 54e74065-45ab-451d-81c8-f30601660115 filename: LTC-calc.log content_type: text/x-log size: 141965 md5: 3a35e5a251e6e87d2c38fd46a09f3a1a - id: 3f104231-e3b8-4e18-88c5-beb011771a5f filename: phono3py_mlp_eval_fc3_disp.yaml.xz content_type: application/x-xz size: 24932 md5: a0837d4cb8f5c121cb3762ea6b2fb685 - id: 63e7f5ce-37fc-4f44-96cd-b5cec8166798 filename: phonopy_mlp_eval_fc2_dataset.yaml.xz content_type: application/x-xz size: 1177780 md5: 88c939411e619f2104e1e9bea65b050b - id: be0f8efc-e04c-4c46-b5aa-6ba6980fc553 filename: phonopy_training_dataset.yaml.xz content_type: application/x-xz size: 1015400 md5: e133736b8fb9cfa13caa5657989ace94 - id: 62eb74e7-9655-49b1-b236-92fe86541b51 filename: polymlp.yaml.xz content_type: application/x-xz size: 796532 md5: c1727f93144f154c1788fe08128b6aa3 - id: 9c56ea1e-6fb5-40a8-a0ae-445e4ac0a9d2 filename: vasp-settings.tar.xz content_type: application/x-xz size: 576 md5: 4da855eef541030f165fa7a4bef7540e - id: 4dae6afd-8def-4482-b294-d9b85a7d993b filename: band_pdos.png content_type: image/png size: 74455 md5: c56bfb9dc77abf4a3f91a7354e69e99f ## Thumbnail fileset_id: 4dae6afd-8def-4482-b294-d9b85a7d993b filename: band_pdos.png
