{"doi":"10.1063/1.3638699","title":"Temperature dependence of the band gap of perovskite semiconductor compound CsSnI3","abstract":"<jats:p>The temperature dependence of the bandgap of perovskite semiconductor compound CsSnI3 is determined by measuring excitonic emission at low photoexcitation in a temperature range from 9 to 300 K. The bandgap increases linearly as the lattice temperature increases with a linear coefficient of 0.35 meV K−1. This behavior is distinctly different than that in most of tetrahedral semiconductors. First-principles simulation is employed to predict the bandgap change with the rigid change of lattice parameters under a quasi-harmonic approximation. It is justified that the thermal contribution dominates to the bandgap variation with temperature, while the direct contribution of electron-phonon interaction is conjectured to be negligible likely due to the unusual large electron effective mass for this material.</jats:p>","journal":"Journal of Applied Physics","year":2011,"id":38315,"datarank":11.53603015757471,"base_score":5.501258210544727,"endowment":5.501258210544727,"self_citation_contribution":0.8251887315817092,"citation_network_contribution":10.710841425993001,"self_endowment_contribution":0.8251887315817092,"citer_contribution":10.710841425993001,"corpus_percentile":null,"corpus_rank":null,"citation_count":244,"citer_count":200,"citers_with_citation_signal":200,"citers_with_endowment":200,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":42.5,"fair_percentile":4.5988586774085265,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":80196,"name":"Zhuo Chen","orcid":"0000-0001-7138-0758","position":1,"is_corresponding":false},{"id":190237,"name":"Jian J.
