{"doi":"10.1002/admt.202000281","title":"One‐Step Fabrication of Nanocrystalline Nanonetwork SnO<sub>2</sub> Gas Sensors by Integrated Multilaser Processing","abstract":"Abstract An integrated multilaser process is developed to fabricate nanocrystalline nanonetwork SnO 2 gas sensors in one integrated procedure, which combines electrodes fabrication, nanomaterials deposition, and postannealing. Interdigit electrodes are fabricated on an Au‐coated fused silica substrate using a picosecond (ps) laser, which ablates the Au coating from the back of the substrate to pattern the electrodes. A novel transmitted Ps laser deposition (TPLD) process is designed to deposit SnO 2 nanonetwork on the interdigit electrodes with precise deposition area control under a close target‐to‐substrate distance. The obtained SnO 2 nanonetwork is in situ postannealed by a CO 2 laser to improve the crystallinity, while the nano morphology and grain size keep intact. To investigate the morphology and formation process of the nanonetwork, the microstructure of the laser‐deposited SnO 2 layer is characterized. The crystallization control of CO 2 laser annealing is investigated through analyzing the Raman spectrum, X‐ray diffraction (XRD) patterns, and lattice structures of the samples. By exposed to H 2 atmosphere, the fabricated gas sensor is demonstrated for H 2 monitoring.","journal":"Advanced Materials Technologies","year":2020,"id":86213,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":14,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9477,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2020-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":439853,"name":"Qi Zhang","orcid":"0000-0002-6865-5981","position":1,"is_corresponding":false},{"id":439854,"name":"Zeyu Zhao","orcid":"0000-0001-8649-925X","position":2,"is_corresponding":false},{"id":439855,"name":"Yizheng Chen","orcid":"0000-0002-9162-557X","position":3,"is_corresponding":false},{"id":254095,"name":"Jennifer Gao","orcid":"0000-0003-1153-545X","position":4,"is_corresponding":false},{"id":439856,"name":"Jianhua Tong","orcid":"0000-0002-0684-1658","position":5,"is_corresponding":false},{"id":439857,"name":"Fei Peng","orcid":"0000-0002-3924-9028","position":6,"is_corresponding":false},{"id":439858,"name":"Hai Xiao","orcid":"0000-0003-1460-6241","position":7,"is_corresponding":false},{"id":439852,"name":"Jincheng Lei","orcid":"0000-0003-1272-9555","position":0,"is_corresponding":true}],"reference_count":45,"raw_metadata":null,"created_at":"2026-07-18T21:58:41.997408Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
