Here, undoped p-type Mg3SbxBi2−x thin films were synthesized using magnetron sputtering (three elemental targets in Ar atmosphere) with a growth temperature of 200 °C on three different substrates, namely, Si as well as c- and r-sapphire. The elemental composition was measured with energy-dispersive x-ray spectroscopy and the structure by x-ray diffraction. The electrical resistivity and the Seebeck coefficient were determined under He atmosphere from room temperature to the growth temperature. All samples are crystalline exhibiting the La2O3-type crystal structure (space group P-3m1). The observed thermoelectric response is consistent with a semiconductive behavior. With increasing x, the samples become more electrically resistive due to the increasing bandgap. High Bi content (x &lt; 1) is thus beneficial due to lower resistivity and a higher power factor near room temperature. Thermoelectric thin films synthesized at low temperatures may provide novel pathways to enable flexible devices on polymeric and other heat-sensitive substrates.","PeriodicalId":17490,"journal":{"name":"Journal of Vacuum Science & Technology A","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136066216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With a typical PEALD process cycle of 5 s Mn(amd)2 pulse, 10 s Ar purge pulse, 10 s NH3 plasma exposure, 10 s Ar purge pulse, 80 °C deposition temperature, and 60 W input power, the deposited film is continuous and smooth with a growth rate is 0.037 nm/cycle. Based on x-ray diffraction measurement, the film is determined to be η-Mn3N2 crystal structure.

This thin film was a well-adhered protective overcoating on ABS to prevent reaction with acetone vapors in a solvent resistance experiment. Scratch tests were not able to remove the overcoating from the polymer surface, which provided a 50% and 32% increase in acetone vapor resistance before initial deformation and complete structure collapse, respectively. A more aggressive tape test caused delamination of the protective coating. This proof-of-concept experiment demonstrates how 3D printing combined with ALD overcoating can alter the chemical characteristics of complex polymer architectures.","PeriodicalId":17490,"journal":{"name":"Journal of Vacuum Science & Technology A","volume":"57 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73118998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
