| 2 | Physical vapor deposited 2D bismuth for CMOS technology显示文摘Two-dimensional(2D)bismuth,bismuthene,is an emerging pnictogen family member that has received increasing research attention in the past few years,which could yield exotic electrical,thermal,and optical properties due to unique band structure.This review provides a holistic view of recent research advances on 2D bismuth material synthesis and device applications in complementary metal oxide semiconductor(CMOS)technology.Firstly,the atomic and band structure of bismuthene is reviewed as the fundamental understanding of its physical properties.Then,it highlights material synthesis of 2D bismuth atomic sheets with emphasis on physical vapor deposition method with accurate layer controllability and process compatibility with CMOS technology.Moreover,it will survey latest applications of 2D bismuth in terms of electronic,optic,thermoelectric,spintronic and magnetic nanodevices.2D bismuth derivatives(Bi-X,X=Sb,Te,Se)will also be mentioned as a promising strategy to further improve device performance.At last,it concludes with a brief summary on the current challenges and future prospects in 2D bismuth and its derivatives for innovative electronics,sensors and other devices compatible with CMOS techniques. | Hanliu Zhao Xinghao Sun Zhengrui Zhu Wen Zhong Dongdong Song Weibing Lu Li Tao | 2020 | Journal of Semiconductors2020，41，8： | 0 |
| 3 | Synthesis of AgCl/Ti_(3)C_(2)@TiO_(2)Ternary Composite Photocatalysts for Photocatalytic Oxidation of 1,4-Dihydropyridine and Tetracycline Hydrochloride显示文摘AgCl/Ti_(3)C_(2)@TiO_(2)ternary composites were prepared to form a heterojunction structure between AgCl and TiO_(2)and introduce Ti3C2 as a cocatalyst.The as-prepared AgCl/Ti_(3)C_(2)@TiO_(2)composites showed higher photocatalytic activity than pure AgCl and Ti_(3)C_(2)@TiO_(2)for photooxidation of a 1,4-dihydropyridine derivative(1,4-DHP)and tetracycline hydrochloride(TCH)under visible light irradiation(λ>400 nm).The photocatalytic activity of AgCl/Ti_(3)C_(2)@TiO_(2)composites depended on Ti_(3)C_(2)@TiO_(2)content,and the catalytic activity of the optimized samples were 6.9 times higher than that of pure AgCl for 1,4-DHP photodehydrogenation and 7.3 times higher than that of Ti_(3)C_(2)@TiO_(2)for TCH photooxidation.The increased photocatalytic activity was due to the formation of a heterojunction structure between AgCl and TiO_(2)and the introduction of Ti3C2 as a cocatalyst,which lowered the internal resistance,sped up the charge transfer,and increased the separation efficiency of photogenerated carries.Photogenerated holes and superoxide radical anions were the major active species in the photocatalytic process. | Wu Hanliu Quan Yan Liu Meiling Tian Xuemei Ren Chunguang Wang Zhonghua | 2023 | China Petroleum Processing & Petrochemical Technology2023，25，2： | 0 |
