| 1 | Photoinduced large polaron transport and dynamics in organic-inorganic hybrid lead halide perovskite with terahertz probes显示文摘Organic-inorganic hybrid metal halide perovskites(MHPs)have attracted tremendous attention for optoelectronic applications.The long photocarrier lifetime and moderate carrier mobility have been proposed as results of the large polaron formation in MHPs.However,it is challenging to measure the effective mass and carrier scattering parameters of the photogenerated large polarons in the ultrafast carrier recombination dynamics.Here,we show,in a one-step spectroscopic method,that the optical-pump and terahertz-electromagnetic probe(OPTP)technique allows us to access the nature of interplay of photoexcited unbound charge carriers and optical phonons in polycrystalline CH_(3)NH_(3)PbI_(3)(MAPbI_(3))of about 10μm grain size.Firstly,we demonstrate a direct spectral evidence of the large polarons in polycrystalline MAPbI_(3).Using the Drude-Smith-Lorentz model along with the Frӧhlich-type electron-phonon(e-ph)coupling,we determine the effective mass and scattering parameters of photogenerated polaronic carriers.We discover that the resulting moderate polaronic carrier mobility is mainly influenced by the enhanced carrier scattering,rather than the polaron mass enhancement.While,the formation of large polarons in MAPbI_(3)polycrystalline grains results in a long charge carrier lifetime at room temperature.Our results provide crucial information about the photo-physics of MAPbI3 and are indispensable for optoelectronic device development with better performance. | Zuanming Jin Yan Peng Yuqing Fang Zhijiang Ye Zhiyuan Fan Zhilin Liu Xichang Bao Heng Gao Wei Ren Jing Wu Guohong Ma Qianli Chen Chao Zhang Alexey VBalakin Alexander PShkurinov Yiming Zhu Songlin Zhuang | 2022 | Light(Science & Applications)2022，11，8： | 4 |

| 4 | Hepatitis D:advances and challenges显示文摘Hepatitis D virus(HDV)infection causes the most severe form of viral hepatitis with rapid progression to cirrhosis,hepatic decompensation,and hepatocellular carcinoma.Although discovered>40 years ago,little attention has been paid to this pathogen from both scientific and public communities.However,effectively combating hepatitis D requires advanced scientific knowledge and joint efforts from multi-stakeholders.In this review,we emphasized the recent advances in HDV virology,epidemiology,clinical feature,treatment,and prevention.We not only highlighted the remaining challenges but also the opportunities that can move the field forward. | Zhijiang Miao Zhenrong Xie Li Ren Qiuwei Pan | 2022 | Chinese Medical Journal2022，，7： | 1 |
