| 2 | Spatially Bandgap-Graded Mo S2(1-x)Se2x Homojunctions for Self-Powered Visible–Near-Infrared Phototransistors显示文摘Ternary transition metal dichalcogenide alloys with spatially graded bandgaps are an emerging class of two-dimensional materials with unique features,which opens up new potential for device applications.Here,visible–near-infrared and self-powered phototransistors based on spatially bandgap-graded MoS2(1−x)Se2x alloys,synthesized by a simple and controllable chemical solution deposition method,are reported.The graded bandgaps,arising from the spatial grading of Se composition and thickness within a single domain,are tuned from 1.83 to 1.73 eV,leading to the formation of a homojunction with a builtin electric field.Consequently,a strong and sensitive gate-modulated photovoltaic effect is demonstrated,enabling the homojunction phototransistors at zero bias to deliver a photoresponsivity of 311 mA W−1,a specific detectivity up to^10^11 Jones,and an on/off ratio up to^10^4.Remarkably,when illuminated by the lights ranging from 405 to 808 nm,the biased devices yield a champion photoresponsivity of 191.5 A W−1,a specific detectivity up to^1012 Jones,a photoconductive gain of 10^6–10^7,and a photoresponsive time in the order of^50 ms.These results provide a simple and competitive solution to the bandgap engineering of two-dimensional materials for device applications without the need for p–n junctions. | Hao Xu Juntong Zhu Guifu Zou Wei Liu Xiao Li Caihong Li Gyeong Hee Ryu Wenshuo Xu Xiaoyu Han Zhengxiao Guo Jamie HWarner Jiang Wu Huiyun Liu | 2020 | Nano-Micro Letters2020，12，2： | 4 |
| 3 | Observation of ambipolar photoresponse from 2D MoS_(2)/MXene heterostructure显示文摘Two-dimensional materials have been demonstrated as promising toolboxes for optoelectronics.Transition metal carbides and nitrides(MXenes),members of an emerging family of two-dimensional materials,have drawn extensive attention in optoelectronics owing to their excellent conductivity and tunable electronic properties.Herein,a photodetector based on the two-dimensional van der Waals heterostructure of Ti_(3)C_(2)T_(x)MXene and a MoS_(2)monolayer was constructed to observe the ambipolar photoresponse,which showed a positive photoresponse in the visible spectrum(500-700 nm)and a negative photoresponse at longer wavelengths(700-800 nm).The device exhibited a high negative responsivity of 1.9 A/W and a detectivity of 2.1×10^(10)Jones under 750 nm light illumination.Detailed experiments demonstrate that the negative photoresponse arises from the heterostructureinduced trap energy level,which confines the excited photoelectrons and leads to an inverse current.This work demonstrates a unique optoelectronic phenomenon in MoS_(2)/MXene heterostructures and provides valuable insights into the development of new photodetection materials. | Juntong Zhu Hao Wang Liang Ma Guifu Zou | 2021 | Nano Research2021，14，10： | 3 |
| 4 | Defect engineering of molybdenum disulfide through ion irradiation to boost hydrogen evolution reaction performance显示文摘The inert basal plane of molybdenum disulfide (MoS2) restrains its further hydrogen evolution reaction (HER) performance.This work attempts ion irradiation to activate inert basal plane of MoS2 nanosheet to improve its electrocatalytic performance.Experimental results demonstrate the sulphur vacancies generated by ion irradiation on the basal plane of MoS2 mainly boost the efficiency of HER performance.The moderate fluence of carbon ion irradiation gains the optimum HER performance with an onset potential of 77 mV and Tafel slope of 66 mV/dec. | Cheng Sun Peipei Wang Hao Wang Chuan Xu Juntong Zhu Yanxia Liang Ying Su Yining Jiang Wenqi Wu Engang Fu Guifu Zou | 2019 | Nano Research2019，12，7： | 3 |
| 5 | Interface engineering of high performance all-inorganic perovskite solar cells via low-temperature processed TiO2 nanopillar arrays显示文摘All-inorganic perovskite solar cells suffer from low performance due to unsatisfactory carrier transport and light harvesting efficiency.Semiconductor nanopillar arrays can reduce light reflection loss and suppress exciton recombination dynamics in optoelectronic devices.In all-inorganic perovskite solar cells,few studies employing TiO_(2)nanopillar arrays(TiO_(2)NaPAs)have been reported to improve the device performance.Herein,well-arranged TiO_(2)NaPAs are chosen to enhance the interfacial contact between perovskite and electron transporting layers for improving the carrier transport.Notably,TiO_(2)NaPAs can be directly fabricated on rigid/flexible substrates at roughly room temperature by unique glancing angle deposition,which is more available than high-temperature hydrothermal/solvothermal methods.By embedding TiO_(2)NaPAs into chemical processable CsPbI2Br layers,continuous and intimate films are readily formed,guaranteeing large physical contact for facilitating more effective electron injection and charge separation.The vertically grown TiO_(2)NaPAs also provide a straightforward electron transporting path to electrodes.In addition,TiO_(2)NaPAs can guide the incident light and enhance the light-harvesting ability of CsPbI2Br films.As a result,the solar cell with TiO_(2)NaPAs displays a power conversion efficiency of 11.35%higher than planar control of 10.04%,and exhibits better long-term thermal stability.This strategy provides an opportunity by constructing direct interfacial regulation towards the performance improvement of inorganic perovskite solar cells. | Bingkun Pan Jiahao Gu Xiaoli Xu Lingbo Xiao Jie Zhao Guifu Zou | 2021 | Nano Research2021，14，10： | 2 |

| 18 | Maillard reaction-derived laser lithography for printing functional inorganics显示文摘Photopolymerization-based additive printing of functional inorganics has drawn great attention in recent years and one important challenge is the photoresin loading with diverse inorganics. Here, we introduce a Maillard reaction-derived laser lithography strategy for an unprecedented direct printing of diverse inorganic compounds. The sugar-assisted laser lithography(SLL) is powerful to carry choice metal ions and versatile for the generation of patterned inorganic materials comprising metal oxides,metal sulfides, and metal nitrides, characterized by ferroelectric, magnetic, semiconductivity, superconductivity, or other properties. The material architecture is flexibly manipulated by the laser intensity, power, printing speed, precursor solution, and computer-aided design to satisfy the practical requirements. This work demonstrates a new possibility for the further development of laser lithography in the directly printing of feature-rich inorganic materials and devices. | Xiao Dai Yining Jiang Xiaohan Wang Fengnan Chen Liang Gao Xiaofeng Li Guifu Zou | 2022 | Science China Chemistry2022，65，7： | 0 |
| 19 | Two-dimensional(n=1)ferroelectric film solar cells显示文摘Molecular ferroele ctrics that have excellent ferroelectric properties,a low processing temperature,narrow bandgap,and which are lightweight,have shown great potential in the photovoltaic field.However,two-dimensional(2D)perovskite solar cells with high tunability,excellent photo-physical properties and superior long-term stability are limited by poor out-of-plane conductivity from intrinsic multi-quantum-well electronic structures.This work uses 2D molecular ferroelectric film as the absorbing layer to break the limit of multiple quantum wells.Our 2D ferroelectric solar cells achieve the highest open-circuit voltage(1.29 V)and the best efficiency(3.71%)among the 2D(n=1)Ruddlesden-Popper perovskite solar cells due to the enhanced out-of-plane charge transport induced by molecular ferroelectrics with a strong saturation polarization,high Curie temperature and multiaxial characteristics.This work aims to break the inefficient out-of-plane charge transport caused by the limit of the multi-quantum-well electronic structure and improve the efficiency of 2D ferroelectric solar cells. | Chen Wang Jiahao Gu Jun Li Jianyu Cai Lutao Li Junjie Yao Zheng Lu Xiaohan Wang Guifu Zou | 2023 | National Science Review2023，10，7： | 0 |
