| 1 | 外延生长范德华金属-半导体NbS2/MoS2异质结用于增强晶体管和光电探测器性能显示文摘基于过渡金属硫族化合物的二维材料异质结,由于其在下一代高性能集成光电子器件中的潜在应用而备受关注.虽然目前异质结制备很广泛,但是外延生长具有干净锐利界面的原子级别厚度金属-半导体异质结仍然备受挑战.另外,基于金属-半导体异质结的光电性能还鲜有研究.这里,我们报道了高质量垂直金属-半导体异质结的合成,其中金属性质的单层NbS2外延生长于单层MoS2表层.使用NbS2作为电极接触的MoS2晶体管,其迁移率和电流开关比相对于Ti/Au接触的MoS2晶体管分别提升了6倍和2个数量级.另外,基于NbS2作为电极接触的MoS2光电探测器,其响应时间和光响应可以分别提升至少30倍和20倍.本工作通过简单的化学气相沉积(CVD)方法制备的原子级别厚度的金属-半导体异质结和二维金属材料在接触方面的作用为其在光电子器件中的应用奠定了基础. | 张鹏 边策 叶家富 程宁燕 王兴国 江华宁 魏怡 张亦玮 杜轶 鲍丽宏 胡伟达 宫勇吉 | 2020 | Science China Materials2020，63，8： | 3 |
| 2 | Self-organization of various“phase-separated”nanostructures in a single chemical vapor deposition显示文摘Chemical vapor deposition(CVD)is one of the most versatile techniques for the controlled synthesis of functional nanomaterials.When multiple precursors are induced,the CVD process often gives rise to the growth of doped or alloy compounds.In this work,we demonstrate the self-assembly of a variety of‘phase-separated’functional nanostructures from a single CVD in the presence of various precursors.In specific,with silicon substrate and powder of Mn and SnTe as precursors,we achieved self-organized nanostructures including Si/SiOx core-shell nanowire heterostructures both with and without embedded manganese silicide particles,Mn11Si19 nanowires,and SnTe nanoplates.The Si/SiOx core-shell nanowires embedded with manganese silicide particles were grown along the<111>direction of the crystalline Si via an Au-catalyzed vapor-liquid-solid process,in which the Si and Mn vapors were supplied from the heated silicon substrates and Mn powder,respectively.In contrast,direct vapor-solid deposition led to particle-free<110>-oriented Si/SiOx core-shell nanowires and<100>-oriented Mn11Si19 nanowires,a promising thermoelectric material.No Sn or Te impurities were detected in these nanostructures down to the experimental limit.Topological crystalline insulator SnTe nanoplates with dominant{100}and{111}facets were found to be free of Mn(and Si)impurities,although nanoparticles and nanowires containing Mn were found in the vicinity of the nanoplates.While multiple-channel transport was observed in the SnTe nanoplates,it may not be related to the topological surface states due to surface oxidation.Finally,we carried out thermodynamic analysis and density functional theory calculations to understand the‘phase-separation’phenomenon and further discuss general approaches to grow phase-pure samples when the precursors contain residual impurities. | Jinmei Wang Dongyue Xie Zhen Li Xiaohang Zhang Xing Sun Amanda L.Coughlin Thomas Ruch Qiang Chen Yaroslav Losovyj Seunghun Lee Heshan Yu Haidong Zhou Haiyan Wang Jian Wang Shixiong Zhang | 2020 | Nano Research2020，13，6： | 0 |
