摘　　要：Inorganic crystalline semiconductors are foundational to the field of solid-state electronics.1,2 Among ample examples,elemental semiconductors such as silicon(Si)and germanium(Ge)are the cornerstone of the modern electronics industry.Moving into the new era of flexible electronics,the intrinsic rigidity of both Si and Ge has largely limited the applications of these exemplary semiconductors.Although multiple organic semiconductors are developed based on their favourable soft nature,the demands for high-performance semiconductors have inspired studies of making inorganic crystalline semiconductors flexible.Due to the brittle nature of these crystalline semiconductors,the strategies to enable their flexibility mostly address the mechanics in the geometrical forms of the material—in other words,dimension reduction.For example,zero-dimensional(0D)dots,1D fibers,and 2D films have been exploited to achieve flexible electronic systems.On the device level,both dots and films have been used in the assembly of monolithic devices,whereas fibers are mostly used in the form of a nanowire bundle or a nanowire forest to assemble a planar-type device,which does not exercise the fiber form but seeks the advantage of high surface area-to-volume ratio from the nanostructure.Micron-sized fibers are the more favorable candidates for fabricating devices in the fiber form from the processing perspective.
