摘　　要：Self-powered microelectronics are essential for the sustained and autonomous operations of wireless electronics and microrobots.However,they are challenged by integratable microenergy supplies.Herein,we report a single-layer(SL)MoS_(2)/graphene heterostructure for stable Zn-ion microbatteries.The MoS_(2)/graphene heterostructure not only provides high chemical affinity for Zn and generates perfect lattice matching for Zn(002)deposition,but also facilitates homogeneous current density distribution.As a result,Zn metal is reversibly epitaxially plating/stripping at/from the heterostructure,without the formation of dendrites.The MoS_(2)/graphene-based Zn||MnO2 microbattery with a tiny footprint area sub-0.1 mm2 shows a stable high capacity of 0.16 mAh cm-^(2)at 0.5 mA cm-^(2)within 470 cycles.Using a single piece of crystalline MoS_(2)/graphene film,on-chip microbatteries and transistors were simultaneously fabricated via a facile lithography process,achieving highly integrated self-powered field-effect transistors and photodetector.The SL MoS_(2)/graphene-based self-powered monolithically integrated microsystem paves a new way for the multi-functionalization and miniaturization of next-generation electronics.
