摘要
Flexible devices provide advantages such as conformability,portability,and low cost.Paper-based electronics offers a number of advantages for many applications.It is lightweight,inexpensive,and biodegradable,making it an ideal choice for disposable electronics.In this work,we propose a novel configuration of photodetectors using paper as flexible substrates and amorphous Ga_(2)O_(3)as the active materials,respectively.The photoresponse characteristics are investigated systematically.A decent responsivity yield and a specific detectivity of up to 66 mA/W and 3×10^(12)Jones were obtained at a low operating voltage of 10 V.The experiments also demonstrate that neither the twisting nor bending deformation can bring obvious performance degradation to the device.This work presents a candidate strategy for the application of conventional paper substrates to low-cost flexible solar-blind photodetectors,showing the potential of being integrated with other materials to create interactive flexible circuits.
