As a semiconducting analog of two-dimensional (2D) graphene, MoS2 monolayer is a three-atom-thick layered transition-metal dichalcogenide, composed of a stratum of molybdenum atoms sandwiched between two layers of sulfur atoms. MoS2’s physical, chemical and opto- electrical properties can be tuned over a wide range by changing its interface and chemistry, opening potential for next generation two-dimensional flexible electronics. Here, we have developed several electronic circuits on paper using MoS2 and graphite (from pencil) and have studied electrical, capacitive and optoelectrical properties of the flexible composite. Via this process, we envision the evolution of on-demand device fabrication by writing prescribed or innovative ‘scripts’ on paper by combining art and science. Further, such 2D circuitry will evolve into writable, accessible, cost-effective (and disposable) electronics.
