Title: A small-signal generator based on a multi-layer graphene/molybdenum disulfide heterojunction

In this work, we fabricate a heterojunction small-signal generator (HSSG) based on a graphene-molybdenum disulfide (MoS{sub 2}) heterojunction. The HSSG is fundamentally different from any analog device developed previously. The HSSG is composed of two quasi-2D heterojunctions and has three terminals named injector (I), recombinator (R), and generator (G). MoS{sub 2} serves as I and G, and graphene works as R in the HSSG. The scale coefficient (β = I{sub G}/I{sub R}) of the HSSG is 1.14 × 10{sup −4} (V{sub IG, IR} = 0.2 V) to 1.95 × 10{sup −4} (V{sub IG, IR} = 1 V). The current generated from G could be as low as pA scale, which reveals the good performance of the HSSG.
