a Schematic representation of the synthesis method of GNRs-1 using quateranthracene (QA) precursor. b Schematic representation of the stepwise fabrication of multiple GNRs-1/CuSe heterostructures. c GNRs-1 on Cu(111) substrate. The inset of (c) shows the high-resolution STM image of GNR-1. The bottom structural model presents the side view of GNRs-1 on the Cu(111) surface. (Voltage = 0.5 V, I-setpoint = 120 pA; inset image: Voltage = 0.2 V, I-setpoint = 120 pA). d GNRs-1 homojunctions. The bottom structural model presents the side view of GNRs-1 homojunctions on the Cu(111) surface. (Voltage = 0.8 V, I-setpoint = 50 pA). e GNRs-1/Striped-CuSe heterojunctions. The bottom structural model presents the side view of GNRs-1/Striped-CuSe heterojunctions. (Voltage = 0.5 V, I-setpoint = 80 pA). f GNRs-1/Nanopore-CuSe heterojunctions. The bottom structural model presents the side view of GNRs-1/Nanopore-CuSe heterojunctions. (Voltage = 0.8 V, I-setpoint = 50 pA).
