Design and Fabrication of One- and Two-Dimensional Semiconducting Nanomaterials and Heterostructures for Low-Power Electronics Applications

The study of nanomaterials, especially their integration into nano-scale electronics, remains at the forefront of contemporary research developments. As technology shrinks in size, a need to maintain performance and low-cost solutions arises. Many such materials exhibit semiconducting properties and enhanced electrical performance when their dimensions shrink as the surface area to volume ratio increases, allowing higher sensitivity and better transport. Many previous studies show the promising capabilities of one- and two-dimensional materials, and when combined into heterostructures, they exhibit new capabilities. Some materials that have shown such unique behaviors are Graphene (Gr), Zinc Oxide nanowires (ZnO NWs), and Molybdenum Disulfide (MoS2). In this study we compare the electrical performance of ZnO NWs/Gr and ZnO NWs/MoS2 heterostructures, especially related to their semiconducting properties and viability to be marketed as diodes or other circuit elements in the electronics industry.
