| Abstract Scope |
Two-dimensional transition metal dichalcogenides (TMDs), like Molybdenum disulfide (MoS2), have unique electronic and optical properties when they approach a single layer. These properties can be further tuned using strain, which we introduce via two methods: substrate and defects. The selection of substrate can introduce strain into these 2D materials, and we use SiO2, SiC, and GaAs to introduce controllable static strain. In addition, 2D MoS2 were irradiated with both heavy and light ion irradiation to fluences ranging from 1x1015 to 1x1017 cm-1, which introduced varying levels of defects. In this contribution, we utilize both experiments and modeling to understand the impact of both substrate and defect-induced strains on the behavior of MoS2. |
