Comparison Between Ultrasonic and Thermal Exfoliation for Molybdenum Disulfide Nanoparticles—A Multifunctional Study

The transition metal dichalcogenides (MX2, TMD) are a family of two-dimensional compounds, and MoS2 is perhaps the most representative material among them. MoS2, in its bulk form, is semiconductive, with an indirect band gap of around 1.2–1.3 eV. Monolayer MoS2, nevertheless, exhibits a direct band gap of 1.8–1.9 eV. F...
