| Popis: | Monolayer semiconductors have the potential to transform the industry, but their intrinsic properties are difficult to characterize due to strong interaction with the environment. This study uses multidimensional coherent spectroscopy to measure the intrinsic homogeneous linewidth of a monolayer transition-metal dichalcogenide that has been isolated from its environment through encapsulation. The measurements reveal that the linewidths become substantially narrower after encapsulation, indicating reduced sample degradation. These findings have the potential to impact the materials and process-control methods used in the semiconductor industry. |
