| Abstract Scope |
Maintaining the structural stability of atomically thin molybdenum disulfide (MoS₂) is critical for high-temperature nanoelectronic and optoelectronic applications. This study investigates the thermal durability and electrical performance of MoS₂ flakes synthesized by chemical vapor deposition and mechanical exfoliation under prolonged heating in ambient air. Atomic force microscopy and Raman spectroscopy revealed that chemically synthesized flakes developed visible surface cracks, while mechanically exfoliated flakes largely retained their structural integrity. Both samples showed reductions in thickness and surface coverage over time, although degradation was less severe in exfoliated flakes. Electrical measurements of MoS₂-based two-terminal devices during extended heating showed a gradual increase in current under constant voltage. These findings provide insight into the degradation behavior and long-term stability of MoS₂, supporting the design of more reliable devices for elevated-temperature applications. |
