Two-dimensional semiconductors like monolayer MoS₂ are crucial for next-generation sensing, computing, and energy technologies, but reproducible synthesis remains a major obstacle. This project uses a micro-CVD system with real-time optical monitoring to visualize growth processes and establish reliable monolayer formation. The resulting high-quality MoS₂ will be integrated into perovskite solar cells and devices such as photodetectors and FETs. Deliverables include reproducible growth protocols, MoS₂–PSC prototypes, device demonstrations, and a Q1 publication.
