By growing lateral heterostructures of monolayer MoS2 with different Mo isotopes, researchers observed intrinsic isotope effect on photoluminescence, revealing how phonons couple strongly with excitons to anomalously shift the optical band gap in 2D materials compared to conventional semiconductors.
This study presents a novel approach for tailoring the optical and electronic properties of 2D materials through isotope engineering for future optoelectronic devices.
