“…These heterostructures have the potential to surmount the inherent limitations of individual 2DLMs and revolutionize their use across a range of applications. 7,8 Compared to covalent bond-based heterostructures that are accommodated with either atomic or ionic inter-diffusion, 9 van der Waals heterostructures (vdWHs) possess a sharp transition between their building blocks with an abrupt inclination of carrier concentration over the interface. 10 Moreover, the nanoscale effect of vdW heterostructures can influence the band alignment and carrier concentration inside the heterostructure leading to effective electron-hole separation at the heterojunction, a feature that could be vital for their potential applications as chemical or biological sensors.…”
