Interlayer excitons in CVD-grown WS2/MoS2 vertical heterostructures

Not Accessible

Your library or personal account may give you access


Heterostructures of transition metal dichalcogenides (TMDCs) have attracted attention because of their emergent optical and electronic properties. As a representative example, the presence of interlayer excitons has been reported for TMDC-based vertical heterostructures [1,2]. However, in previous studies, an observed photoluminescence (PL) peak relating to the interlayer excitons has relatively-large linewidth probably due to the presence of inhomogeneous broadening. To solve this issues, we have developed the CVD process of TMDCs with highly-uniform optical spectra and their heterostructures [3,4]. Here, we report on the observation of sharp PL peaks in high-quality WS2/MoS2 vertical heterostructures.
