ABSTRACT
Cycling 2D crystal growth The electronic and optical properties of two-dimensional (2D) transitional metal dichalcogenides such as MoS 2 WSe could be modulated by creating in-plane superlattices heterostructures from these materials. However, single layers materials are fragile often do not withstand the processing conditions needed during subsequent steps. Zhang et al. developed a reverse-flow reactor that avoids thermal degradation unwanted nucleation. They demonstrate several examples block-by-block epitaxial growth, where surrounds WS core composition alternates between . Science , this issue p. 788
