Van der Waals Template‐Assisted Growth of Two‐dimensional Sb2S3

open access: yesAdvanced Science, EarlyView.
Van der Waals (vdW) template‐assisted growth of atomically thin two‐dimensional (2D) Sb2S3 on monolayer MoS2 single crystals is demonstrated, overcoming its thermodynamically preferred one‐dimensional (1D) growth. The resulting sub‐8 nm nanosheets show uniform coverage, atomically sharp interfaces, and enhanced broadband optoelectronic performance as ...
