It is interesting to note that the Janus MoS2/MoSeTe (θ = 19.11°, 40.89°), WS2/WSeTe (θ = 19.11°, 30°), MoS2/WSeTe (θ = 19.11°), WSe2/MoSeTe (θ = 16.10°), WS2/MoSeTe (θ = 40.89°) vdWHs have direct bandgap with type-II band alignment, which is an essential parameter for photocatalytic water splitting applications. Furthermore, the Janus vdWHs are more efficient optical absorption from the UV to the visible light range. Our findings not only provide a compelling platform for exploring the behavior of the Janus vdWHs but also provides theoretical guidance for the designing of novel 2D nanodevices.
