We introduce germanium sulfide (GeS) as a new layered material for fabrication of two-dimensional van der Walls materials and heterostructures. Heterostructures of WS2/GeS were fabricated by mechanical exfoliation and dry...
A new two-dimensional C6N6/C2N van der Waals heterostructure is proposed to realize photocatalytic water splitting. The work function difference promotes charge transfer from the C2N to C6N6 layer.
