a Schematic of sample pick-up, bilayer assembly, and encapsulation for optics. b Optical micrograph of CVD-grown MoS2 monolayers and a few homobilayers, transferred to the PDMS stamp following water-assisted pick-up32 from the growth substrate. c Artificially-assembled 3R and 2H MoS2 homobilayers, fabricated by an all-dry deterministic transfer process. d First derivative of reflectivity spectra collected from three different areas of the artificially stacked 3R (red) and 2H (blue) MoS2 homobilayers, shown in (c). Spectra have been shifted for clarity.
