From: Controlling interlayer excitons in MoS2 layers grown by chemical vapor deposition
a Optical microscope images of as-grown 3R (left) and 2H CVD MoS2 bilayers (right) on SiO2/Si before pick-up. b First derivative of white light reflection spectrum for as-grown 2H-bilayer (blue) and as-grown 3R-bilayer (red), recorded at T = 4 K, both bilayers are encapsulated in high-quality hBN for optical spectroscopy29. c Schematic of 3R stacked bilayer with intralayer excitons (top) compared to 2H stacked bilayer where in addition interlayer excitons are observed as in panel (b).
