 ReSe2 monolayers do not contain intentional dopants or defects. However, our technical staff can produce defected ReSe2 using α-bombardment technique.

 

 

 

Supporting datasets [for 100% Full area ReSe2 monolayers on c-cut Sapphire]

Transmission electron images (TEM) and angle resolved Raman spectroscopy measurements acquired from CVD grown full area coverage ReSe2 monolayers on c-cut sapphire confirming crystalline anisotropy

Energy dispersive X-ray spectroscopy (EDX) characterization on CVD grown full area coverage monolayer ReSe2 on c-cut sapphire

Raman spectroscopy measurement confirm monolayer nature of the CVD grown samples. Differential reflectance measurements clearly show band gap at 1.45 eV for monolayer ReS2 consistent with the existing literature values. PL spectrum does not show any PL signal due to indirect band nature.
