Spletstudy the air-tightness of the hBN encapsulation method, the most common passivation method for a wide range of 2D material-based devices. We find that only fully encapsulated devices are reliably air-tight. On the contrary, a simple hBN cover from the top does not prevent a slow diffusion of oxygen between the SiO 2 surface and the flake ... Splet23. nov. 2015 · The thermal expansion of PDMS enables the softened PMMA to completely confirm to the shape of the thick h -BN flakes at 90 °C, thus ensuring the firm contact between graphene and target h -BN.
