- •
Polyvinyl alcohol (PVA) polymer is demonstrated as an efficient capping layer to improve the 2D device performance.
- •
Field-effect mobilities can be increased from 0.28 cm2/Vs to 269.2 cm2/Vs after applying the PVA capping layer.
- •
An energy band diagram based on Schottky barrier modulation is proposed to understand the device mechanism.
