Oxygen‐Assisted MOCVD Growth of Monolayer PtSe2 Films With Bandgap Opening for Semiconducting FET Channels

Advanced Science, EarlyView.
Monolayer PtSe2 films are successfully grown via optimized MOCVD, achieving uniform coverage over a 1.5 cm × 1.5 cm area. Oxygen‐assisted growth effectively removes carbon impurities, ensuring high film quality. Array‐level FETs based on monolayer PtSe2 channels demonstrate low off‐current and high ION/IOFF ratios, highlighting the potential of PtSe2 ...
