Abstract
Changes in properties of graphene grown by chemical vapor deposition (CVD) with water adsorbate removal from the graphene–SiO2/Si substrate interface using an organic material, i.e., acetone, are studied. It is found that acetone vapor suppresses grapheme structuring under low-intensity nanosecond laser radiation (wavelength λ = 532 nm). It is found that the electron work function in graphene decreases by ∼0.2 eV, which is presumably due to a decrease in the water adsorbate layer thickness at the mentioned interface.
