BSTRACTWe report on the structural

chemical and electrical compatibility of graphene in an alkaline environment

namely diluted KOH solutions as those used in standard nanofabrication methods. Electron microscopy and Raman spectroscopy indicate that graphene preserves its structural properties during the process. The electrical transport properties such as conductance and shape of the Dirac point

appear degraded after KOH treatment

but can be fully recovered by current annealing. Electron beam-induced etching can provide further nanofabrication subsequent to KOH processing. These results demonstrate that

with the due precautions

graphene-based structures can be integrated in standard fabrication processes involving KOH.
