Wet etching of gold on graphene for high-quality resist-free graphene surfaces
Wet etching of gold on graphene is challenging due to the weak adhesion of the resist mask to graphene.We report an operating procedure for alkali ion-free wet etching of gold on graphene using a mixture of hydrochloric and nitric acids (aqua regia) with a high lateral resolution down to 100 nm.We investigate Rangehood Filter Material the role of p
