The etching and lift off process poses problems because of delamination and contamination due to polymer residues when using standard resists We introduce a metal etch mask which minimises these problems The high quality of graphene is shown by Raman and XPS spectroscopy as well as electrical measurements The patterning of graphene is of note as this step was found to be unreliable using conventional methods i e by the use of polymers as etch masks 7 8 In our experiments delamination of graphene occurred when
The commonly used patterning technique is selectively etching of unwanted regions of graphene using metal etch mask and then the removal of the metal via harmful acid treatment In this With patterning of these graphene layers using standard photoresist masks we are able to produce arrays of gated graphene devices with four point contacts The etching and lift off

1 Introduction Working with 2D materials such as graphene requires novel methods to fabricate ribbon patterns Among the traditional methods are a metallic or resist mask to selectively protect graphene in plasma etch exposure 1 5 and focused ion beam FIB etching 6 7 Here we report a one step facile method to pattern graphene by using stencil mask and oxygen plasma reactive ion etching RIE and subsequent polymer free direct transfer to flexible
Herein we present a simple low cost and scalable wet etching method for graphene patterning A phase shifting mask is used to modulate incident laser beam spatially and generate graphene patterns by laser heating Periodic graphene nanoribbon and nanomesh structures are fabricated by employing 1D
