Article Synopsis
- Current graphene patterning techniques like electron beam lithography and nano imprint lithography are slow and less effective for larger samples, often resulting in rough edges and misalignment.
- This study introduces hot punching as a new and efficient method for patterning CVD graphene sheets supported by a PVA layer, allowing for the creation of nanoribbons.
- The effects of hot punching on the graphene are analyzed through various methods, showing improvements such as aligned and smoother edges, along with the occurrence of wrinkling and strain.
Nano- and microelectromechanical structures for in situ operation in a transmission electron microscope (TEM) were fabricated with a turnaround time of 20 min and a resolution better than 100 nm. The structures are defined by focused ion beam (FIB) milling in 135 nm thin membranes of single crystalline silicon extending over the edge of a pre-fabricated silicon microchip. Four-terminal resistance measurements of FIB-defined nanowires showed at least two orders of magnitude increase in resistivity compared to bulk.
