Findings from Qingdao University Broaden Understanding of Chalcogens (Tunable periodic graphene antidot lattices fabricated by e-beam lithography and oxygen ion etching)

By a News Reporter-Staff News Editor at Life Science Weekly -- Research findings on Chalcogens are discussed in a new report. According to news reporting originating from Qingdao, People's Republic of China, by NewsRx correspondents, research stated, "Intrinsic monolayer graphene has no band gap between its conduction and valence bands, which limits its application in many aspects as a semiconductor."

Our news editors obtained a quote from the research from Qingdao University, "Antidot lattices by constructing periodic holes on graphene have been proved to be an intriguing strategy to introduce a band gap into graphene. Here we used the e-beam lithography (EBL) combined with the oxygen reactive ion etching (RIE) to fabricate tunable antidot lattices with different and uniform regularly spaced holes on graphene."

According to the news editors, the research concluded: "In this way, tunable periodic graphene nanostructures with the dimensions ranging from similar to 20 nm to several hundreds of nanometers can be fabricated by controlling exposure dose and etching time."
