Researchers at Northwestern University have developed a new method for altering graphene, which could allow for faster creation of thin, flexible electronics.
The team found a new way to oxidise the material without damaging it as previous methods do. The resulting graphene oxide is chemically homogenous and reversible, enabling well controlled properties that can likely be exploited in high performance applications. The researchers leaked oxygen gas into an ultra high vacuum chamber. Inside, a hot tungsten filament was heated to 1500°C, causing the oxygen molecules to dissociate into atomic oxygen, reports the website Eureka.
Measurements showed that the electronic properties of the graphene varied as a function of oxygen coverage, suggesting that this approach can tune the properties of graphene based devices.
