Rice team modifies its Flash Graphene process to produce doped graphene

The Rice lab of professor James Tour has modified its flash Joule heating process to produce doped graphene that tailors the material’s properties for optical and electronic devices. The modified process shows how graphene can be doped with a single element or with pairs or trios of elements. The process was demonstrated with single elements boron, nitrogen, oxygen, phosphorus and sulfur, a two-element combination of boron and nitrogen, and a three-element mix of boron, nitrogen and sulfur.
