Graphene strongly interacts with photons, with the potential for direct band-gap creation. This is promising for optoelectronic and nanophotonic devices. Light interaction arises due to the Van Hove singularity. Graphene displays different time scales in response to photon interaction, ranging from femtoseconds (ultra-fast) to picoseconds.
Graphene doped with various gaseous species (both acceptors and donors) can be returned to an undoped state by gentle heating in vacuum. [22] [24] Even for dopant concentrations in excess of 10 12 cm −2 carrier mobility exhibits no observable change. [24] Graphene doped with potassium in ultra-high vacuum at low temperature can reduce ...

The Centre for Advanced 2D Materials (CA2DM), at the National University of Singapore (NUS), is the first centre in Asia dedicated to graphene research. [1] The centre was established under the scientific advice of two Nobel Laureates in physics – Prof Andre Geim and Prof Konstantin Novoselov - who won the 2010 Nobel Prize in Physics for their discovery of graphene.

Yuan Cao (Chinese: 曹原; pinyin: Cáo Yuán) is a Chinese electrical engineer and physicist.His research is focused on the properties of two-dimensional materials. [2] He discovered that a stack of two sheets of graphene, cooled to 1.7 K, could act as a superconductor or as an insulator when exposed to an electric field.
Graphene nanoribbons (GNRs, also called nano-graphene ribbons or nano-graphite ribbons) are strips of graphene with width less than 100 nm. Graphene ribbons were introduced as a theoretical model by Mitsutaka Fujita and coauthors to examine the edge and nanoscale size effect in graphene.
