Graphene nanoribbons grow due to domino-like effect

(PhysOrg.com) -- While many labs are trying to efficiently synthesize large two-dimensional sheets of graphene, a team of researchers from Sweden and the UK is investigating the synthesis of very thin strips of graphene just ...

Solving the solar cell power conversion dilemma

(PhysOrg.com) -- "There is a lot of interest in creating more efficient solar cells that are also simpler than many of the designs common now," Wladek Walukiewicz tells PhysOrg.com. "We think that, through the mixing of certain ...

Enhanced efficiency when determining band gap in solids

(PhysOrg.com) -- "With density functional theory, we are able to put different elements in a computer simulation and do calculations based on quantum mechanics to find out about their different properties," Maria Chan tells ...

Damaging graphene to create a band gap

(PhysOrg.com) -- "Graphene offers a lot of interesting potential applications for nanoelectronics," Florian Banhart tells PhysOrg.com, "but there is no band gap. This is a well-known problem. Without the band gap, switching ...

Toward a better understanding of bilayer graphene

(PhysOrg.com) -- "Graphene is a very exciting material with a number of interesting possibilities, including for use in electronic devices," Pablo Jarillo-Herrero tells PhysOrg.com. "However, all graphene systems are electronically ...

Can graphene nanoribbons replace silicon?
