Holey graphene as Holy Grail alternative to silicon chips

Graphene, in its regular form, does not offer an alternative to silicon chips for applications in nanoelectronics. It is known for its energy band structure, which leaves no energy gap and no magnetic effects. Graphene antidot ...

Slow 'hot electrons' could improve solar cell efficiency

Photons with energy higher than the band gap of the semiconductor absorbing them give rise to what are known as hot electrons. The extra energy in respect to the band gap is lost very fast, as it is converted into heat and ...

Nano-scale electronics score laboratory victory

Researchers at the NYU Tandon School of Engineering have pioneered a method for growing an atomic scale electronic material at the highest quality ever reported. In a paper published in Applied Physics Letters, Assistant ...

Graphene isn't the only Lego in the materials-science toy box

You may have heard of graphene, a sheet of pure carbon, one atom thick, that's all the rage in materials-science circles, and getting plenty of media hype as well. Reports have trumpeted graphene as an ultra-thin, super-strong, ...
