The thing with graphene transistors
Graphene is one of the hottest research areas in nanotechnology, and it may seem slightly surprising it took me a month to write my first blog post on the topic. That moment has now come, with the...

Yet more graphene transistors – it’s twins!
Last week I blogged about a Nature paper on graphene transistors with a self-aligned nanowire gate. Well, as I gather from a blog post by Doug Natelson, largely the same UCLA researchers have now...

The air is getting thinner for silicon’s competitors
Intel's 3D tri-gate transistors have a feature size of only 22 nm. The thin structures are the silicon channels, the thicker ones are the gates and the contacts. Several gates can be used next to each...

Transistors reach the single atom limit
A scanning tunnelling microscope image of a single-atom transistor during fabrication. The pink colours represent the areas where a single phosphorus atom (centre) as well as phosphorus source and...
