Just one atom thick
In the 1960s, researchers envisioned that graphite (pure carbon) could be cut into layers measuring only one atom in thickness -- resulting in the material known as graphene.
In the 1990s, researchers managed to create a layer as thin as 100 atoms, but there was no progress after that until 2004, when Russian-born Andre Geim grabbed a tape dispenser from his desk at the University of Manchester, pressed a bit of tape over a thin layer of graphite and peeled it away. When he examined the tape under a microscope, he discovered a layer only one carbon atom thick. Graphene was born!
In 2010, Dr Geim and his colleague, Konstantin Novoselov, were jointly awarded the Nobel Prize in Physics for their work in demonstrating the unique properties of graphene.

lähes kymmenen vuotta sitten pistin tänne juttua sirujen koosta. silloin 0,4* 0,4 mm ja jo tuotannossa, joku japanilainen firma
sen sijaan vieläkin näytetään tätä 20 vuottqa vanhaa kuvaa microchipistä

To provide further miniaturization, Case Western Reserve University and Atotech will jointly explore the application of a metallization technology, called electroless deposition, for metalizing semiconductor features smaller than 22 nanometers.

totuus on atomi koko luokkaa, melkein kuin pölyä
