Russian-born scientists Andre Geim and Konstantin Novoselov will share the 2010 Nobel Prize for physics for experiments with super-thin carbon matter.
In making the announcement on Tuesday, the prize committee said the two had shown that carbon in an extremely thin form - just one atom thick - had exceptional properties originating in the world of quantum physics.
The two scientists work at the University of Manchester, Reuters reports.
Andre Geim's Nobel prize comes ten years after he won an Ignobel prize for a 1997 experiment in which he levitated a frog using a magnetic field.
He says he is very proud of both.
The prize of 10 million Swedish crowns, awarded by the Nobel Committee for Physics at the Royal Swedish Academy of Sciences, was the second of this year's Nobel prizes.
