Controllable double quantum dots and Klein tunneling in nanotubes

Researchers from the Kavli Institute of NanoScience in Delft are the first to have successfully captured a single electron in a highly tunable carbon nanotube double quantum dot. This was made possible by a new approach for producing ultraclean nanotubes. Moreover, the team of researchers, under the leadership of Spinoza winner Leo Kouwenhoven, discovered a new sort of tunneling as a result of which electrons can fly straight through obstacles. The results of the research were published by Nature Nanotechnology on April 5, 2009.
