Single electron captured in nanotube quantum dot

Abstract:
Researchers at the Kavli Institute of NanoScience (Delft, the Netherlands) have captured a single electron in a highly tunable carbon nanotube double quantum dot. The researchers suggest they are the first to do this successfully.

The researchers used silicon electrodes positioned close to the ultraclean nanotube to control precisely the number of electrons of the quantum dot.



The breakthrough was made possible through a new approach for producing ultraclean nanotube quantum dots.

The team of researchers, led by Spinoza prize winner Leo Kouwenhoven, also say they discovered a new kind of tunneling as a result of which electrons can fly straight through obstacles.
