Kavli Institute of Nanoscience shines light on atomic transistor

16 November 2006 by TNWToday | M&C

Researchers Sellier, Lansbergen, Caro and Rogge of TU Delft''s Kavli Institute of Nanoscience and the FOM Foundation have successfully managed to measure a single dopant atom in an actual semi-conducting environment.

The researchers, who work in the Photonic Devices, transported a charge through one atom. Moreover, they successfully measured and manipulated the quantum mechanical behaviour of a single dopant atom. They were able for example to place one or two electrons in a particular shell of the atom.

This research provides the industry with greater insights into the (quantum mechanical) behaviour of transitions on the nano level. The individual behaviour of dopant atoms is a stumbling block to the further miniaturisation of electronics. The researchers have published their findings in the Physical Review Letters.
