Illustration of the transport phenomenon
Researchers of Aalto University in Finland and the German University of Marburg have collaborated in the study of the movement of charges over interfaces of semiconductor materials. The group noticed a new kind of transport phenomenon for charges. In the phenomenon, a pair formed by a negative electron and a positive charge moves onto an interface, after which its 'message' is passed on to the other side of the interface, where it is carried on by a similar pair. The new theoretical result opens up interesting prospects for carrying out logical operations in electronics.
In addition to microelectronics, transport phenomena of charges are in a key role in many biological processes, such as photosynthesis," explains Professor Ilkka Tittonen from Aalto University.
