“With 60 GHz you can only communicate across short differences and not through walls, for instance.
The hope is to reach 60 GHz, which is a considerably broader frequency range. Today’s electric appliances use 3–10 gigahertz. Ultimately Lars-Erik Wernersson and his colleagues also hope to develop transistors that can communicate in entirely new frequency areas. According to Lars-Erik Wernersson, this means that the material is self-organized according to a bottom-up principle instead of being “carved out,” which is the conventional method. The transistor is thus constructed using nanotechnology. Actually, it’s hard to produce transistors with indium arsenide, but if we apply nanotechnology, it’s rather simple,” explains Lars-Erik Wernersson. “But our model is made up of indium arsenide, where the electrons move more easily compared with silicon, the conventional semiconductor material in transistors. What’s more, it can pave the way for communicating in frequencies that are too high for today’s technology,” says Lars-Erik Wernersson, professor of solid state physics at the Faculty of Engineering, Lund University, in Sweden.įor some time researchers have been stymied by the fact that transistors can’t be reduced any further in size without overheating, since the electrons release so much energy. “This kind of transistor should be able to reduce energy consumption in mobile phones and computers, for example, so they wouldn’t have to be recharged so often.
