The new transistor design, developed by Cambridge University experts Sungsik Lee and Nathan Arokia, will allow electronic devices to operate for months or even years with negligible power consumption or even no batteries.
In their development, scientists used an analogy with a faulty tap from which water is dripping. It is the "leakage" of energy that is the main problem of all transistors. Researchers have been able to identify how these leaks can be exploited.
The clue was the Schottky barrier - the place of contact between the metal and the semiconductor, which has a blocking property. Thanks to this barrier, it was possible to create a transistor operating on leakage energy.
“We have established, ” explains Nathan Arokia, “that the Schottky barrier makes it possible to create elements with ideal characteristics for extremely low power electronic devices, which are the subject of our research. These include wearable or implantable health monitoring electronics. This will allow, for example, to use the energy of a conventional AA battery (finger) for billions of years. "
Scientists see specific applications for new transistors in the Internet of Things, as well as devices that practically do not need to be recharged or connected to the network.
