Nano Vanadium dioxide: revolutionary material for electronics
The first is the switch. And then the transistor. Now, another innovation will revolutionize the way we control the flow of electrons through circuits: Nano vanadium dioxide (VO2). A key characteristic of the compound is that it behaves as an insulator at room temperature but as a conductor at temperatures above 68 ° c. This behavior also known as metal-insulator conversion.Scientists have long known about VO2's electronic properties, It turns out that its atomic structure changes with temperature, changing from a crystalline structure at room temperature to a metallic structure at temperatures above 68°C. This happens in less than a nanosecond -- a real advantage for electronic applications.
Unlocking the full potential of VO2 has been tricky, because the conversion temperature of 68°C is too low for modern electronics, where the circuits must be able to operate perfectly at 100°C. Swiss researchers raised the temperature of vanadium dioxide's phase transition to more than 100°C by adding germanium material to the VO2 film.
