The main goal of this project is to exploit the peculiar physics of a class of topological material, the Weyl semimetals, for new electrical devices. These materials, due to their unusual band structure (which is gapped except at some isolated points, called Weyl nodes) have been shown to exhibit interesting properties like a huge magneto-resistance at cryogenic temperatures, and a set of different transport mechanisms that can be exploited for several purposes. Applications-wise, the focus of this work is on two possible device implementations: a Weyl semimetal amplifier and an oscillator. These two device concepts are designed to work under low power and cryogenic conditions, which make them highly suitable for quantum-computing applications.
