Abstract

Carbon-based materials belong to the emerging quantum materials that bear a strong promise for applications in quantum technology. The lecture will provide a broad insight into nanoscale carbon-based materials, from their fundamental opto-electronic properties to their implementation in practical devices. We will first discuss the electronic properties of carbon-based materials, focusing on low-dimensionality systems, starting from short molecules that can be seen as 0D quantum dots, to graphene, a 2D material with remarkable mechanical, electrical and optical properties. The experimental techniques to fabricate and electronically characterize such systems will then be addressed and their electronic transport properties discussed. Finally, we will extend the discussion to practical devices such as ion-sensing field-effect transistors.
