2. Frontiers of thermoelectrics in semiconductor quantum wires: Contact person: Francesco Rossella Fabio Taddei This activity focuses on the demonstration of device and heater architectures to establish a very large thermal gradient (e.g. several K/μm) while allowing to control the nanostructure electronic configuration by field effect. Work is in progress for the development of novel opto-electronic methods for the determination of the thermal conductivity of single wires and for the estimation of the ZT factor of nanomaterials. Future perspectives include the investigation of quantum confinement effect on the thermoelectric effects (energy conversion and/or cooling) in devices based on nanowires whose electronic properties are strongly modified by multi-pole gating and by using heterostructures.
