Our concept is based on deep understanding of the behaviour of phonons, their control leading to the control of thermal transport. It targets minimizing the thermal conductance and or thermal conductivity by phonon engineering.
A test device will be produced thanks to technologies combining Si microelectronics, thin film thermoelectric material and novel concepts to understand heat transport in 2-dimensional nanostructured materials such as Si-based ultrathin membranes, GeMn and strontium titanate.
The methods and technologies developed will enable nm-scale control of energy generation and heat flow. This will impact on on-chip and in-package energy management that is of crucial importance for future technologies. Especially, our targets contribute to (a) on-chip harvesting of thermoelectricity and (b) management of heat flow in the applications of heterogeneous integration and nanoelectronics.
