Thermoelectricity converts heat into electric energy silently, directly and reliably. Facing limited reserves in fossil fuels, increasing greenhouse effect and constantly rising demand in energy, recovering heat losses can be a solution. Good thermoelectric material integrates: high electrical (¿) and low thermal (¿) conductivities. Conventional thermoelectrics are harmful, complex, expensive and industrially incompatible. In contrast, Silicon (Si), Germanium (Ge) and Silicon-Germanium (SiGe), are simple, easy-to-get, cheap and industrially compatible offering a high ¿. However, their usage in thermoelectricity is hindered due to a too high ¿. Recent progress in nano-fabrication opened possibilities to reduce ¿ with minor impact on ¿. This opportunity enables fabrication of CMOS compatible ThermoElectric Generators (TEGs) enabling massive production and cost reduction. Modelling approach place Si, Ge and SiGe in a competitive position compared with conventional thermoelectrics providing that their high ¿ is reduced. In this work, a 3-fold size induced ¿ reduction in Si is experimentally observed using platform that has been designed, fabricated and characterized in this work.
