16. Thermoelectric- and hot-electron effects in graphene devices
Abstract : A technology of encapsulation of graphene in Parylene was introducedas an alternative to encapsulating graphene in hBN. Edge contacts to theencapsulated graphene in this case showed resistivity down to 14 Ohm um,which is the lowest reported value so far. READ MORE

17. Thermoelectric Phenomena in Quantum Dots
Abstract : Thermoelectricity is being intensively researched as it is believed to hold great promise for applications in power generation and cooling. One way to quantify the electrical power output of a thermoelectric material is the power factor, a function of electrical conductivity and thermopower. READ MORE

19. Nanostructured Bulk Thermoelectrics : Scalable Fabrication Routes, Processing and Evaluation
Abstract : Current fossil fuel based energy sources have a huge shortcoming when one discusses their efficiency. The conversion efficiency of fossil fuel-based technologies is less than 40% in best cases. READ MORE

20. Hot-carrier extraction in nanowires
Abstract : A hot-carrier solar cell aims to generate power from energetic, photoexcited, charge carriers, so called hot carriers, in order to reach higher conversion efficiencies than current solar cell technology.Creating a hot-carrier solar cell has proven challenging for two main reasons: hot carriers lose their energy very quickly, and they need to be extracted over distances of a few hundrednanometers via energy selective filters.
