Can you image charging your mobile phone by simply using your body heat? Thermoelectrics is all about transforming heat into useful energy<\/a>, mostly utilising inorganic materials. The thermoelectric effect is the direct conversion of temperature differences to an electric voltage and vice versa through a thermocouple.<\/p>\n Due to the mechanical flexibility, lightweight, and low thermal conductivity of organic semiconductors, they have been widely adopted as a promising material system especially for flexible thermoelectric applications.<\/p>\n Efficient doping for charge-carrier creation is key in thermoelectric device performance. Conventional bulk doping typically introduces disorder at high doping concentration, thus limiting the electrical conductivity.<\/p>\n \u201cIn our study, we employed the modulation-doping approach to highly ordered organic thin films, where the dopant impurity is separated from the conduction channel,\u201d explained first author, Dr Shu-Jen Wang, from the Institute of Applied Physics at TU Dresden<\/a>. \u201cWith this method, we are able to achieve highly efficient doping even at high doping densities without influencing the charge transport in the thin films.\u201d<\/p>\nEffective doping for charge-carrier creation<\/h3>\n
