1. 1. Synthesis of Nanostructured Silicon - Germanium Thermoelectric Materials by Mechanical Alloying

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Mohammad Shafiullah; [2015]
   Keywords : ;

   Abstract : Silicon-germanium (SiGe) thermoelectric material is especially suited in power generation operating above 700 °C to 1000 °C to convert heat into electricity. Traditional bulk SiGe alloy thermoelectric materials has the value of dimensionless thermoelectric figure of merit (ZT) at maximum about 0.93 at 900 °C. READ MORE

4. 3. Thermoelectrical Characterization of Organic Materials

   University essay from Institutionen för teknik och naturvetenskap

   Author : Abdellah Malti; [2009]
   Keywords : thermoelectrics; thermogenerators; n-type organic materials; TDAE doping;

   Abstract : Organic semiconductors are prime candidates for thermoelectric applications, because one can maximize the dimensionless figure of merit ZT (by maximizing the Seebeck coefficient and electrical conductivity) while simultaneously minimizing the thermal conductivity. In this work, we explore a few materials and try to find their thermoelectric characteristics. READ MORE
