1. Waste-heat Recovery Using Thermoelectricity and Silicon Carbide Power Electronics
Sammanfattning : Energy consumption in the world has increased continuously due to a growing population and increased energy consumption per capita. Moreover, the largest part of consumed energy still comes from fossil sources which in 2016 was more than 130 PWh. LÄS MER
2. Study the Influence of Quantum Interference on the Electrical Conductance and Thermoelectric Properties of Molecular Junctions : Synthesis and Thermoelectricity
Sammanfattning : This thesis mainly describes our efforts towards the study of the quantum interference of electronic conductance and thermoelectric properties in molecular junctions. Chapter 1 introduces the concepts of the charge transport in single-molecule junctions, include the electrical conductivity and thermopower which are the main parameters to assess the efficiency of the single-molecule junctions.

3. Thermoelectric Devices with Electronic and Ionic Conducting Polymers
Sammanfattning : The energy consumption in the world is continuously growing and the sources of energy are largely dominated by fossil fuels. However, the resources of oil, gas and coal are diminishing in capacity. Moreover the CO2 emissions arising from their combustion is a great concern because it induces climate changes that threaten our habitat. LÄS MER
4. Thermoelectric Phenomena in Quantum Dots
Sammanfattning : 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. LÄS MER
5. Synthesis and Characterization of New Inorganic Thermoelectric Materials
Sammanfattning : With thermoelectric materials it is possible to convert a difference in temperature into electrical energy. This can be utilized for a more efficient use of available energy, eg. by converting waste heat from a combustion process. LÄS MER
