Ph.D. student for thermoelectric modules : Technical University, Denmark

Thermoelectric materials can convert heat directly into electricity without moving parts. A thermoelectric module (TE) consists of at least two different materials. A major part of the losses in such modules is associated with the contacts and interfaces between the materials.
 
DTU Energy Conversion, the Section for Electro-Functional Materials, is now seeking a motivated Ph.D student to study the evolution of contacts and interfaces in thermoelectric modules.
 
Job description
You will be part of a large national project on Center for Thermoelectric Energy Conversion with partners from both universities and industry. The successful candidate will have the opportunity to work also closely with TEGnology A/S, a dynamic and active company which develops thermoelectric generators for medium range temperature applications.
 
In this project, the PhD will identify and measure the contact resistances of TE legs and electrodes over extended periods of time under different atmospheres. The kinetics of the interface will be studied by imaging and analytical techniques. Different possible contact materials e.g. metals or alloys, as well as joining methods will be considered and investigated in order to further minimize the internal resistances of the modules to maximize the power output. The results of the contact resistance measurements will be incorporated with numerical modeling to identify the possible ways to improve the module performance.
 
Qualifications
 
Master’s degree in chemistry, physics, materials science or similar
Good knowledge of solid state physics and thermodynamics
Experience with experimental methods for materials processing and characterization
Preferably familiarity with multi-physics programs for simulations, e.g. COMSOL
Ability to work independently, to plan and carry out complicated tasks, and to be a part of a large, dynamical group
Good communication skills in English, both written and spoken
