Implementation and application of a thermal conductivity setup for nanocrystal thin films
In this project a setup should be implemented to measure the thermal conductivity in thin-films. This includes sample microfabrication, understanding and improving the setup and extending it to nanocrystal films.
Keywords: Material Science, Characterization, Thin-film, thermal conductivity, electrical measurement
In many device applications, such as in computer chips, solar cells, thermoelectrics or anti-reflective coatings the control of the thermal behavior of the materials involved is of essential importance to the performance of the device. In the case of nanostructured devices and thin-films measuring the thermal conductivity is non-trivial and requires indirect measurement methods, such as the 3 omega method, which can be used to obtain the thermal conductivity through electrical measurements.

In a previous semester project the groundwork for this project was laid down and a basic 3-omega measurement setup has been implemented. The goal of this project is to expand and improve the setup to be able to measure actual thin-films and consequently start measuring the thermal conductivity of different nanocrystal based thin-films for device applications.
The task
- Understand the electric measurement setup and implement improvements and changes.
- Learn the microfabrication methods required for sample production.
- Prove that the setup correctly measures thin-film thermal conductivity.
- Apply the methodology to nanocrystal thin films.
