Thermal imaging of nanoscale devices with mK thermal and nm spatial resolution

We are looking for a highly motivated master student for our activities in devices for future computing applications using novel materials and effects. The candidate should be enrolled in physics, mechanical engineering, electrical engineering, materials science or a related field

Heat removal in current micro-electronic chips is one of the most critical challenges for future computing applications. The heat is generated at the device level and in wires of nanometer scale dimensions, and has to be transported to the heat spreader millimeters away. At the same time thermal transport properties change significantly when approaching nanometer scales, and boundary resistances take over thermal transport characteristics. Since many of these parameters are unknown, simulations cannot reliably be established and a strong need for experimental data exists. Here at IBM, we work on Scanning Thermal Microscopy (SThM) with active devices. Using those, we have developed self-sensing techniques to quantify heat transport through films and interfaces down to nm-scales [1,2]. The technology has demonstrated < 10 nm and < 0.1 K resolution, perfectly suited to address many of the material’s thermal properties at the nanoscale. In this project we will measure first material systems as a function of dimensions and develop first thermal models for the observed effects.

Benefits of carrying out a master project at IBM: IBM Research Europe – Zurich (IBM) is a leading research laboratory for cutting-edge research in nanotechnology and information technologies with a strong track record of fundamental and applied research. In addition to excellent research facilities at IBM, our group offers an open and cooperative work environment. IBM is committed to diversity at the workplace. With us, you will find an open, multicultural environment. Excellent, flexible working arrangements enable all genders to strike the desired balance between their professional development and their personal lives.

Diversity & Work Environment

IBM is committed to fostering diversity and inclusion in the workplace. You will join an open, multicultural research environment that values different perspectives and supports flexible working arrangements. Our goal is to help all genders and backgrounds thrive professionally while maintaining a healthy work–life balance.
