Thermal effects in artificial synapses

Ref. 2021_013


Considering that thermal design constraints are one of the most challenging problems for the microelectronics industry today, it comes as a surprise that so little is known about heat generation and dissipation on the nanoscale. To tackle these challenges, our team is developing new methods and tools for measuring temperature and heat transport down to the atomic scale. Our setups operate in IBM’s unique Noisefree Labs, which are among the best shielded nanotechnology labs in the world. Our work is of relevance for the development of next generation computers and scientific models. We help to identify future technologies, by evaluating new materials and device concepts from a thermal point of view.

The local heat generation in nanoscale devices has recently been explored as a means to trigger functionality. Heating can change the device resistance or trigger a specific time- response. Self-heated devices are now the major candidates for future neuromorphic computers, with an anticipated massive reduction in power consumption. However, our understanding of how materials properties, transport physics and device design should come together is still in its infancy. Measuring temperature fields at nanoscale resolution can help us explore those open questions and give insight into device working principles.


To address this, we are looking for a master student with a major in physics, electrical engineering, mechanical engineering, materials science, or related field. The candidate will join a motivated and diverse team of researchers with different background working in the topical area and be able to access world-class research infrastructure. You will have the opportunity to deal with several aspects of the experimental work, from the sample preparation in the cleanroom, to instrument control and data analysis. You will be supervised by Dr. Bernd Gotsmann and Nele Harnack.


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.
