Quantized heat transport on the molecular scale

Ref. 2023_001

Background

Heat dissipation is one of the main limiting factors for present and future technologies. Understanding and controlling energy transport at the nano and molecular scale from room to cryogenic temperature, is of fundamental importance for novel applications, from quantum computers and neuromorphic chips, to new thermoelectric converters. For instance whereas good thermal conductors are needed in computing to remove dissipated heat poor thermal conductors are suited for energy conversion. Experiments are required to validate existing theoretical physical models and to gain insight into the structure property relationship at the nanometer scale. For these reasons, we have built a new experimental setup, based on a custom UHV Scanning Tunnelling Microscope, located in the superior IBM Noise free Labs.

PhD project

This PhD project focuses on measuring heat and charge transport at variable temperature in molecular and single atom junctions. The candidate will have the opportunity to deal with several aspects of the experimental work from sample preparation to instrument control and data analysis. The work seeks to understand the rich transport physics on the molecular scale, such as localization and quantization effects of entropy flow, using custom-designed ultra-sensitive thermometers. The candidate will join the Physical and Science of Information IBM Research Europe - Zurich and will be directly supervised by Dr. Bernd Gotsmann.
The successful candidate will have access to a laboratory fully equipped for the characterization of nanoelectronic devices at high precision. Furthermore, a fully equipped, state-of-the-art clean room is available for sample fabrication. This position is available for a duration of three years in a collaborative and creative group in a lively research environment.

Requirements

Applicants are expected to hold a Master’s degree in physics or engineering with a background in nanometer-scale physics. The ideal candidate enjoys the creative aspects of research, is highly motivated and is open to working in an international, multidisciplinary team.

Diversity

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.
