PhD position in ab initio electronic transport simulations

100%, Zurich, fixed-term

The Computational Nanoelectronics Group (www.nano-tcad.ethz.ch) at the Integrated Systems Laboratory (www.iis.ee.ethz.ch) of ETH Zurich is developing and applying advanced simulation tools to investigate the properties of nanoscale devices. For a research project funded by the Swiss National Science Foundation (SNSF), we are looking for one PhD student in ab initio electronic transport simulations.

 

Project background

Semiconductor microprocessors build the core of all electronic devices, from laptops, cell phones, or tablets to vehicles and automated systems. Besides the end of Moore’s scaling law, the development of future chips face other challenges such as the introduction of new functionalities to devices whose dimensions do not exceed few nanometers. For example, ultra-scaled transistors, the active components of all microprocessors, might soon be combined with photo-emitters, modulators, and receivers to enable optical communication within or between chips. Nanoscale thermoelectric generators and coolers could also come into play to either recycle part of the heat dissipated by the chips or to remove it from their active area. On the one hand, new materials will have to be integrated with silicon, the semiconductor of reference, to support these innovations. On the other hand, the atomic size of the resulting structures will give rise to strong electrical, thermal, and optical effects that intrinsically depend on each other. Altogether, this makes the conception of next-generation nano-devices extremely complex, thus calling for the emergence of novel design approaches.

Job description

In this PhD thesis, a novel ab initio quantum transport solver will be developed to address these issues. It will take advantage of the always increasing computational power to offer physical models of greater accuracy than the existing ones. The focus will be on electronic transport and the interplay of electrons with other carriers, phonons, and photons. All these effects will be captured at the quantum mechanical level and from first-principles. To be able to leverage the already available exascale computing resources, a dedicated parallel programming model called DaCe will be exploited. It allows to express computations separately from data movements and automatically generates hardware-specific codes from programs written in a high-level scripting language, Python in the present case. The main task of this PhD thesis will therefore be to implement the required physical modules in Python, validate them, and apply them to the simulation of nanoscale devices. This work will be performed in close collaboration with other PhD students and post-docs who will concentrate on different aspects of this SNSF project.

Your profile

You should have a Diploma or Master's degree in electrical engineering, physics, material science, computational chemistry or in a related discipline, excellent Python programming skills, a strong background in quantum transport theory, and interest in physics-based device modelling. Experience with density functional theory is a plus.
