PhD position in vibrational and optoelectronic properties of quasi-1D chalcogenides
Investigate the optical and electronic properties of quasi-1D chalcogenide semiconductors in a collaborative research environment.
Best for:Best for candidates with a background in physics, materials science, or nanoscience and a strong interest in optical spectroscopy and quantum materials.
Overview
The Nanomaterials Spectroscopy and Imaging Group at Empa is seeking a PhD student to study the vibrational and optoelectronic properties of quasi-1D (Ba,Sr)(Ti,Nb,Ta)(S,Se)3 chalcogenides. This project focuses on understanding how material composition, defects, and chain alignment influence collective electronic phenomena like charge-density-wave order. The successful candidate will utilize advanced optical and time-resolved spectroscopic techniques to analyze single crystals and thin films. This position is part of a collaborative project with FAU Erlangen-Nürnberg, funded by the Swiss National Science Foundation (SNF) and the German Research Foundation (DPG).
What you'll do
- Conduct polarization- and temperature-dependent Raman and photoluminescence spectroscopy on quasi-1D chalcogenides.
- Characterize carrier dynamics using time-resolved photoluminescence, terahertz spectroscopy, and transient absorption.
- Develop and implement data-analysis workflows to correlate findings from multiple characterization techniques.
- Collaborate with synthesis, theory, and device research partners.
- Disseminate research findings through peer-reviewed publications and international conference presentations.
Requirements
Degree required: Master's degree in physics, materials science, chemistry, nanoscience, or a closely related field.
Degree offered: PhD
Language: Excellent written and spoken English.
Instruction: English
- Strong interest in optical spectroscopy and semiconductor physics.
- Proficiency in quantitative data analysis.
- Programming skills in Python or MATLAB.
- Ability to work independently and contribute to an interdisciplinary team.
- Willingness to collaborate across institutions and undertake a research stay abroad.
