Postdoctoral Research Position: Electronic Properties of van der Waals Heterostructures (M/F)

Job Description

Missions

Van der Waals heterostructures are a promising platform for studying and engineering electronic properties in quantum materials. By stacking different two-dimensional (2D) materials, it is possible to create systems with new and tunable properties.

In these heterostructures, the electronic properties are strongly affected by interactions at the interfaces between layers. Charge transfer between materials can modify the electronic density and create new electronic states. In addition, hybridization between electronic states from different layers can significantly change the electronic band structure and lead to new physical phenomena.

In this postdoctoral project, we will investigate the electronic properties of van der Waals heterostructures, with a focus on interface interactions, charge transfer, and electronic hybridization. The goal is to understand how these mechanisms influence the band structure and the physical properties of 2D materials. The project will combine electronic spectroscopy with complementary characterization techniques, including electronic transport, microscopy, and optical spectroscopy, to establish links between electronic structure and emerging physical properties.

Activity

Design and perform optical and electronic characterization of two-dimensional materials and their van der Waals heterostructures to investigate their electronic, optical, and excitonic properties.
Implement optical spectroscopy techniques, including photoluminescence (PL), Raman spectroscopy, and temperature-dependent photoluminescence, as well as band structure characterization techniques for two-dimensional materials.
Analyze and interpret experimental data to investigate quantum confinement effects, charge transfer, interfacial interactions, and electronic hybridization in van der Waals heterostructures.
Supervise Ph.D. candidates, Master's students, and interns while overseeing experimental activities, data analysis, and the development of new experimental methodologies.
Collaborate closely with project partners to compare experimental observations with theoretical models and establish correlations between the electronic structure, optical properties, and emerging physical phenomena.
Disseminate research findings through publications in peer-reviewed international journals, presentations at national and international conferences, and active participation in scientific outreach activities.
