Master Thesis in Physics or Materials Science - Atomic-Scale Study of 2D van der Waals Heterostructures Using STM

Novel low-dimensional electronics are the key to future sustainable information technologies. At the Peter Grünberg Institute - Electronic Materials (PGI-7), we develop hardwares for energy-efficient AI and Neuromorphic computing. Two-dimensional (2D) materials, such as graphene and hexagonal boron nitride (h-BN), are among the most promising platforms for next-generation nanoelectronics and quantum technologies due to their exceptional electronic properties and atomically confined interfaces. Understanding atomic-scale stacking, defects, grain boundaries, and edge structures is essential for designing future 2D heterostructure devices.

Your Job

In this thesis project, the project focuses on the atomic-scale characterization of graphene-based van der Waals heterostructures using low-temperature scanning tunneling microscopy and spectroscopy (LT-STM/STS) at 5K. We will directly visualize atomic structures and probe the local electronic states of low-dimensional materials with atomic-scale spatial resolution. This master thesis offers the opportunity to investigate graphene-based van der Waals heterostructures at the atomic scale, providing fundamental insights into the relationship between crystal structure and electronic properties.

In this project, your tasks will be to further investigate monolayer h-BN/graphene and graphene/graphene heterostructures:

Atomic structure and stacking configuration
Defects and grain boundaries
Edge termination (zigzag and armchair)
Local electronic structures (LDOS)

The student will gain hands-on experience in ultra-high vacuum (UHV) operation, LT-STM/STS measurements, and the analysis of atomic-resolution structural and spectroscopic data.
