Optical and tunneling spectroscopy of 2D material heterostructures
The aim of this project is to fabricate electrically controllable 2D-material devices in novel combinations that have not still been comprehensively investigated and conduct optical and electrical
spectroscopic studies.
The exploration of two-dimensional (2D) materials opened the door to a realm of fascinating electronic and optical properties [1]. Since the groundbreaking isolation of graphene, a myriad
of 2D materials, ranging from insulators to conductors and semiconductors, have emerged [2].
What makes these materials truly captivating is their facile isolation and the ability to stack them, creating heterostructures with intriguing properties. In our laboratory, we have an xpertise in 2D-material device fabrication as well as in optical and electrical characterization techniques. We focus on the development of light-emitting tunnel junctions, revealing unexpected behaviors that defy conventional understanding [3].
The aim of this project is to fabricate electrically controllable 2D-material devices in novel combinations that have not still been comprehensively investigated and conduct optical and electrical spectroscopic studies. Throughout the project, you will gain hands-on experience in device fabrication and become adept at utilizing diverse experimental setups both in ambient and cryogenic conditions. In that way, you will actively contribute into our ongoing research on 2D-material heterostructures, potentially leading to groundbreaking discoveries.

Prerequisites:
Fundamental understanding of solid-state physics and optics with a keen interest in
fabrication, spectroscopy and experimental techniques is crucial. We’re seeking for a critical and
independent thinker who wants to contribute to the collaborative research efforts of our dynamic
team.
