Fundamental properties of 2D materials and novel device architectures
Here, we explore the exciting wealth of physics made possible by the extreme tunability and unique form factor of 2D materials, and how this can be turned into devices
These include bandgap engineering using 10-nm scale nanopatterning, moiré-superlattices, and curvature engineering of graphene and other 2D materials.
In 2DEM we explore the unique properties of low-dimensional materials and how these can be engineered towards novel types of devices and technology, mainly within electronic and optoelectronic application areas.
We also look for routes towards high-temperature superconductivity, ferroelectric switching, and phase transformation in transition metal dichalcogenides.
Electron transport in 2D materials can be enhanced by ballistic transport and exotic effects such as electron focusing and Klein tunnelling. We also look into how such “beyond-field-effect” principles can be harnessed. A recent area of interest is light-wave physics, in which ultrashort pulses of light (i.e. THz pulses) are used to drive, manipulate, and probe electrons and phases at ultrahigh frequencies in collaboration with Prof. Peter Uhd Jepsen at DTU Fotonik.
Large scale 2D material characterisation and integration
We work on solving problems and removing roadblocks for large-scale graphene applications (mainly electronics), such as large scale growth, encapsulation, characterisation and patterning, in collaboration with the Applied 2D Materials group.
We develop large-scale heterostructures where the properties of pristine 2D materials are protected against doping, scattering and outside influences, using scalable methods inspired by our hot-pickup vdW assembly method.
Since 2012, we collaborated with DTU Fotonik to establish a large-scale THz-TDS mapping technique for graphene that offers fast and accurate quality control, mobility, and carried density mapping, as well as deeper insights into carrier dynamics and microstructure, which became one of the first graphene metrology standards in 2022.
We are also interested in graphene and other 2D materials, such as chemical barriers, membranes, and coatings.
