About

The 2DPHYS section focus on advanced functional materials such as 2D materials, ferroelectric materials and metamaterials, and how to synthesize them and how their properties can be engineered to create a platform for new technology within electronics, optics, energy and biology. The section has three theoretical (PI’s: Mads Brandbyge, Antti-Pekka Jauho and Simone Latini) and five experimental groups (PI’s: Tim Booth, Abhay Shivayogimath, Søren Raza, Hugh Simons and Peter Bøggild).

On the theory side, numerical simulations using time-independent and time-dependent DFT and multiscale- and hybrid tight binding methods are used to design, analyse, and understand electronic quantum transport in realistic molecular and nanoscale 2D devices, to understand ultrafast time-dependent material properties and the behavior of phonons and excitons in nanomaterials and nanostructures, and learn how to control the phases of nanomaterials using optical or electrical stimulation.

Experimentally, we fabricate two-dimensional materials such as graphene and transition metal dichalcogenides, assembly these into heterostructures, and shape these into sophisticated devices using state-of-the-art fabrication and nanopatterning tools. The nanoscale shape of materials is of great interest to us. We want to understand the underlying mechanisms of ferroelectric/electroactive materials and control their properties, enhance the electric tunability of semiconducting 2D materials through strong coupling, create novel type of ultrasensitive magnetic sensors for detection of neuronal currents and manipulate the transport properties of 2D materials: electron transport through bandgap, dielectric and excitonic engineering, all the way to liquid transport through creation of narrow liquid channels and pores.

We have our excellent lab facilities, with 2DTU - our “cleanroom-in-a-glovebox” environment (nanolithography, etching, metal deposition, van der Waals assembly) at the core. Here we work with large-scale 2D materials from synthesis, transfer, integration and prototyping, to mechanically exfoliated nanomaterials and assemble complex heterostructures for high-performance prototyping and experimental device architectures. The glove-box environment allow us to fabricate devices from air-sensitive materials, and with far less contamination. We are also heavy users of DTU Nanolab – the National Centre for Nano Fabrication and Characterisation, a state-of-the-art class 10 cleanroom facility with outstanding nanofabrication and nanolithography equipment, as well as a dedicated center for electron nanoscopy with 2 FEI Titan transmission electron microscopes.

The Section is located in Building 309, where the foundation stone for the DTU Lyngby campus was laid. The section head is Professor Peter Bøggild (pbog@dtu.dk)
