In brief, the Chalmers team has demonstrated fabrication of micro energy storage units called Microsupercapacitors, with enhanced performance by utilization up to four different materials (composites of graphene oxide), all layered through the same fabrication process i.e. spin coating.
The Chalmers team from the Excellence Initiative Nano at Chalmers University will organise a webinar about “Scalable fabrication of edge contacts to 2D materials”, on 02 May 2022 at 15:00 CEST.
Naveen Shetty, PhD student at the Quantum Device Physics laboratory at the Department of Microtechnology and Nanoscience (MC2), will give a talk which will be divided into two parts: (i) pure overview of the field, accessible for all audience (15 min); (ii) his latest technical results, for a more specialised audience (15-20 min).

Abstract: The performance and reliability of electronic devices based on 2D materials crucially depends on the quality of electrical contacts. However, the problem of electrical interfacing 2D materials remains relatively overlooked, and the fabrication of reliable and reproducible ohmic contacts to a variety of 2D materials remains somewhat an open challenge. In this talk I’ll present a fabrication method for reliably producing wafer-scale electrical contacts to 2D materials, including graphene and transition metal dichalcogenides (TMDCs). While demonstrated for 2D materials, our method of forming electrical contacts to 2D materials could be in principle useful for other low dimensional systems, bulk crystals, and organic semiconductors. I will discuss a few possibilities during my talk.

The sun provides our planet with an abundance of energy in the form of solar light – a continuous stream of light particles, so called photons. The sunlight contains a broad spectrum of photon energies, but only a fraction of the photon energies can be harvested efficiently by a solar energy device. Photon energy conversion techniques provide a way to increase the efficiency of solar energy technologies by converting incoming photons of too high or too low energy to photons with energy that can be harvested efficiently by the solar energy device. In this talk I will present the basic ideas behind photon upconversion by triplet-triplet annihilation and photon down-conversion by singlet fission, as well as showing some of the latest results from our research group.
In a compact comment published in Nature Communications, Max Lemme - CEO at AMO GmbH and Professor at RWTH Aachen University - and his colleagues outline the most promising fields of applications of two-dimensional (2D) materials, as well as the challenges that still need to be solved to see the appearance of high-tech products enabled by 2D-materials.
