Two dimensional (2D) materials such as graphene, black phosphorous, and transition metal dichalcogenides (TMDs) exhibit fascinating physical properties due to their specific band structure and reduced dimensionality. In recent years, TMDs (MX2, where M = Mo, W and X = S, Se) particularly are of much interest from a fundamental point of view but they also provide an excellent platform for ultrathin optoelectronic and photonic devices.
The PhD project is in the general field of computational materials design for energy applications. The project will be carried out under the supervision of Dr. Süleyman Er, and will involve intensive collaborations with researchers from the USA (Harvard) and the Netherlands (Center for Computational Energy Research).
The discovery of new energy materials is becoming a large-scale challenge that is far beyond the reach of experimentation but also stretching the limits of conventional computation. At DIFFER; we are working on to improve the speed and the prediction power of computation for the discovery of new solar energy conversion and energy storage materials.
In framework of the EnOp (Energie Opslag) Programme financed by Interreg (Vlaanderen–Nederland) the Solar Fuels group Plasma Solar Fuels Devices has a vacancy for a postdoctoral researcher.
Encapsulation foils are highly demanded in the production of flexible devices such as thin film transistors (TFT), organic LEDs, solar cells and so on. To bring this technology to commercial manufacturing phase, the thin film performance should be further improved and the throughput should be increased. Atmospheric-pressure PECVD is regarded as a promising tool to achieve these industrial targets because of its capability of the roll-to-roll processing and precise control over the thin film properties.
The future demands for renewable energy, electric vehicles, portable electronics and other high-power/high energy density applications require energy storage devices. Electrochemical storage has a high potential to meet the criteria, but it requires improvements in the field of high-performance electrode materials. Among the potential electrochemical materials, carbon has several advantages such as relative low cost, good electrical conductivity, benign environmental impact, high availability, and easy to process.
For the integrity of bridges, ships, spacecrafts, but also fusion reactor walls, the quality of welding is of mayor importance. The main objective of this project is to investigate the correlation between the welding plasma properties and material modification at high power fluxes such as grain and blister formation as well as embrittlement.
Our future energy infrastructure will need ways of efficiently converting, transporting and storing electricity from sustainable but fluctuating sources. One approach uses sustainable electricity for the reverse combustion of atmospheric CO2 into so-called solar fuels, thereby converting electricity into the chemical bonds of high-density fuels. DIFFER pursues plasma-assisted conversion of CO2 into CO and O2 as an exciting new approach to recycling carbon dioxide into fuels, thereby closing the carbon cycle and eliminating the need for fossil fuels.
Photo-electrochemical (PEC) solar fuel conversion is one of the most promising techniques to convert solar energy directly into its most versatile form of energy, a fuel. However, the efficiency is still low and degradation too high. We have several open BSc/MSc/internship projects for both experiments and modeling & simulation.
