Mapping electrical properties of large-area graphene

Marko Spasenovic

Electrical properties of graphene, such as conductivity, can vary across a wafer, which can impede the industrial acceptance of the material. Spatial inhomogeneity of conductivity results in devices from the same batch having different performance, which is incompatible with large scale manufacturing. It is hence important to have tools to map electrical properties with sufficient resolution...

Novel and cost-effective drilling technologies for geothermal systems

Geothermal is currently the most underutilized of renewable resources, even though it is in principle, via engineered geothermal systems (also called enhanced geothermal systems, EGS), possible to exploit anywhere. A key issue with deep geothermal exploitation is its high cost, with 53% of the price of exploitation expended on drilling. This is especially true for deep EGS in hard rock (HDR – Hot...

Graphene humidity sensors made with a CMOS-compatible process

Researchers at the University of Exeter have used CMOS-compatible processes to create graphene-based humidity sensors with performance on par with commercial ones. The process was demonstrated on an array of sensors produced on a 4” silicon wafer as well as on transparent and flexible PET. The work paves the way to practical use of 2D materials in low-cost, low-power, wearable and flexible...

Graphene display project to propel applications

Display components consume the most power in electronic devices such as smartphones. Portable devices usually convert electricity into light to show images and videos, which spends much energy. Alternatively, reflective-type displays in e-book readers consume little power but cannot provide colourful images nor fast frame rates to reproduce videos. Standard technologies cannot meet the...

Graphene Flagship Annual Report 2018 highlights motion to commercialization

The Graphene Flagship Annual Report 2018 is now available for download. Increasing technology readiness levels (TRL), and material quality and consistency remain the key pillars of advancing towards commercialization. As stated by the Flagship Director himself, reproducibility and manufacturability are becoming increasingly important as the technology matures and shifts from labs to the society.
