Versarien receives Graphene Council's seal of approval as part of its "Verified Graphene Producer" program

Versarien has announced that it is the first graphene company in the world to successfully complete the Graphene Council's "Verified Graphene Producer" program.

The US-based Graphene Council's Program is an independent, third party verification system that involves a physical inspection of the production facilities, a review of the entire production process, a random sampling of product material and rigorous characterization and testing by a leading, international materials laboratory. The Program is based on the most recent developments in globally recognized graphene standards, surveys of graphene producers, researchers and users, as well as analysis of commercially available graphene products.

Delaware team creates graphene-silicon devices for photonics applications

Researchers at the University of Delaware have invented a technology that is meant to improve the communication between photonics devices. This new innovation could benefit smartphones, laptops, and various other consumer electronics.

silicon-graphene devices capable of transmitting radio-frequency waves at less than a picosecond at a sub-terahertz bandwidth have been successfully created. Silicon has long been a popular material for use in semiconductors found in many electronic devices. Unfortunately, there is a limit to what silicon can do in a semiconductor, due to its carrier mobility. This means that the speed a charge moves through the material, and its indirect bandgap, can dramatically limit the material’s ability to absorb and release light. But scientists believe they’ve found a solution to this problem, in the form of graphene.

First Graphene completes placement to raise USD$2.5 Million

First Graphene logo imageFirst Graphene has announced the completion of a placement to raise $3.5 million AUD (around $2.5 Million USD).

The raised funds will be used for general working capital purposes and to advance the Company’s facility at the Graphene Engineering Innovation Centre at the University of Manchester. Additionally, an increasing effort will be made to expand the sales and marketing functions of the Company.

ISO publishes standard on matrix of properties and measurement techniques for graphene

The International Organization for Standardization (ISO) has published standard ISO/TR 19733:2019, “Nanotechnologies — Matrix of properties and measurement techniques for graphene and related two-dimensional (2D) materials”.

ISO states that since graphene was discovered in 2004, it has become one of the most attractive materials in application research and device industry due to its supreme material properties and it is expected that applications of graphene could replace many of the current device development technology in flexible touch panel, organic light emitting diode (OLED), solar cell, supercapacitor, and electromagnetic shielding.

International team explores graphene-substrate interactions related to surface charges

Due to graphene's 2D geometry, most of the device applications require graphene to be partially or fully supported by a substrate, which is typically silicon dioxide (SiO2). An important example of a typical graphene structure on SiO2 is the graphene field effect transistor – GFET, a sheet of graphene connected to metal terminals on the planar substrate. The current common understanding is that graphene interacts with SiO2 through weak, long-range van der Waals forces, even though experimental evidence suggests a surprisingly strong interaction between graphene and SiO2 that affects all properties of the device.

International team explores graphene-substrate interactions related to surface charges image

Now, a multinational research team from the University of Trento, Italian Space Agency and Fondazione Bruno Kessler in Italy, Graphenea in Spain, Institute of Chemical Engineering Sciences and University of Patras in Greece, and Queen Mary University of London in the UK has shown that surface charges on the oxide are a main factor of strong interaction between graphene and SiO2, paving the way for designing 2D material interaction with a substrate through manipulation of surface charges. Such control of graphene-substrate interactions would facilitate the development of new graphene-based microelectronic devices.
