A new experimental pilot line will integrate graphene and related layered materials (GRMs) in semiconductor platforms

​The European Commission recently invited a group of Graphene Flagship partners and associated members to set up an experimental pilot line to integrate graphene and related layered materials (GRMs) in semiconductor platforms.

The project aims to establish a European ecosystem covering the entire value chain, from tool manufacturers and chemical and material providers to pilot lines. This collaborative project will pioneer the manufacture of new prototype electronics, photonics and sensors integrating GRMs. The 2D Experimental Pilot Line (2D-EPL) will offer prototyping services to companies, research centers and academics to develop their innovative technologies based on 2D materials in an established processing platform.

Researchers develop a graphene metamaterial film that absorbs sunlight with minimal heat loss

Researchers from Swinburne University developed a graphene-based highly efficient solar absorbing film that absorbs sunlight with minimal heat loss. The film rapidly heats up in an open environment and has great potential in solar thermal energy harvesting systems - in addition to other applications such as thermophotovoltaics (directly converting heat to electricity), solar seawater desalination, light emitters and photodetectors.

New graphene-based metasurface capable of independent amplitude and phase control of light

A KAIST research team in collaboration with the University of Wisconsin-Madison theoretically developed a graphene-based active metasurface capable of independent amplitude and phase control of mid-infrared light. This research gives a new insight into modulating the mid-infrared wavefront with high resolution by solving the problem of the independent control of light amplitude and phase, which has remained a long-standing challenge.

Light modulation technology is essential for developing future optical devices such as holography, high-resolution imaging, and optical communication systems. Liquid crystals and a microelectromechanical system (MEMS) have previously been utilized to modulate light. However, both methods suffer from significantly limited driving speeds and unit pixel sizes larger than the diffraction limit, which consequently prevent their integration into photonic systems.

Special substrates enable large single crystal bi-/tri-layer graphene growth

Researchers of the Center for Multidimensional Carbon Materials (CMCM) within the Institute for Basic Science (IBS, South Korea), in collaboration with UNIST and Sungkyunkwan University teams, have reported the fabrication and use of single crystal copper-nickel alloy foil substrates for the growth of large-area, single crystal bilayer and trilayer graphene films.

The growth of large area graphene films with a precisely controlled number of layers and stacking order can open new possibilities in electronics and photonics but remains a challenge. This study showed an example of the synthesis of bi- and trilayer graphene sheets larger than a centimeter, with layers piled up in a specific manner, namely AB- and ABA-stacking.

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.
