Graphene on TEM grids enables extreme resolution imaging

Transmission electron microscopy (TEM) is a microscopy method in which an electron beam images a specimen by transmission. The specimen is usually an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as...

Graphene mechanical pixels for Interferometric Modulator Displays

A graphene interferometric modulator display (GIMOD) was created by teams from SCALE Nanotech (Estonia), Kavli Institute of Nanoscience (the Netherlands) and Graphenea (Spain). Interferometric displays (IMODs) are a technology on the rise for displays that have low power consumption and high performance in bright environments, properties that are well-aligned with...

Graphene (GFET) Chemical Sensors

From toxic leaks in industrial facilities to administering drugs in medical clinics, there is always a real need to quickly and effectively detect chemicals which are normally invisible to the naked eye. Huge strides in chemical sensing technology over recent years have enabled more efficient detection of lower concentrations of...

Graphene for spintronics – electron spin g factor insensitive to external effects

Researchers have probed the electron spin g factor in graphene and discovered that, surprisingly, this factor is insensitive to external effects such as charge carrier type, density and mobility. The g factor is an important parameter that defines spin properties of electrons in a material, with fundamental implications in spintronic...

Graphenea provides material for space experiment

Graphenea’s suspended CVD graphene will be used in weightless conditions for testing the possibility of designing a light sail. Light sails are propulsion systems that utilize the pressure of light to move an object through space. Graphenea speaks to Santiago Cartamil-Bueno, leader of GrapheneX, the team of PhD students that...
