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...
