  • A fast light detector made of two-dimensional materials

    Two research groups at ETH Zurich have joined forces to develop a novel light detector. It consists of two-​dimensional layers of different materials that are coupled to a silicon optical waveguide. In the future, this approach can also be used to make LEDs and optical modulators. Fast and highly ef more

  • Graphene mapping 50 times faster

    Graphene is always raising high expectations, as a strong, ultrathin, two-dimensional material that could also be the basis for new components in information technology. There is huge need for characterization of graphene devices. This can be done using Raman spectroscopy. Laser light is sent to the more

  • 2D materials: arrangement of atoms measured in silicene

    Silicene consists of a single layer of silicon atoms. In contrast to the ultra-flat material graphene, which is made of carbon, silicene shows surface irregularities that influence its electronic properties. Now, physicists from the University of Basel have been able to precisely determine this corr more

What is graphene?

What is graphene? Graphene is the world's first 2D material which was initially isolated in 2004. It was discovered after scientists at The University of Manchester separated one atomic layer of graphite using simple sticky tape. This short animation takes a look at how graphene was isolated and ... more

2-D layered devices can self-assemble with precision

  • Chemical sensing with 2D materials

    During the last decade, two-dimensional materials (2DMs) have attracted great attention due to their unique chemical and physical properties, which make them appealing platforms for diverse applications in opto-electronic devices, energy generation and storage, and sensing. Among their various extra more

  • Periodic and nonperiodic chiral self-assembled networks from 1,3,5-benzenetricarboxylic acid on Ag(111)

    Surface-catalyzed reactions provide a versatile route to synthesizing new 2D materials. Here, we show that the statistical nature of an activated reaction can lead to a diversity of intermolecular bonding motifs through partially-reacted molecules. With increasing annealing, we observe different per more

  • Preparation of 2D material dispersions and their applications

    Extensive research on two-dimensional (2D) materials has triggered the renaissance of an old topic, that is, the intercalation and exfoliation of layer materials. Such top-down exfoliation produced 2D materials and their dispersions have several advantages including low cost, scalable production cap more
