Thin 2D Materials Pack a Heavy Punch

Two-dimensional materials are thin — only a few atomic layers thick. But their potential to change IR imaging, quantum information technology and more is huge.

HANK HOGAN, CONTRIBUTING EDITOR, [email protected]

Two-dimensional materials such as graphene, as well as composite materials such as the layered semiconductor germanium selenium, could have a big impact on myriad applications. Composite materials that act as a single-photon emitter may be valuable in quantum information technology, where being able to produce a single photon on demand enables new applications. As for graphene, it has optical properties that potentially may make it useful in commercially important areas such as the IR transceivers used for data communication. Researchers at Imec investigate the integration of...Read full article

    van der waals
    Van der Waals forces refer to the attractive or repulsive forces between molecules (or parts of molecules) that arise from fluctuations in electron distribution. These forces are relatively weak compared to covalent or ionic bonds but play a crucial role in determining the physical and chemical properties of substances, particularly in the context of intermolecular interactions. Types of and key points about Van der Waals Forces: London dispersion forces: Also known as dispersion forces or...
    quantum dots
    A quantum dot is a nanoscale semiconductor structure, typically composed of materials like cadmium selenide or indium arsenide, that exhibits unique quantum mechanical properties. These properties arise from the confinement of electrons within the dot, leading to discrete energy levels, or "quantization" of energy, similar to the behavior of individual atoms or molecules. Quantum dots have a size on the order of a few nanometers and can emit or absorb photons (light) with precise wavelengths,...
