Quantum dots beat traditional photosensitizers at their own game. They tackle reactions once thought too tough for ...

The quantum battery (QB) has been proposed as an alternative to the electrochemical energy storage devices we know so well.

The global microgrid market is projected to hit the market valuation of US$ 191.01 billion by 2033 from nearly US$ 40.9 ...

In order to determine the spectral characteristics of the material (for example, the chemical composition at each point), we apply silver, gold or platinum to the probe in such a way that a single ...

Why it matters: 1. Quantum dots, often called artificial atoms, can mimic atomic orbitals but have not yet been used to simulate orbital hybridization, a crucial process in real atoms. 2. While ...

Abstract: We study the optical response of multilayer graphene quantum dots at THz frequencies. We fabricate 73 nm diameter graphene quantum dots in an array of ~1mm 2 size. We demonstrate optical ...

Jul 26, 2024 Graphene-quantum dot hybrid enables compact multispectral light detection (Nanowerk Spotlight) Light detection across multiple wavelengths underpins numerous technological applications, ...

Graphene vs. metallic quantum dots: the confined states. (a–c) The EPWE calculated electronic structure for (a) the smallest graphene quantum dot (GQD) and (b, c) for the same size 2D metallic quantum ...

Graphene quantum dots (GQDs) are a part of the carbon quantum dots family.1 These zero-dimensional carbon nanomaterials possess many superior properties, such as low biological toxicity, nanoscale ...

In graphene as well as in other carbon-based materials, spin-orbit coupling and hyperfine interaction are both weak: this makes graphene quantum dots especially appealing for spin qubits.

Although Velasco’s lab uses STM to create and study graphene quantum dots, a simpler system using metal electrodes in a cross-bar array could be used in a magnetic sensor device. Because graphene is ...
