Design strategies toward plasmon-enhanced 2D material photodetectors

Traditional semiconductors such as Si, GaAs, and HgCdTe seem unable to meet the development trend of electronic devices that feature ultra-small volume, lightweight, and low power consumption. These limitations of traditional ...

More efficient molecular motor widens potential applications

Light-driven molecular motors were first developed nearly 25 years ago at the University of Groningen, the Netherlands. This resulted in a shared Nobel Prize for Chemistry for Professor Ben Feringa in 2016. However, making ...

A novel universal light-based technique to control valley polarization in bulk materials

Electrons inside solid materials can only take certain values of energy. The allowed energy ranges are called "bands," and the space between them, the forbidden energies, is known as "band gaps." Both of them together constitute ...

Lead-vacancy centers in diamond as building blocks for large-scale quantum networks

Much like how electric circuits use components to control electronic signals, quantum networks rely on special components and nodes to transfer quantum information between different points, forming the foundation for building ...

Making light 'feel' a magnetic field like an electron would

Unlike electrons, particles of light are uncharged, so they do not respond to magnetic fields. Despite this, researchers have now experimentally made light effectively "feel" a magnetic field within a complicated structure ...

Light stands still in a deformed crystal

AMOLF researchers, in collaboration with Delft University of Technology, have succeeded in bringing light waves to a halt by deforming the two-dimensional photonic crystal that contains them. The researchers show that even ...

Study shines light on properties and promise of hexagonal boron nitride, used in electronic and photonics technologies

Single-photon emitters (SPEs) are akin to microscopic lightbulbs that emit only one photon (a quantum of light) at a time. These tiny structures hold immense importance for the development of quantum technology, particularly ...

Attosecond imaging made possible by short and powerful laser pulses

Extremely short pulses of laser light with a peak power of 6 terawatts (6 trillion watts)—roughly equivalent to the power produced by 6,000 nuclear power plants—have been realized by two RIKEN physicists. This achievement ...
