Efficient, 'Green' Quantum-Dot Solar Cells Exploit Defects

Scanning electron microscope image of electrodes infiltrated with quantum dots (left) and the corresponding distributions of Cu, In, Zn and Se across the film thickness.

Novel quantum dot solar cells developed at Los Alamos National Laboratory match the efficiency of existing quantum-dot based devices, but without lead or other toxic elements that most solar cells of this type rely on. "This quantum-dot approach shows great promise for a new type of toxic-element-free, inexpensi

Broadband Enhancement Relies on Precise Tilt

Broadband enhancement of the on-chip single photon extraction via tilted hyperbolic metamaterials. A quantum emitter is positioned very close to a hyperbolic metamaterial, whose optical axis is tilted with respect to the end facet of nanofiber.

Quantum photonics involves a new type of technology that relies on photons, the elementary particle of light. These photons can potentially carry quantum bits of information over large distances. If the photon source could be placed on a single chip and made to produce photons at a high rate, this could enable hi

Twisting 2D Materials Uncovers Their Superpowers

The twist angle between the layers governs the crystal symmetry and can lead to a variety of interesting physical behaviours, such as unconventional superconductivity, tunnelling conductance, nonlinear optics and structural super-lubricity.

Two-dimensional (2D) materials, which consist of a single layer of atoms, have attracted a lot of attention since the isolation of graphene in 2004. They have unique electrical, optical, and mechanical properties, like high conductivity, flexibility and strength, which makes them promising materials for such th
