New superlattice material for future energy efficient devices

A team of international physicists including Jennifer Cano, Ph.D., of Stony Brook University, has created a new material layered by two structures, forming a superlattice, that at a high temperature is a super-efficient insulator ...

Simple materials offer a peek into the quantum realm

As reported in Nature Physics, a Berkeley Lab-led team of physicists and materials scientists was the first to unambiguously observe and document the unique optical phenomena that occur in certain types of synthetic materials ...

When semiconductors stick together, materials go quantum

A team of researchers led by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a simple method that could turn ordinary semiconducting materials into quantum machines—superthin ...

Sandwich structure of nanocrystals as quantum light source

Excited photo-emitters can cooperate and radiate simultaneously, a phenomenon called superfluorescence. Researchers from Empa and ETH Zurich, together with colleagues from IBM Research Zurich, have recently been able to create ...

Nanocrystals arrange to improve electronics

Lawrence Livermore National Laboratory (LLNL) researchers are working to make better electronic devices by delving into the way nanocrystals are arranged inside of them.

Putting noise to work

Noise is often undesirable—for example, in a recorded conversation in a noisy room, in astronomical observations with large background signals, or in image processing. A research team from China, Spain and Germany has demonstrated ...

Flipping the switch on supramolecular electronics

Graphene and related materials hold great potential for technological applications such as electronics, sensors, and energy storage devices, among others. Thanks to their high surface sensitivity, these materials are an ideal ...
