Watching a Quantum Material Lose Its Stripes

lsno-fig1-illustration-960px.jpg

In quantum materials, periodic stripe patterns can be formed by electrons coupled with lattice distortions. To capture the extremely fast dynamics of how such atomic-scale stripes melt and form, Berkeley Lab scientists used femtosecond-scale laser pulses at terahertz frequencies. Along the way, they found some unexpected behavior.

Quantum Emitting Answer Might Lie in the Solution

APL003747-Waks-colloidalperovskite.jpg

Lead trihalide perovskite nanocrystals are promising candidates as light sources. Coupling quantum emitters with nanophotonic cavities can significantly boost efficiency, but this approach has not been explored with these nanocrystals. Now, researchers have demonstrated a simple approach for coupling solution-synthesized cesium lead tribromide perovskite nanocrystals to silicon nitride photonic cavities. The resulting room temperature light emission is enhanced by an order of magnitude above what perovskites can emit alone. They report their results this week in Applied Physics Letters.
