TL;DR: The fully integrated functionality and small size of Neuropixels probes allowed large populations of neurons from several brain structures to be recorded in freely moving animals and opens a path towards recording of brain-wide neural activity during behaviour.

TL;DR: A suite of electrophysiological tools comprising a miniaturized high-density probe, recoverable chronic implant fixtures, and algorithms for automatic post hoc motion correction are demonstrated, enabling an order-of-magnitude increase in the number of sites that can be recorded in small animals, such as mice, and the ability to record from them stably over long time scales.
Journal ArticleDOI
40% efficient thin-film surface-textured light-emitting diodes by optimization of natural lithography
Reiner Windisch,B. Dutta,Maarten Kuijk,A. Knobloch,S Meinlschmidt,S. Schoberth,Peter Kiesel,Gustaaf Borghs,G. H. Döhler,Paul Heremans +9 more
TL;DR: In this article, a monolayer of randomly positioned polystyrene spheres acts as a mask for dry etching of a GaAs/AlGaAs LED with a textured top surface and a rear reflector.
Journal ArticleDOI
Light-emitting diodes with 31% external quantum efficiency by outcoupling of lateral waveguide modes
TL;DR: In this article, a combination of light scattering at a textured top surface and reflection on a backside mirror was proposed to achieve 22% external quantum efficiency of nonresonant cavity (NRC) light-emitting diodes.
Journal ArticleDOI
Light-extraction mechanisms in high-efficiency surface-textured light-emitting diodes
TL;DR: In this paper, a detailed quantitative analysis of the light extraction and loss mechanisms in high-efficiency GaAs-AlGaAs surface-textured thin-film light-emitting diodes (LEDs) is presented based on a Monte Carlo simulation.
