This study fabricated and analyzed AlGaInP-based red micro–light-emitting diodes (LEDs)
ranging from 2 to 15 μm in size. To collect photons from a single micro-LED at this scale, a …

As a promising high mobility p-type wide bandgap semiconductor, copper iodide has
received increasing attention in recent years. However, the defect physics/evolution are still …

Arrays of floating neural sensors with a high channel count that covers an area of square
centimeters and larger would be transformative for neural engineering and brain–machine …

Selenium (Se) has been studied for over 140 years as the first solid-state solar cell, yet it has
only achieved a maximum power conversion efficiency of 6.5%. To improve the efficiency …

Artificial leaves could be the breakthrough technology to overcome the limitations of storage
and mobility through the synthesis of chemical fuels from sunlight, which will be an essential …

Applications of lead halide perovskites in solar cells and photo-and ionising radiation
detectors are based on effective charge carrier generation and transport. The perovskites …

We present a conceptual approach for the localisation and characterisation of local sites of
recombination in high diffusion length semiconductors under photovoltaic field conditions …

The aging dynamics of materials used to build the active part of optoelectronic devices is a
topic of current interest. We studied epitaxial samples of GaAs doped with Ge and Sn up to …

This paper questions the validity of tN A/DN t technique for solar cell optimization and
establishes the scientifically and experimentally-justified NA/DN tt parameter optimization …

Fully microscopic many-body models based on inputs from first principles density functional
theory are used to calculate the carrier losses due to radiative-and Auger-recombinations in …
