Micromegas operation in high pressure xenon: charge and scintillation readout

, 2010
The operational characteristics of a Micromegas operating in pure xenon at the pressure range of 1 to 10 bar are investigated. The maximum charge gain achieved in each pressure is approximately constant, around 4x10^2, for xenon pressures up to 5 bar and

Dilution Effect for High‐Performance Multiple‐Component Near‐Infrared Organic Photodetectors

Advanced Science, EarlyView.
The dilution effect in multi‐component organic photodetector effectively suppresses non‐radiative decay and minimizes dark current, while energy‐level‐offset‐governed electron transfer between acceptors maintains efficient charge transport. This synergistic mechanism collectively enables remarkable device performance, including high detectivity and ...

A Review of Transient Characterization Techniques for Quantum Dot Light‐Emitting Diodes

Advanced Physics Research, EarlyView.
This review surveys transient characterization techniques for quantum dot light‐emitting diodes, including TRPL, TREL, TA, and E‐TA. These methods resolve carrier‐selective dynamics across multiple time scales, enabling direct analysis of charge injection, exciton formation and recombination, efficiency roll‐off, and device degradation.

Predicting solar cell efficiencies using historical data from a manufacturing process

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The solar cell manufacturing data of a passivated emitter and rear cell solar cell manufacturing plant was studied to assess the effects of tool usage and the processing time spent on each tool on the solar cell efficiency. Since manufacturing processes involve several steps with multiple tools, tracing their quality parameters back to the ...
