Engineering Large-Grain Metal Halide Perovskite Films via Chemical Vapor Deposition for High-Performance, Ultralow-Noise Perovskite Photodetectors. [PDF]
Adv Sci (Weinh)Chemical vapor deposition produces large‐grain, phase‐pure CsPbBr3 films (grains up to 35 µm) with Drude‐like terahertz photoconductivity and twofold higher carrier mobility versus spin‐coated references. These microstructural advances translate into photodetectors with a detectivity of 8.4 × 1012 Jones, dark current below 1 pA cm−2, X‐ray sensitivity ...

Preliminary results for the extraction and measurement of cosmogenic in situ C-14 from quartz [PDF]
, 2004 Radiocarbon is produced within minerals at the earth's surface (in situ production) by a number of spallation reactions. Its relatively short half-life of 5730 yr provides us with a unique cosmogenic nuclide tool for the measurement of rapid erosion ...
