PbS colloidal quantum dots imagers: From single devices to arrays, flexible platforms, and CMOS‐integrated systems

open access: yesFlexMat, EarlyView.
Abstract Imagers operating in the visible to near‐infrared (NIR) range play an important role in applications such as industrial sorting, security surveillance, and autonomous driving. However, conventional imaging technologies based on silicon and III–V semiconductors suffer from several limits, including restricted spectral range, high fabrication ...

Efficient near‐infrared light‐emitting diodes via enlarging grains of tin‐based perovskites

open access: yesInfoMat, EarlyView.
In this work, penicillamine molecules are introduced into Sn‐based perovskites to slow crystallization, yielding large‐grain films with reduced grain boundaries and passivated defects. The resulting perovskite light‐emitting diodes achieve a maximum external quantum efficiency of 17.5% at 894 nm and an operational half‐lifetime of 0.95 h under current ...

View Order With Arbitrary Center Echoes

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To provide explicit, vendor‐independent view‐order constructions that enable selection of an arbitrary center echo in multi‐shot imaging, with a focus on RARE and MPRAGE. Methods Vendor‐independent view‐order methods were developed to assign echo and shot indices to a prescribed set of phase encodes, enabling explicit selection of the ...
