Spectral-Domain Optical Coherence Tomography in Lightning-induced Maculopathy

Ophthalmic Surgery, Lasers and Imaging Retina, 2012
The authors report a case of lightning-induced chorioretinal burn accompanied by mild anterior segment injuries. Spectral-domain optical coherence tomography images were used to document the progressive retinal and choroidal changes. As evidenced by this report, despite being sight-threatening, such injuries may allow for a significant functional ...

Critical Role of Polymer Gate Dielectrics on the Charge Carrier Transport in Perovskite Field‐Effect Transistors

Advanced Functional Materials, EarlyView.
Charge transport in 2D tin perovskite FETs is shown to be governed by dielectric interface behavior. Polar polymer dielectrics induce dipolar disorder that localizes carriers, whereas nonpolar polymers suppress trapping and enable superior charge transport, ensuring stable and reliable transistor operation. ABSTRACT Understanding the role of interfaces

Toward Spectral-Domain Optical Coherence Tomography on a Chip

IEEE Journal of Selected Topics in Quantum Electronics, 2012
We present experimental results of a spectral-domain optical coherence tomography system based on an integrated optical spectrometer. A 195-channel arrayed-waveguide-grating (AWG) spectrometer with 0.4-nm channel spacing centered at 1300 nm and a 125-channel AWG with 0.16-nm channel spacing centered at 800 nm have been fabricated in silicon oxynitride ...

Cross‐Layer Molecular Design for Coherent Interface Passivation in Rigid and Flexible Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
A cross‐layer passivation strategy employing molecularly designed thiazol‐5‐ylmethanamine hydrochloride (TMACl) enables coherent defect regulation at the SnO2/perovskite interface, stabilizes both layers, promotes phase‐pure α‐FAPbI3 formation, and enhances charge extraction, delivering PCEs of 26.44% in rigid and 24.72% in flexible perovskite solar ...
