Advanced Functional Materials, EarlyView.This study presents a new hole transporting material (HTM) mechanism for self‐assembled monolayers in near‐infrared organic photodetectors. The formation of zwitterions induces a strong electric field that significantly increases the work function of HTM‐coated indium tin oxide substrates. The devices exhibit low dark current and noise, along with high

Mathematical models and simulations of phase noise in phase-locked loops [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2007 Phase noises in Phase-Locked Loops (PLLs) are a key parameter for communication systems that contribute the bit-rate-error of communication systems and cause synchronization problems.

The condition monitoring of the passive harmonic filters in rail way DC sub stations [PDF]
, 2013 The condition monitoring of the passive 12th and 24th harmonic filters in the DC sub station employing 12 pulse passive rectification plays the vital role of suppressing generated harmonics. The railway service of South Africa (Transnet) is confronted by

Trap‐Assisted Transport and Neuromorphic Plasticity in Lead‐Free 2D Perovskites PEA2SnI4
Advanced Functional Materials, EarlyView.An artificial retina built from lead‐free layered perovskite (PEA)2SnI4 converts light input into a persistent photocurrent and sums successive flashes over time. Micro/nanocrystals integrated on electrodes act as synapse‐like pixels that perform temporal integration directly in hardware. This in‐sensor preprocessing merges detection and computation on

Revisiting the role of the Thermally-Pulsating Asymptotic Giant Branch phase in high-redshift galaxies [PDF]
, 2015 We study the debated contribution from thermally pulsing asymptotic giant branch (TP-AGB) stars in evolutionary population synthesis models. We investigate the Spectral Energy Distributions (SEDs) of a sample of 51 spectroscopically confirmed, high-z ($1.

Imaging of Biphoton States: Fundamentals and Applications
Advanced Functional Materials, EarlyView.Quantum states of two photons exhibit a rich polarization and spatial structure, which provides a fundamental resource of strongly correlated and entangled states. This review analyzes the physics of these intriguing properties and explores the various techniques and technologies available to measure them, including the state of the art of their ...
