Polarization and Dielectric Study of Methylammonium Lead Iodide Thin Film to Reveal its Nonferroelectric Nature under Solar Cell Operating Conditions

Md Nadim Ferdous Hoque, Mengjin Yang, Zhen Li et al. · 2016 · ACS Energy Letters

Researchers have debated whether methylammonium lead iodide (MAPbI 3 ), with a perovskite crystal structure, is ferroelectric and therefore contributes to the current–voltage hysteresis commonly observed in hybrid perovskite solar cells…

A Markov-Middleton Model for Bursty Impulsive Noise: Modeling and Receiver Design

Gaëtan Ndo, Fabrice Labeau, Marthe Kassouf · 2013 · IEEE Transactions on Power Delivery

Transmission over channels impaired by impulsive noise, such as in power substations, calls for peculiar mitigation techniques at the receiver side in order to cope with signal deterioration. For these techniques to be effective, a…

A microfluidic transistor for automatic control of liquids

Kaustav A. Gopinathan, Avanish Mishra, Baris R. Mutlu et al. · 2023 · Nature

Abstract Microfluidics have enabled notable advances in molecular biology 1,2 , synthetic chemistry 3,4 , diagnostics 5,6 and tissue engineering 7 . However, there has long been a critical need in the field to manipulate fluids and suspended matter with the precision, modularity and scalability of electronic circuits 8–10 . Just as the electronic transistor enabled unprecedented advances in the automatic control of electricity on an electronic chip, a microfluidic analogue to the transistor could enable improvements in the automatic control of reagents, droplets and single cells on a microflui

Timing-Error Optimized Architecture for Current-Steering DACs

Ramin Babaee, Shahab Oveis Gharan, Martin Bouchard · 2025 · arXiv

We propose a novel digital-to-analog converter (DAC) weighting architecture that statistically minimizes the distortion caused by random timing mismatches among current sources. To decode the DAC input codewords into corresponding DAC switches, we present three algorithms with varying computational complexities. We perform high-level Matlab simulations to illustrate the dynamic performance improvement over the segmented structure.
