Advanced Materials, EarlyView.We report perovskite photodetectors with record specific detectivities exceeding 1013 Jones with a novel molecular design strategy to functionalize self‐assembled monolayers (SAMs) with ferrocene (Fc) derivatives. Fc‐SAM‐based devices also exhibit strong operational stability and enable data transmission rates exceeding 1 Mbps in a LiFi system ...

Helicity‐Defined Analog Conductance States in Chiral Perovskite Synapses
Advanced Materials, EarlyView.Chiral perovskite synapses convert the handedness of circularly polarized light into persistent analog memory during electrical programming. An optimized n = 3 structure combines strong helicity selectivity with low read noise, enabling 72 distinct conductance levels.

GNSS Signal Design Approach Considering Receiver Performance [PDF]
, 2008 In this work we establish a systematic approach to design optimum chip pulse shapes for DS-CDMA systems which are absolutely band-limited, whose energy is mainly concentrated in one chip duration, and that minimize the Cramer-Rao lower bound for the ...

Stochastic digital filtering of nuclear radiation signals : a new approach
, 1996 We present a new approach for the design of optimum filters with good low frequency rejection suitable for high resolution nuclear spectrometry. The method, based on digital filtering techniques, permits to well approximate the theoretical signal-to ...

Thickness‐Defined Transport Regime Toward Near‐Ideal Area‐Type Switching
Advanced Materials, EarlyView.By thinning the oxide layer, memristors pass from diode‐like and battery‐effect‐dominated behavior toward eventual short‐circuit failure. Within the intermediate 5–6 nm window, they reach a near‐ideal analog area‐type switching regime, featuring symmetric hysteresis, area‐dependent conductance, and continuous linear programming of HRS and LRS with ...

Biomass DNA: An Emerging Building Block for Advanced Materials
Advanced Materials, EarlyView.Biomass DNA is rapidly emerging from its traditional role as a genetic blueprint to serve as a versatile abundant, highly programmable polymeric building block. This review highlights the transformation of macroscopic bulk biomass DNA into next generation of functional materials, spanning from dynamic hydrogels, sustainable bioplastics, and high ...

Ferroionic‐Assisted, Charge‐Driven Polymorphic Phase Engineering for Multilevel Memristive Devices
Advanced Materials, EarlyView.A CuInP2S6/Mo0.92W0.08Te2 heterostructure enables a gradual semiconductor‐to‐semimetal phase transition through Cu+ ion migration and charge accumulation. The spatially engineered 2H/1T′ mixed phases produce continuously tunable conductance states in a two‐terminal geometry, while suppressing depolarizing fields and stabilizing the metastable 1T′ phase.
