Principles and Early Historical Development of Silicon Avalanche and Geiger-Mode Photodiodes [PDF]

, 2017
The historical development of technology can inform future innovation, and while theses and review articles attempt to set technologies and methods in context, few can discuss the historical background of a scientific paradigm.

Compositional Tuning of Barium Titanium Trisulphide‐Based Perovskite Chalcogenides: Manganese and Selenium Substitution Effects on Electronic and Transport Properties

ChemistryOpen, Volume 15, Issue 5, May 2026.
We investigated the effect of manganese and selenium substitution on BaTiS3 using density functional theory calculations performed with Quantum Espresso. Elemental tuning narrows the band gap from 0.71 to 0.312 eV, slightly modifies stability and conductivity, and preserves p‐type behavior, highlighting the potential of controlled doping for energy ...

From Computational Indeterminacy to the Causal Relevance of Mental Content

Philosophy and Phenomenological Research, Volume 112, Issue 3, Page 652-663, May 2026.
ABSTRACT A central claim in contemporary cognitive science is that the neural mechanisms that bring about cognitive capacities and behavior are computations. It is also widely assumed that computations are not sensitive to the content, or the semantic properties of representations.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Toward Reliable Metal Halide Perovskite FETs: From Electronic Structure and Device Physics to Stability and Performance Engineering

Advanced Electronic Materials, Volume 12, Issue 7, 6 April 2026.
Metal halide perovskite field‐effect transistors (PeFETs) offer great promise for flexible, low‐cost, and high‐performance due to their excellent charge carrier properties. However, challenges like ion migration, hysteresis, and instability limit their performance.

Direct Write, Read, and Erase of a Vertical Heterostructure of Graphene–Monolayer Electrolyte–h‐BN Using Electric Force Microscopy

Small, Volume 22, Issue 20, 7 April 2026.
This work demonstrates bistable graphene doping of about 5 × 1012 cm−2$\rm{c{m}^{-2}}$ using a molecularly thin electrolyte confined between two, 2D crystals. The electrolyte's bistability enables multiple non‐volatile states with a conductive AFM tip writing, erasing, and sensing these states.
