Discovery of Energy‐Localized Trap States via Opto‐Electrical Spectroscopy in UWBG Perovskite La:SrSnO 3 FETs

ABSTRACT Strontium stannate perovskite (SrSnO 3 ) is emerging as a promising material for next‐generation ultra‐wide bandgap (UWBG) semiconductors due to its high electron mobility and optical transparency. However, despite the critical importance of defect analysis to utilize La...

Low-Energy Organic Ferroelectric Synaptic Transistors Enabled by Interfacially Engineered Gate Insulators

Abstract Solution-processed organic ferroelectric transistors are promising synaptic components for portable and wearable neuromorphic systems. However, compared with oxide-based platforms, these transistors generally require relatively thick ferroelectric gate layers and, conseq...

A data-driven modeling of public acceptance for fusion energy: analyzing public perceptions through future-centric empirical segmenting framework

Abstract As fusion energy approaches commercial viability, establishing strong public acceptance has become as critical as achieving technical success. This study develops a data-driven framework to analyze public perception of fusion technology, complementing traditional surveys...

Automated Geometric Correction of OpenStreetMap Buildings via Context- and Boundary-Aware Segmentation

Abstract. OpenStreetMap (OSM) is a representative open geospatial platform that provides free access to major spatial objects, including buildings worldwide, constructed through crowdsourcing-based manual digitization. However, subjective differences among contributors and the ab...
