Field Emission Control via Work Function Modulation in Semimetallic Graphene Edge Cathodes

open access: yesSmall, Volume 22, Issue 10, 17 February 2026.
Graphene edge cathodes, with atomically sharp edges, high carrier mobility, and electrostatically tunable electronic structure, enable a nanoscale vacuum transistor whose off‐channel gate directly modulates the emitter work function. The device achieves gate‐tunable current saturation from 10 to 300 K, low leakage, and amplification behavior enabled by

Electrical spin injection and detection in an InAs quantum well

open access: yes, 2006
We demonstrate fully electrical detection of spin injection in InAs quantum wells. A spin polarized current is injected from a NiFe thin film to a two-dimensional electron gas (2DEG) made of InAs based epitaxial multi-layers.

Polarity‐Controlled Volatile HfO2 Memristors with Bimodal Conductance for Neuromorphic Synapses and Reservoir Computing

open access: yesAdvanced Science, Volume 13, Issue 3, 14 January 2026.
This study demonstrates a TiN/HfO2/ITO memristor exhibiting field‐induced bimodal volatile switching behavior originating from ion bombardment during sputtering. The dipole‐driven, polarity‐dependent states produce multilevel output responses that expand the reservoir's output dimensionality and enhance encoding diversity.

Study of tri-gate AlGaN/GaN MOS-HEMTs for power application

open access: yesMicro and Nano Engineering, 2020
In this letter, we present high-performance AlGaN/GaN high electron mobility transistor (HEMT) by 3-dimensional (3D) tri-gate. Due to the excellent channel control of tri-gate structure, the tri-gate HEMT shows the low subthreshold swing (SS) of 65 mV ...

The validated French CFAbd‐Score reveals a lower burden of gastrointestinal symptoms in patients on Elexacaftor/Tezacaftor/Ivacaftor

open access: yesJournal of Pediatric Gastroenterology and Nutrition, Volume 82, Issue 1, Page 24-32, January 2026.
Abstract Objectives Multiorgan abdominal involvement is a hallmark of Cystic fibrosis (CF). The CFAbd‐Score© is the first CF‐specific gastrointestinal patient reported outcome‐measure (PROM) developed following FDA‐guidelines. The PROM has proved to sensitively differentiate people with CF (pwCF) from healthy controls (HC).
