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.

Exactly soluble model for a fractionalized Weyl semimetal

Physical Review Research, 2019
We construct an exactly solvable lattice model of a fractional Weyl semimetal. The low-energy theory of this strongly interacting state is that of a Weyl semimetal built out of fractionally charged fermions.

Coexisting Rashba/Dresselhaus Spin Splitting in Solution‐Processed Bournonite Films Using Circular Photogalvanic Effect

Advanced Functional Materials, Volume 36, Issue 29, 9 April 2026.
Circular photogalvanic effect measurements and first‐principles calculations reveal spin‐splitting states in solution‐processed bournonite films (CuPbSbS3) due to structural and bulk inversion asymmetry. The results provide experimental confirmation of coexisting Rashba and Dresselhaus spin‐splitting states in this non‐centrosymmetric chalcogenide ...

Tip induced unconventional superconductivity on Weyl semimetal TaAs

, 2016
Weyl fermion is a massless Dirac fermion with definite chirality, which has been long pursued since 1929. Though it has not been observed as a fundamental particle in nature, Weyl fermion can be realized as low-energy excitation around Weyl point in Weyl

Magnetic-resonance-induced non-linear current response in magnetic Weyl semimetals

AAPPS Bulletin
In this work, we propose a geometric non-linear current response induced by magnetic resonance in magnetic Weyl semimetals. This phenomenon is in analog to the quantized circular photogalvanic effect (de Juan et al., Nat. Commun.

Discovery of a new type of topological Weyl fermion semimetal state in MoxW1−xTe2

Nature Communications, 2016
A Type II Weyl fermion semimetal has been predicted in MoxW1−xTe2, but it awaits experimental evidence. Here, Belopolski et al. observe a topological Fermi arc in MoxW1−xTe2, showing it originates from a Type II Weyl fermion and offering a new platform ...

The discovery of dynamic chiral anomaly in a Weyl semimetal NbAs

Nature Communications, 2020
Unique electronmagnetic response of Weyl semimetals have only been reported in static field regime. Here, the authors report evidence of a dynamical chiral anomaly response realized by internal collective lattice deformation with an external static ...

Temperature-tunable Fano resonance induced by strong coupling between Weyl fermions and phonons in TaAs

Nature Communications, 2017
The study of lattice vibrations coupled to electronic excitations may provide an avenue for exploring exotic physical phenomena. Here, Xuet al. observe a Fano resonance in the Weyl semimetal TaAs, revealing evidence for a strong coupling between phonons ...
