Exploring Double NDR Modulation and UV‐NIR Photodetection in MoS2/Sb2Se3 Heterostructures

open access: yesAdvanced Optical Materials, EarlyView.
In this study, a van der Waals Sb2Se3/MoS2 heterostructure exhibits dual negative differential resistance (NDR) peaks at room temperature. The first originates from band‐to‐band tunneling, while the second, triggered under laser illumination, is attributed to trap states and recombination dynamics.

Illuminating Quantum Phenomena in 2D Materials: The Power of Optical Spectroscopy

open access: yesAdvanced Optical Materials, EarlyView.
Atomically thin 2D materials host quantum tunnelling, plasmonic and excitonic phenomena driven by reduced dimensionality and strong many‐body interactions. This review links these effects to state‐of‐the‐art optical probes—NSOM, pump–probe, CARS, TRR, and optical frequency comb spectroscopy—highlighting how their ultrahigh spatial–temporal resolution ...

Origin of Ultraviolet‐Induced High‐Temperature Photovoltaic Response at Pt/Gd‐Doped CeO2 Interface

open access: yesAdvanced Optical Materials, EarlyView.
Oxygen uptake induced by UV irradiation generates an oxygen chemical potential gradient across acceptor‐doped ceria at high temperatures. Besides the photovoltage caused by band bending at the heterojunction interface, the observed voltage can also be attributed to the Nernst voltage arising from the oxygen potential gradient.

Topological Valley Photonic Waveguides: Scattering Matrix Evaluation for Linear Computing

open access: yesAdvanced Photonics Research, EarlyView.
This research is focused on the design of a 6‐port junction via valley photonic crystal waveguides to achieve equal power splitting of an incident signal towards three other ports. An in‐depth study is carried out to extract its corresponding scattering matrix.
