Linking Device Performance to Nanoscale Photoactivation of Grain Boundaries in 2D Hybrid Halide Perovskites

Advanced Materials Technologies, Volume 11, Issue 15, 7 August 2026.
The opto‐electronic response of polycrystalline (PEA)2PbBr4 thin films is investigated by correlating macroscopic photodetector performance with nanoscale mapping techniques. Grain boundary density is systematically tuned through crystallization control and linked to device responsivity.

Long‐Wavelength Infrared InAs/GaSb T2SLs on Silicon: A Review

Advanced Photonics Research, Volume 7, Issue 8, August 2026.
This review summarises growth techniques for GaSb/GaAs/Si wafers, compares different growth techniques for GaSb buffer on GaAs wafers, LWIR InAs/GaSb T2SLs on InAs, GaSb, and GaAs wafers and proposes the buffer design for the growth of LWIR InAs/GaSb T2SLs on Si wafers, shown in the schematic.

Carrier Funneling and Luminescent Collimation for Extreme Diffuse Light Concentration

Advanced Photonics Research, Volume 7, Issue 8, August 2026.
Luminescent concentrators show performance millions of times below their thermodynamic limit because of their inefficient design. Carrier funneling combined with luminescent collimation decouples concentration from propagation distance, breaking the practical limitation of current approaches.

Compact Fourier‐Transform Spectrometer on Thin‐Film Lithium Niobate via Mode‐Circulating Modulation

Advanced Photonics Research, Volume 7, Issue 8, August 2026.
Schematic diagram of the proposed compact on‐chip Fourier‐transform spectrometer on thin‐film lithium niobate that exploits mode‐circulating electro‐optic modulation, in which guided light is sequentially converted among multiple spatial modes to accumulate multiple phase modulation events within a single physical modulation arm.

Giant Exfoliation Induced Magnetic Coercivity in Fe3GaTe2

Advanced Electronic Materials, Volume 12, Issue 15, 10 August 2026.
Mechanical exfoliation is shown to transform the van der Waals ferromagnet Fe3GaTe2 from a soft into a hard magnetic system. Reducing thickness drives a crossover to single‐domain behavior, dramatically enhancing in‐plane coercivity to near–permanent‐magnet levels at room temperature.

Ni–Cr Substitution in TiFe: An Integrated Experimental–Modeling Study of Phase Stability and Hydride Thermodynamics

Advanced Energy and Sustainability Research, Volume 7, Issue 8, August 2026.
Combined experimental and theoretical approaches reveal how Cr and Ni substitution in TiFe‐based alloys tune lattice expansion and hydride thermodynamics. While both elements increase hydride stability, they exert opposite effects on the entropy of hydrogen desorption, providing new insight into thermodynamic design of AB‐type hydrogen storage ...
