Enhanced THz Emission and Exciton Transfer in Monolayer MoS2/GaAs Heterostructures
This study demonstrates enhanced terahertz (THz) emission from a hybrid structure combining monolayer MoS2 with low‐temperature‐grown GaAs. The mixed‐dimensional van der Waals heterostructure shows a 15% increase in THz output and improved optical conductivity, driven by efficient exciton transfer and nonlinear optical effects, offering a new route for

Transverse‐Electric Cherenkov Radiation for TeV‐Scale Particle Detection
Finite refractive indices of naturally existing materials place a fundamental ceiling on the momentum of detectable particles in traditional Cherenkov detectors. This work demonstrates transverse‐electric graphene plasmon Cherenkov radiation, breaking the momentum barrier for particle detection beyond the TeV scale with exceptional robustness and ...

Improved Electron Transport Properties in InSb/Ga0.22In0.78Sb Composite Channel HEMT Structures
The effectiveness of double‐sided Te δ‐doping and engineered buffer structure consisting of GaSb buffer and AlInSb‐graded buffer is investigated in InSb/Ga0.22In0.78 Sb composite channel HEMTs. The degree of threading dislocation suppression is quantitatively analyzed using a pair‐annihilation model.

Defect characterization plays a crucial role in semiconductor research, yet the development of fast, cheap, and nondestructive tools remains challenging. This work applies electron channeling contrast imaging (ECCI) to III–V thin films on silicon, examining beam parameters and diffraction conditions.

Toward thin GaSb Buffer Layers Grown on On‐Axis (001) Silicon by Molecular Beam Epitaxy
The monolithic integration of III‐Vs on Silicon (Si) is of great interest for the development of active photonic integrated circuits (PICs). The main challenge is to achieve a high‐quality epitaxy of the III‐V on the Si substrate, as the differences ...

Mid‐Infrared Free‐Space Optical Communications: Technologies, Demonstrations and Future Directions
Free‐space optical (FSO) communication is increasingly extending beyond the near‐infrared to the mid‐wave infrared (MWIR) and long‐wave infrared (LWIR) regions, which offer reduced turbulence, scattering and absorption for more robust links. This review summarises recent advances in MWIR/LWIR FSO technologies, including quantum cascade lasers, lithium ...
