Structural and Compositional Effects on the Scintillation Properties of Fast Emitting Metal‐Organic Frameworks

Advanced Science, EarlyView.
The crystalline structure, the atomic numbers of the constituent elementsand the size of MOF crystals each influence their photoluminescence and scintillation properties in distinct ways. Together, these factors provide valuable guidelines for designing systems with optimized performance and tunable timing characteristics, arising from the synergistic ...

Simultaneous Multi-Target Monitoring with Terahertz Leaky-Wave Radar

Leaky-wave radar has emerged as a viable alternative to mechanically steered terahertz radar systems. This technique is enabled by the relationship between angle-of-arrival and frequency, allowing the both the range and angle information of a target to ...

HgCdTe-based heterostructures for terahertz photonics

APL Materials, 2017
Due to their specific physical properties, HgCdTe-based heterostructures are expected to play an important role in terahertz photonic systems. Here, focusing on gated devices presenting inverted band ordering, we evidence an enhancement of the terahertz ...

Defect Driven Electronic Structure Reconfiguration and Hierarchical Phonon Suppression in Ag2Se Thermoelectrics

Advanced Science, EarlyView.
Indium substitution in Ag2Se nanocrystals simultaneously tailors electronic structure and lattice dynamics. Fermi‐level upshift and band‐gap narrowing enhance electrical transport, while defect‐induced lattice softening intensifies phonon scattering and suppresses lattice thermal conductivity.

Terahertz narrow-band filter based on rectangle photonic crystal

, 2016
A terahertz filter with a channel drop cavity and a resonant reflection cavity in a two-dimensional photonic crystal is theoretically proposed. The channel drop cavity is used to trap photons at resonant frequency from the bus waveguide through coupling ...

Link Availability Prediction Framework for Sub-Terahertz Wireless LANs Based on Multi-Band Propagation Information

IEEE Access
This study proposes a link availability prediction framework for sub-terahertz wireless local area networks (LANs). In the sub-terahertz band, to combat severe path loss between an access point (AP) and a station (STA), it is necessary to form a narrow ...
