Discovering Shared Design Heritage for Semiconductor‐Based Gamma‐Ray Spectrometers: From CdTe to Metal Halide Perovskites

open access: yesLaser &Photonics Reviews, EarlyView.
Decades of CdTe and CdZnTe gamma‐ray spectrometer development define core design principles for room‐temperature semiconductor detectors. This Review highlights how metal halide perovskites rapidly assimilate these principles, particularly through defect and compositional engineering strategies that establish favorable spectroscopic conditions for ...

Strategy for One‐Step Optimization of Metal Oxide Passivating Contact Materials for Si Heterojunction Solar Cells through Growth Angle Variation

open access: yesSmall, EarlyView.
A one‐step oblique angle reactive sputtering approach enables simultaneous tuning of bulk and interfacial stoichiometry in a metal oxide/ silicon heterojunction. In case of vanadium oxides, growth angle variation controls the formation of stoichiometric SiO2, ternary SiOx(V) interlayer, and phase purity of vanadium oxide, considerably simplifying the ...

Preventing Plasma‐Induced Resist Hardening in Molybdenum Disulfide Transistors via Sacrificial Metal Mask Lithography

open access: yesSmall, EarlyView.
Photoresist (PR) residue significantly degrades the electrical performance of 2D semiconductors such as MoS2. In particular, the intrinsically ultrathin nature of these materials makes them highly susceptible to damage during conventional PR cleaning procedures.

The impact of the coupling relationship between projectile size and yarn dimension on the ballistic performance of plain weave fabric

open access: yesDefence Technology
Aramid fibers, due to their relatively high inter-yarn friction, high strength, high modulus, and other characteristics, have become a typical representative of flexible anti-ballistic materials in modern warfare. Current research on the anti-penetration

Molecular Friction Trumps Viscosity in Angstrofluidic Transport

open access: yesSmall, EarlyView.
Single‐file transport through sub‐1 nm graphene nanopore and carbon nanotube is investigated using molecular dynamics and ergodic trajectory sampling. The study shows that confinement geometry and wall‐fluid interaction strength govern molecular mobility, allowing atomistic motion to be translated into a continuum‐based resistance coefficient for ...
