Hierarchically Wrinkled Silver Ink as a Platform for Fully Integrated Stretchable Electronic Systems

Advanced Materials Technologies, EarlyView.
Silver Hierarchical Responsive ink (SHRink), a universal approach for the fabrication of highly stretchable interconnects, wirings, and skin‐interfaced electrodes, is realized through low‐cost, scalable spray‐printing and transfer‐printing. The SHRink demonstrates high electrical conductivity (1.2E04 S cm−1) and large stretchability (235% max fracture ...

Continued development of doped-germanium photoconductors for astronomical observations at wavelengths from 30 to 120 micrometers [PDF]

, 1978
The development of doped-germanium detectors which have optimized performance in the 30- to 120-mu m wavelength range and are capable of achieving the objectives of the infrared astronomical satellite (IRAS) space mission is discussed.

Transforming DIY Geiger Counter Kits into Muon Detectors for Education and Scientific Exploration

Particles
Any Geiger counter can be used as an effective cosmic ray detector on its own. In fact, it is known that even in the absence of a radioactive source, the instrument detects what is known as background radiation, which consists of various types of ...

Dielectric Permittivity Tensor of Muscovite for Next Generation All Van Der Waals Broadband Photonic Components

Advanced Optical Materials, EarlyView.
Low‐index and low‐loss vdW muscovite represents an emerging robust dielectric platform for the creation of next‐generation all‐vdW nanophotonic architectures. Its utilization as a low‐index building‐block in all‐vdW multilayers enables extreme optical contrast when paired with MoS2, paving the way to the realization of few‐layer ultrathin DBS ...

Low dark current Sb-based short-wavelength infrared photodetector

AIP Advances
We have theoretically and experimentally demonstrated the feasibility of achieving ultra-low dark current in CpBnn type detectors based on a double-barrier InAs/GaSb/AlSb type-II superlattice. By employing a structure that separates the absorption region

Pointlike Material Accumulation and Displacement in Azopolymer Thin Films Driven by Spatial Light Modulation

Advanced Optical Materials, EarlyView.
A maskless, SLM‐driven approach enables the deterministic inscription of arbitrary topographical features in azopolymer films by mapping complex vectorial light fields onto local viscoplastic stress. This platform allows for the rapid generation and dynamic erasure of high‐aspect‐ratio micro‐spikes, offering a versatile tool for reconfigurable flat ...
