Low-Loss Narrowband Filtering Switch Based on Coaxial Resonators
IEEE Access, 2018 In this paper, a narrowband filtering switch with low loss and high selectivity is presented based on coaxial resonators for the first time. PIN diodes mounted on the printed circuit boards are embedded into a coaxial filter to enable ON and OFF states ...

Ultrafast GaAs microwave PIN diode
Electronics Letters, 1983 This letter describes what is believed to be the first successful realisation of GaAs PIN diodes. The vertical structure was grown on an n+ substrate by MOCVD of a 2 μm, 1015 cm−3 unintentionally doped n− layer followed by a 0.3 μm, 4×1019 cm−3 Zn doped p+ layer. The isolation and insertion loss of a single shunt-mounted device are typically −27 dB and

Advanced Functional Materials, EarlyView.Ferroelectricity in thin HfO2‐based films offers great possibilities for next‐generation neuromorphic memory devices. There, the response to subcoercive voltage signals is driven by the movement of mobile interfaces and their interaction with crystal defects – a yet rather unexplored aspect, which we shed light on and gain new insights into the complex

A simple device for the measurement of kerma based on commercial PIN photo diodes
EPJ Web of Conferences, 2012 The development of a dose reader for the measurement of the radiation dose from neutron and ionizing radiation is presented. The dose reader (kerma meter) is using as active element commercial PIN diodes with long base, which can provide a maximal ...

Operating principles of pin diodes
Electrical Engineering in Japan, 2007 AbstractAnalytical models of the pin diode in a small‐current operation are not known yet. This article presents a simple analytical model of the pin diode operation with its confirmation by a numerical simulation. At the onset, carrier recombinations are not included for the sake of simplicity. The exact JF−VF characteristic $[J_{F} \propto \hbox{exp}(

Toughening β‐Ga2O3 via Mechanically Seeded Dislocations
Advanced Functional Materials, EarlyView.β‐Ga2O3 is promising for next‐generation semiconductors but its brittleness limits flexible and high‐precision applications. Here, mechanically seeded dislocations introduced by surface deformation improved damage tolerance in (001) β‐Ga2O3. Nanoindentation and characterization show dislocations suppress cleavage cracks by enabling stable plastic ...
