Electrothermally-Actuated Micromirrors with Bimorph Actuators—Bending-Type and Torsion-Type

Sensors, 2015
Three different electrothermally-actuated MEMS micromirrors with Cr/Au-Si bimorph actuators are proposed. The devices are fabricated with the SOIMUMPs process developed by MEMSCAP, Inc. (Durham, NC, USA).

Suitability of applying ultrathin SOI‐based PIN diodes to photodetection of UV wavelength

Electronics Letters
This work intends to investigate the impact of silicon layer thickness and substrate biasing on the UV photodetection efficiency of PIN diodes fabricated with ultra‐thin body and buried oxide (UTBB silicon‐on‐insulator [SOI]) technology, aiming to verify

Enhanced Sensitivity of Silicon-On-Insulator Surface Plasmon Interferometer With Additional Silicon Layer

IEEE Photonics Journal, 2011
It is theoretically found that by adding a thin silicon layer (35 nm) on top of our previously proposed surface plasmon interference (SPI) biosensor in silicon on insulator (SOI), a sensitivity enhancement of up to 2500 nm/refractive index units (RIUs ...

Silicon on insulator MESFETs for RF amplifiers [PDF]

Solid-State Electronics, 2010
CMOS compatible, high voltage SOI MESFETs have been fabricated using a standard 3.3V CMOS process without any changes to the process flow. A 0.6μm gate length device operates with a cut-off frequency of 7.3GHz and a maximum oscillation frequency of 21GHz.

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

High-Power-Compatible Thick Silicon-on-Insulator Waveguide: An Implementation in Optical Phased Array

IEEE Photonics Journal
High-power transmission capability is a critical yet insufficiently explored frontier in integrated photonics. Owing to the restricted optical cross-sectional area of the 220 nm-thick silicon layer, conventional SOI platform is incapable of managing the ...

Effect of Gate Dielectric Material on the Electrical Properties of MoSe₂-Based Metal–Insulator–Semiconductor Field-Effect Transistor

Crystals, 2022
In this study, we fabricated metal–insulator–semiconductor field-effect transistors (MISFETs) based on nanolayered molybdenum diselenide (MoSe2) using two insulator materials, silicon dioxide (SiO2) and silicon nitride (SiN).

Nondestructive Testing of Welded Composite Metal Foams

Advanced Engineering Materials, EarlyView.
X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.
