Drag of electron–hole bilayer in silicon-on-insulator metal-oxide-semiconductor field-effect transistor at low temperature

Applied Physics Express
Drag between the electron and the hole layers formed in a silicon-on-insulator MOSFET, with the estimated interlayer distance as small as 18 nm, is investigated.

Lasing in silicon–organic hybrid waveguides

Nature Communications, 2016
On-chip light sources for silicon photonic circuits remain a challenge since the indirect bandgap of silicon prevents efficient light emission. The authors demonstrate that lasing can be achieved by combining standard silicon-on-insulator waveguides with

High-extinction-ratio TE/TM selective Bragg grating filters on silicon-on-insulator [PDF]

, 2016
We report on the design and fabrication of TE and TM polarization selective Bragg grating filters in the form of sinusoidal perturbations on the waveguide sidewall and etched holes on the top of the waveguide, respectively.

Silicon-on-insulator ‘HRes’ circuit

Electronics Letters, 1994
Retinal circuits in bulk CMOS are complicated by the need to compensate for the back-gate effect. However, partially depleted silicon-on-insulator devices have a greatly reduced back-gate effect compared to bulk CMOS. Silicon retinae implemented using SOI technology would therefore be smaller and simpler than the bulk CMOS equivalent.

Metal‐Organic Framework Embedded Electrospun Fibrous Membranes‐Based Hybrid Nanogenerators with Hierarchical Modified Polyamide Films for Mechanical Energy Harvesting and IoT Applications

Advanced Functional Materials, EarlyView.
Hybrid nanogenerator (HNG) based on a zinc‐metal‐organic framework‐loaded fibrous film integrated with a hierarchically modified nylon film having micropatterns and micropores is fabricated via an electrospinning technique, and its electrical properties are optimized. The HNGs are incorporated into wearable garments and automobile systems for practical

Towards spin injection from silicon into topological insulators: Schottky barrier between Si and Bi2Se3

, 2012
A scheme is proposed to electrically measure the spin-momentum coupling in the topological insulator surface state by injection of spin polarized electrons from silicon. As a first approach, devices were fabricated consisting of thin (

Double Helical Plasmonic Antennas

Advanced Functional Materials, EarlyView.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

A Novel p-LDMOS Additionally Conducting Electrons by Control ICs

IEEE Journal of the Electron Devices Society, 2019
A silicon-on-insulator (SOI) p-channel lateral double-diffused MOSFET (p-LDMOS), conducting not only holes but also electrons, is proposed and investigated by TCAD simulations. Its most important advantage is the greatly improved relationship between the

Defect Grating Simulations: Perturbations with AFM-like Tips [PDF]

, 2006
A defect grating in a silicon on insulator waveguide is simulated. We consider spectral changes in the optical transmission when a thin silicon nitride or silicon tip is scanned across the defect.
