Two‐dimensional Carrier Transport in Si MOSFETs
VLSI Design, Volume 8, Issue 1-4, Page 1-11, 1998., 1998 The importance of 2‐dimensional (2D) features of carriers in Si MOSFETs on the device performance is re‐examined experimentally and theoretically from the viewpoint of low‐field mobility, velocity in high tangential fields and the inversion‐layer capacitance. It is confirmed that low‐field mobility and inversion‐layer capacitance can be understood well

Novel transport phenomena in graphene induced by strong spin-orbit interaction [PDF]
arXiv, 2021 Graphene is known to have small intrinsic spin-orbit Interaction (SOI). In this review, we demonstrate that SOIs in graphene can be strongly enhanced by proximity effect when graphene is deposited on the top of transition metal dichalcogenides. We discuss the symmetry of the induced SOIs and differences between TMD underlayers in the capacity of ...

Ultra-thin silicon-on-insulator waveguide bend based on truncated Eaton lens implemented by varying the guiding layer thickness [PDF]
, 2020 Silicon-on-insulator (SOI) waveguides with different geometries have been employed to design various integrated optical components. Reducing the bending radius of the SOI waveguides with low bending loss is essential in minimizing the footprint of light-wave circuits. The propagating mode is less confined in the core of the ultra-thin SOI waveguide and

Design and fabrication of SOI micro-ring resonators based on sub-wavelength grating waveguides.
Optics Express, 2015 Standard silicon photonic strip waveguides offer a high intrinsic refractive index contrast; this permits strong light confinement, leading to compact bends, which in turn facilitates the fabrication of devices with small footprints.

Superconductivity protected by spin-valley locking in ion-gated MoS2 [PDF]
, 2015 Symmetry-breaking has been known to play a key role in noncentrosymmetric superconductors with strong spin-orbit-interaction (SOI). The studies, however, have been so far mainly focused on a particular type of SOI, known as Rashba SOI, whereby the ...

A Monolithic active pixel sensor for ionizing radiation using a 180nm HV-SOI process [PDF]
, 2014 An improved SOI-MAPS (Silicon On Insulator Monolithic Active Pixel Sensor) for ionizing radiation based on thick-film High Voltage SOI technology (HV-SOI) has been developed. Similar to existing Fully Depleted SOI-based (FD-SOI) MAPS, a buried silicon oxide inter-dielectric (BOX) layer is used to separate the CMOS electronics from the handle wafer ...

Optimising apodized grating couplers in a pure SOI platform to -0.5 dB coupling efficiency.
Optics Express, 2015 We present a theoretical optimisation of 1D apodized grating couplers in a "pure" Silicon-On-Insulator (SOI) architecture, i.e. without any bottom reflector element, by means of a general mutative method.
