Abstract:
In this paper, an analytical threshold voltage model of double gate-all-around metal-oxide-semiconductorfield-effect-transistors (DGAA MOSFETs) including the fringing field effects is developed. The total fringing capacitance arising due to induced fringing fields in the device is divided into inner, outer and bottom fringing capacitance. A simple expression for each fringe capacitance is developed individually. The 3-D Poisson's equation has been solved in the channel region using the parabolic potential approximation method to develop the surface potential expressions. The effects of fringin

Abstract:
This paper presents a self-consistent analytic model to describe the current-voltage (I-V) and charge-voltage (Q-V) behavior of quasi-ballistic III-nitride transistors. We focus on two types of transistor geometries: (i) high electron mobility transistors (HEMTs) suitable for radio frequency (RF) applications and (ii) nanowire field-effect transistors (FETs) for digital applications. Our core model is based on Landauer transport theory which is combined with the calculation of charge density and velocity of charges at the top-of-the-barrier in the transistor.

In this paper, the effect of the eye field of view (known as F.O.V.) on the performance and quality of the image of the human eye is studied, analyzed, and presented in detail. The image quality of the retinal is numerically analyzed using the eye model of Liou and Brennan with this polymer contact lens. The image, which is in digital form were collected from various sources such as from photos, text structure, manuscripts, and graphics. These images were obtained from scanned documents or from a scene. The color fringing which is chromatic aberration addition to polychromatic effect was studi

Abstract:
The influence of an image charge effect on the impurity-related energies, the oscillator strengths of transitions from the 1s-like state to 2px and 2pz states as well as the optical absorption coefficients in a spherical quantum dot in the presence of an external electric field have been studied. The results show that the image charges lead to significant changes in the optical coefficients of the system.

Abstract:
In this paper, we review liquid-crystal-on-silicon (LCoS) technology and focus on its new application in emerging augmented reality (AR) displays. In the first part, the LCoS working principles of three commonly adopted LC modes—vertical alignment and twist nematic for amplitude modulation, and homogeneous alignment for phase modulation—are introduced and their pros and cons evaluated. In the second part, the fringing field effect is analyzed, and a novel pretilt angle patterning method for suppressing the effect is presented. Moreover, we illustrate how to integrate the LCoS panel in an AR di

Abstract:
In this work, the influence of the underlap region on the electrical behavior of a SOI-nFinFET transistor has been studied with the purpose of radiation sensing. The analysis was performed by evaluating the impact of variations in the underlap region on the on-state current and by studying its sensitivity. The impact of the underlap region on the drain current and, consequently, on the devices’ sensitivity was explained by the analysis of series resistance, the fringing field and electron density. Considering the main impact of radiation in these devices, the study of sensitivity was also perf

AbstractThis paper investigates prospects of utilizing a high-power laser-driven target-normal-sheath-acceleration proton beam for the experimental demonstration of the magnetic self-focusing phenomenon in charged particle beams. In the proposed concept, focusing is achieved by propagating a space-charge dominated ion beam through a stack of thin conducting and grounded foils separated by vacuum gaps. As the beam travels through the system, image charges build up at the foils and generate electric field that counteracts the beam's electrostatic self-field — a dominant force responsible for exp

Abstract:
Massive chiral fields, “left-handed” for fermions and “right-handed” for antifermions, are shown to be a natural prediction of a new approach to the Dirac field theory which in the zero-mass limit spontaneously yields Weyl’s two-component scheme. Such an approach gives an improved theoretical framework to the “standard model”: It accounts for (and clarifies the origin of) the “P-violation” effect, without needing any ad-hoc external prescriptions. A double-faced—either “Dirac” or “chiral” — model of a massive spin[Formula: see text] fermion is involved, due to the internal coexistence of two a
