Edge modes in finite-size systems with different edge terminals
Chinese Physics BAbstract We investigate the behavior of edge modes in the presence of different edge terminations and long-range (LR) hopping. Here, we mainly focus on such model crystals with two different types of structures (type I: “…–P–Q–P–Q–…” and type II: “… = P–Q = P–Q = …”), where P and Q represent crystal lines (CLs), while the symbols “–” and

Edge termination strategies for a 4kV 4H–SiC thyristor
Solid-State Electronics, 2006Abstract Thyristors able to block 4 kV have been fabricated and characterised. The experimental forward current is 1.3 A @ VAK = 10 V for a 9 mA gate current during 550 ns. The device active area is 2.3 mm2. The devices and their edge terminations have been designed using numerical simulations.

A Study on Delaunay Terminal Edge Method
2007The Delaunay terminal edge algorithm for triangulation improvement proceeds by iterative Lepp selection of a point M which is midpoint of a Delaunay terminal edge in the mesh. The longest edge bisection of the associated terminal triangles (sharing the terminal edge) can be seen as a first step in the Delaunay insertion of M . The method was introduced

Computer simulation of edge-terminated carbon nanoribbons
Bulletin of the Lebedev Physics Institute, 2017In this paper, we present the results of ab initio simulation of edge-terminated carbon nanoribbons (CNRs). The calculations were performed using the electron density functional theory with the expansion of electron wave functions in plane waves in the Quantum Espresso software package [1].

Suppression of edge delamination in composite laminates by terminating a critical ply near the edges
29th Structures, Structural Dynamics and Materials Conference, 1988W. S. Chan* Bell Helicopter Textron, Inc. Fort Worth, Texas 0.0. Ochoa' Texas A&M University College Station, Texas The termination of a critical ply a small distance away from the free edge of laminates has been shown to be effective in suppressing delamination a t the edges.

Geometric and electronic structures of sulfur-edge-terminated zigzag edge graphene nanoribbons
Physica E: Low-dimensional Systems and Nanostructures, 2013Abstract The stable geometric and electronic structures of the fully and half sulfur-edge-functionalized ZGNRs at their widths of four zigzag carbon chains (S-4-ZGNRs) have been studied by using the ab initio density-functional method. It is found from our calculations that (1) under the periodic boundary condition, the two-dimensional plane ...

Edging: From Terminals to Interfaces
This chapter explores edges and their significance in understanding the complex nature of platforms. Rather than being mere lines of demarcation, platform edges are presented as zones of fusion where different elements and practices converge. The chapter begins by exploring the historical evolution of platform edges through the lens of Amazon’s ...openaire +1 more source
