Near-critical supernova outflows and their neutrino signatures

open access: yesPhysics Letters B, 2022
We demonstrate that the neutrino-driven outflows inside exploding core-collapse supernovae possess a special property of near-criticality, that is, they are on the edge of forming termination shocks.

Step-Double-Zone-JTE for SiC Devices with Increased Tolerance to JTE Dose and Surface Charges

open access: yesMicromachines, 2018
In this paper, an edge termination structure, referred to as step-double-zone junction termination extension (Step-DZ-JTE), is proposed. Step-DZ-JTE further improves the distribution of the electric field (EF) by its own step shape. Step-DZ-JTE and other

Planar Implantation Edge Termination for Vertical GaN Power Devices

open access: yes, 2023
Edge termination plays a crucial role in achieving near-ideal avalanche breakdown in power semiconductor devices. In this paper, two edge termination designs, one GR (guard ring) [1], the other USAB-JTE (ultra-small-Angle bevel junction termination ...

Self-Termination of Borophene Edges

open access: yesJACS Au
Due to boron's unique bonding nature, planar boron materials, including borophenes, boron nanoclusters, and nanoribbons, show very puzzling features, especially the superior stability of the free-standing planar boron edges. Here, we present a systematic investigation of the bonding configurations of various edges of borophene.

Role of hydroxylation for the atomic structure of a non-polar vicinal zinc oxide

open access: yesCommunications Chemistry, 2021
Under-coordinated corner and edge sites often dictate oxide properties, however, information about their atomic-scale structure and chemical nature is often missing. Here, a combined experimental and theoretical study of the ZnO( $$10\bar{1}4$$ 10 1 ¯ 4 )

Cycle-based formulations in Distance Geometry

open access: yesOpen Journal of Mathematical Optimization, 2023
The distance geometry problem asks to find a realization of a given simple edge-weighted graph in a Euclidean space of given dimension $K$, where the edges are realized as straight segments of lengths equal (or as close as possible) to the edge weights ...

Improved radiation detectors on 4H-SiC epilayers by edge termination

open access: yes, 2016
We report the development of an edge termination by depositing thin Si3N4 passivating film on 4H-SiC epilayer based radiation detector. The edge termination method is shown to be very effective for improving both the detector leakage current and ...

Novel edge-termination structures for 1200 V-class SiC devices

open access: yes, 2021
Driven by the markets of electric vehicle (EV), charger, photovoltaic (PV) inverter and power supply, silicon carbide (SiC) power devices have attracted much attention due to the inherent material properties of wide bandgap, high critical electric field,

Implanted Guard Ring Edge Termination With Avalanche Capability for Vertical GaN Devices

open access: yes, 2023
Edge termination is the key building block in power devices to enable near-ideal, avalanche breakdown voltage (BV). This work presents the design, fabrication, and physics of a GaN guard ring (GR) edge termination formed by selective-area nitrogen ...
