Vacancy Defects in Bulk and Quasi-Bulk GaN Crystals [PDF]

Crystals, 2022
In-grown vacancy defects in bulk and quasi-bulk GaN crystals have been extensively studied with positron annihilation spectroscopy. High concentrations of Ga-vacancy-related defects are found irrespective of the growth method used in crystals with a high

Toughening 3D-printed Zr-based bulk metallic glass via synergistic defects engineering

Materials Research Letters, 2022
3D printing provides a novel approach to fabricate bulk metallic glass components without limitations in size and geometry. However, defects (porosity and partial crystallization) are inevitable, which are detrimental to mechanical properties.

A Numerically Efficient Method to Assess the Elastic–Plastic Strain Energy Density of Notched and Imperfective Cast Steel Components

Applied Mechanics, 2023
The fatigue strength of cast steel components is severely affected by manufacturing process-based bulk and surface imperfections. As these defect structures possess an arbitrary spatial shape, the utilization of local assessment methods is encouraged to ...

MAPbI3-on-CuInSe2 two-terminal monolithically integrated and four-terminal mechanically stacked tandem solar cells: A Theoretical Investigation Using SCAPS-1D

Results in Optics, 2023
Two-terminal (2-T) and four-terminal (4-T) tandem solar cells with wide bandgap perovskite (MAPbI3) as the top sub-cell and low bandgap copper indium diselenide (CuInSe2, CIS) as the bottom sub-cell have potential to outperform the single-junction power ...

Realizing IR theories by projections in the UV

Journal of High Energy Physics, 2020
We show how (topologically twisted) quantum field theories in the IR of bulk RG flows can be represented within the respective UV theories by means of codimenion- one projection defects.
