Room Temperature Ferromagnetism in InGaN Nanostructures Induced by Cr+ ion Implantation

open access: yesNanomaterials, 2020
This paper presents the magnetic properties of chrome ion (Cr+) implanted InxGa1−xN (x = 0.1, 0.3, 0.5 and 1.0) nanostructures grown by molecular beam epitaxy (MBE). The Cr+ implantation was conducted at 110 keV with three doses, namely 2.6 × 1015, 5.3 ×

Solid-State Chemistry with Nonmetal Nitrides [PDF]

open access: yes, 1993
Among the nonmetal nitrides, the polymeric binary compounds BN and Si3N4are of particular interest for the development of materials for high-performance applications. The outstanding features of both substances are their thermal, mechanical, and chemical

Overview of the synthesis of MXenes and other ultrathin 2D transition metal carbides and nitrides

open access: yesCurrent opinion in solid state & materials science, 2019
In 2011, a new family of two dimensional (2D) carbides, carbonitrides and nitrides – labeled MXenes – was discovered. Since then the number of papers on these materials has increased exponentially for several reasons amongst them: their hydrophilic ...

Giant excitonic absorption and emission in two-dimensional group-III nitrides [PDF]

open access: yes, 2019
Absorption and emission of pristine-like semiconducting monolayers of BN, AlN, GaN, and InN are here systematically studied by ab-initio methods. We calculate the absorption spectra for in-plane and out-of-plane light polarization including quasiparticle

Double transition-metal MXenes: Atomistic design of two-dimensional carbides and nitrides

open access: yesMRS bulletin, 2020
MXenes are a large family of two-dimensional (2D) transition-metal carbides, nitrides, and carbonitrides. The MXene family has expanded since their original discovery in 2011, and has grown larger with the discovery of ordered double transition-metal ...
