Toughening β‐Ga2O3 via Mechanically Seeded Dislocations

open access: yesAdvanced Functional Materials, EarlyView.
β‐Ga2O3 is promising for next‐generation semiconductors but its brittleness limits flexible and high‐precision applications. Here, mechanically seeded dislocations introduced by surface deformation improved damage tolerance in (001) β‐Ga2O3. Nanoindentation and characterization show dislocations suppress cleavage cracks by enabling stable plastic ...

Triple‐Bond Covalent Radii

Chemistry – A European Journal, 2005
AbstractA system of additive covalent radii is proposed for σ2 π4 triple bonds involving elements from Be to E 112 (eka‐mercury). Borderline cases with weak multiple bonding are included. Only the elements in Group 1, the elements Zn–Hg in Group 12 and Ne in Group 18 are then totally excluded. Gaps are left at late actinides and some lanthanides.

Classical covalent bond

American Journal of Physics, 1975
In an introductory physics course one of the student computer projects provided a clear demonstration of how the covalent bond, the fundamental bond of organic chemistry and biology, arises directly from Coulomb’s law. Since the project was carried out by a student whose study of physics consisted of only one semester of Newtonian mechanics, the ...

Orbital contraction and covalent bonding

The Journal of Chemical Physics, 2022
According to Ruedenberg’s classic treatise on the theory of chemical bonding [K. Ruedenberg, Rev. Mod. Phys. 34, 326–376 (1962)], orbital contraction is an integral consequence of covalent bonding. While the concept is clear, its quantification by quantum chemical calculations is not straightforward, except for the simplest of molecules, such as H2 ...
