Effect of Carbon Concentration on the Sputtering of Carbon-Rich SiC Bombarded by Helium Ions

open access: yesComputation, 2018
Silicon carbide (SiC) is considered as an important material for nuclear engineering due to its excellent properties. Changing the carbon content in SiC can regulate and control its elastic and thermodynamic properties, but a simulation study of the ...

A note on non-canonical passives : the case of the get-passive [PDF]

open access: yes, 2008
In many languages, a passive-like meaning may be obtained through a noncanonical passive construction. The get passive (1b) in English, the se faire passive (2b) in French and the kriegen passive (3b) in German represent typical manifestations.

Fundamental studies of passivity and passivity breakdown [PDF]

open access: yes, 1992
We developed and experimentally tested physical models for growth and breakdown of passive films on metal surfaces. These models are ``point defect models,`` in which the growth and breakdown are described in terms of movement of anion and cation vacancies.

Pd-Induced Electronic Activation and Strain-Tunable Adsorption-Coupled Electronic Modulation in Janus ZrSSe Monolayers

open access: yesElectronic Materials
Pd-decorated Janus ZrSSe monolayers provide a promising platform for adsorption-coupled electronic modulation in two-dimensional materials. Using first-principles density functional theory, we systematically investigate the structural stability ...
