Electric field modulation in the auxetic effect of BP-analog monolayer As and Sb by first-principles calculations

Abstract

Tunable auxetic properties of BP-analog monolayer As and Sb via electric field modulation.

Non-auxetic/auxetic transitions inducing modifications of the magnetic anisotropy in CoFe2O4 thin films

“…compression) in the direction transverse to the load [1]. Such materials have gained considerable interest from the scientific community over the last decade thanks to their potential applications as stents [2], orthopedic bone plates [3] or skin grafts [4] in medicine, as energy absorbers in sports [5] or crashworthiness situations [6,7], as high sensitivity sensors [8,9], or as highly tunable molecular sieves [10]. The archetype of the auxetic structure is the re-entrant honeycomb network, thanks to its peculiarly designed porosity [6,[11][12][13].…”

Comment on “Electrical Switch of Poisson’s Ratio in IV–VI Monolayers via Pseudophase Transitions”

“…The effect of an electric field on Poisson’s ratio was investigated in ref for As and Sb monolayers as well as in ref for IV–VI semiconductor monolayers using first-principles calculations. It was claimed that the electric field can significantly modulate Poisson’s ratio, e.g., by a factor of two in the case of the SiS monolayer when the strength of the electric field increases from 0 to 4 V/nm.…”
