Tight‐binding molecular dynamics simulation of ZnSe liquid within the local environment dependence

Abstract

We investigate the structural, electronic and dynamical properties of ZnSe liquid using tight-binding molecular dynamics (TBMD) simulations. We report the TBMD calculations for the solid and liquid forms of the ZnSe compound. To produce more realistic results the TB model includes the local environment dependence in the Hamiltonian matrix at finite temperature for ZnSe. To further demonstrate the efficiency of the TBMD approach, we present results for finite temperature physical properties of ZnSe liquid. We are able to show good agreement with experiment for the atomic mean-squared displacement and melting point.

Effect of curvature on wetting and dewetting of proboscises of butterflies and moths

“…Lepidoptera are often observed drinking mineral water from the soil by bending their proboscises into a J-configuration with the distal portion pressed to the ground [21][22][23][24]. The physical phenomena that facilitate feeding when the proboscis is bent are unknown [2,[25][26][27]. Generally, in the bent or coiled proboscis, the series of legular plates are prone to open up the interlegular pores [17].…”
