Dissipation Under the Magnetic Field on 2D Surface

TL;DR

This paper investigates how magnetic fields influence surface diffusion and kinetic energy of molecules, revealing effects on crystal growth and molecular behavior under magnetic influence.

Contribution

It introduces two novel effects of magnetic fields on surface molecules: reduced diffusion of charged ions and decreased kinetic energy of dipolar molecules.

Findings

Magnetic fields decrease ion diffusion constants on crystal surfaces.

Dipolar molecules experience reduced kinetic energy in magnetic fields.

Magnetic effects influence crystal growth dynamics.

Abstract

It is well known that the convection of liquid solution or melt liquid is inhibited by the magnetic field experimentally, and so that we can make the larger and better crystals at the cost of slow growth rate. We shall show here another two effects due to the magnetic field. First, when the ionised molecule diffuses on the surface of crystal under the magnetic field applied normal to the surface,its diffusion constant decreases due to the magnetic effect. Second, even if the molecule has no electric charge, if it has electric dipole moment, the kinetic energy decreases by different mechanism.
