Predicting a two-dimensional P2S3 monolayer: A global minimum structure

Mechanical behaviour of motion for the two-dimensional monolayer system‎

‎In this paper we study the dynamics of the 2D-motion of a particle of monolayer‎. First we consider the usual physical time component and the plan manifold R2, having the polar coordinates. Then a geometric approach to nonholonomic constrained mechanical systems is applied to a problem from the two dimensional geometric dynamics of the Langmuir-Blodgett monolayer‎. We consider a constraint sub...

A Novel Structure for Optical Channel Drop Filter using Two-Dimensional Photonic Crystals with Square Lattice

In the present paper a novel structure for optical channel drop filter (CDF) based on photonic crystal ring resonator with circular core has been proposed. In order to design the proposed CDF, the plan wave expansion (PWE) method is applied for calculation of band structure and photonic band gap while the transmission characteristics of proposed CDF have been calculated using the finite differe...

Microscopic model for spreading of a two-dimensional monolayer

We study the behavior of a monolayer, which occupies initially a bounded region on an ideal crystalline surface and then evolves in time due to random hopping of the monolayer particles. In the case when the initially occupied region is the half-plane X ≤ 0, we determine explicitly, in terms of an analytically solvable mean-field-type approximation, the mean displacement X(t) of the monolayer e...
