Perturbation Analysis of 1D Cahn Hilliard Equations in Thin Films Using Green Functions
Abstract

The paper investigates the phase separation dynamics in thin films using onedimensional Cahn-Hilliard equation. It focuses on the development of perturbation solutions for Green functions under various boundary conditions, specifically periodic, Neumann and Dirichlet. The derived solutions provide insights into the behavior of concentration profiles, essential for understanding the phase separation process in technologically relevant thin film materials.

Introduction

Thin films are widely used in various technological applications, including microelectronics and energy storage. Phase separation within these films is critical to their performance and properties.
