A simple model for the formation of compressive stress in thin films by ion bombardment
TL;DR: In this paper, a simple model was proposed to explain the formation of compressive stress in thin films deposited with simultaneous bombardment by energetic ions or atoms, and it was shown that the stress σ is proportional to [ Y (1-v) ]E 1 2 (R j+kE 5 3 ), where E is the ion energy, R the net depositing flux, j the bombarding flux, k a material dependent parameter, Y the film material Young's modulus and v the Poisson ratio.
