Abstract
We present an analytical model of transient compressive stress evolution during growth of thin films with high surface and grain boundary diffusivities on substrates. The model provides a closed-form analytical solution which compares well with numerical analysis as well as recent experimental data on transient stress evolution during electrodeposition of Sn films on substrates.
