Article Synopsis
- * The research highlights that both the nucleation and growth stages of the ZnS films are significantly affected by the type of Zn precursor used, and emphasizes the importance of early film formation stages on overall film quality.
- * Techniques like X-ray photoelectron spectroscopy and transmission electron microscopy reveal that increased surface oxidation during the early stages can prevent solution desorption, and an analysis of crack formation provides insights into the growth process of the films based on different precursors.
Silver thin film mirrors are attractive candidates for use as specular back reflectors to enhance broadband light absorption via strong optical interference in ultrathin film semiconductor photoabsorbers. However, deposition of metal-oxide absorbers often requires exposure to high temperature in an oxygen atmosphere, conditions that cause thermal etching and degrade the specular reflectance of silver films. Here, we overcome this challenge and demonstrate that epitaxial growth of silver mitigates thermal etching under the high-temperature oxygen-containing environments that cause polycrystalline films to degrade.
