Comprehensive Review on Adsorption Behaviors of Bromine

Abstract

Phases and thin films have been an interesting topic in the world of materials science. Adsorption of an adatom on a substrate result in exceptional properties than the bulk phase, its deposition often performed in ultra-high vacuum. These extraordinary physical, chemical and electronic properties find applications in solar cells, sensors, metal interconnects of circuits, protective coatings and spintronic devices. Halogens have been widely studied for their metal etching reactions. This study provides a review of bromine adsorption on different substrates. The adsorption has resulted in many phases and reconstructions, studied using scanning tunnelling microscopy, low energy electron diffraction and density functional theory. Understanding the formation and dissociation of bromine phases provides a crucial insight about how bromine behaves at atomic levels and can result in improvement in the power conversion efficiency and junction quality of solar cells and metal interconnects.
