Recent Research Progress of Antimony-Based Two-Dimensional Materials for Electronics and Optoelectronics

Two-dimensional (2D) materials, with their atomic-layer thickness and exceptional properties, have garnered significant attention for next-generation integrated circuits. Among these, 2D antimony (Sb)-based materials distinguish themselves through outstanding physical properties, natural abundance, and remarkable stability. Despite their potential, a comprehensive review summarizing advancements in 2D Sb-based materials remains absent. This review addresses this critical gap by presenting an in-depth analysis of recent progress in 2D Sb-based materials, specifically, antimonene, antimony chalcogenides (Sb₂X₃, X = S, Se, Te), antimony oxides (α-, β-, and γ-Sb₂O₃, and SbO_1.93), antimonides (e.g., NdSb₂), and complex polycompounds such as quaternary CdSb₂Se₃Br₂, focusing on their crystal structures, synthesis techniques, applications, and future prospects. By providing valuable insights into the potential of 2D Sb-based materials, our review aims to inspire further research into their practical applications and address the challenges that lie ahead for future electronics and optoelectronics.
