Uniqueness of Borophene and its Exceptional Properties for Advance Application-A Review

Borophene, a two-dimensional (2D) allotrope of boron, has garnered significant attention due to its unique structural, electronic, and mechanical properties, which make it a promising material for applications in electronics, energy storage, and catalysis. This review provides a comprehensive overview of the current state of borophene synthesis, focusing on various methods such as chemical vapor deposition (CVD), molecular beam epitaxy (MBE), and liquid-phase exfoliation. Despite its potential, borophene faces significant challenges related to instability, which limits its practical applications. The review highlights the primary causes of this instability, including surface oxidation, phase transitions, and the inherent reactivity of boron. We also explore various strategies to mitigate these issues, such as surface passivation, alloying with other elements, and the optimization of growth conditions. Additionally, the effects of substrate choice and the interaction between borophene and underlying materials are examined, revealing their critical role in stabilizing the 2D structure. Finally, the growth mechanisms of borophene are discussed, providing insights into the formation of its unique structures and the underlying principles that govern its growth on different substrates. This review aims to serve as a valuable resource for researchers seeking to advance the development and application of borophene in various technological fields.
