高压下玻璃碳的结构和性质
Structure and Properties of Glassy Carbon under High Pressure
摘要
Abstract
Glassy carbon is a nearly fully sp2-bonded amorphous carbon allotrope.Its highly disordered atomic structure and isotropic nature make it an ideal model system for studying pressure-induced transitions in amorphous materials and a versatile precursor for the synthesis of novel amorphous carbon materials.This review summarizes recent advances in understanding the structural transformations,property evolution,and transition mechanisms of glassy carbon under high-pressure and high-pressure-high-temperature(HPHT)conditions,as well as its emerging applications in high-pressure science.Experimental and theoretical studies have shown that glassy carbon undergoes a pressure-induced sp2 to sp3 bonding transition,forming a tetrahedral amorphous carbon phase with high transparency,electrical resistivity,strength,and bulk modulus.Although this high-pressure phase is not recoverable at ambient conditions,HPHT treatment can produce new amorphous carbon materials,including compressed glassy carbon and nearly fully sp3-bonded amorphous diamond.In addition,the unique nano-pore structure of glassy carbon and its pressure-induced permeability have enabled the development of nanostructured diamond capsules capable of preserving high-pressure phases at ambient conditions.This capability opens new opportunities for high-pressure research and for the practical utilization of high-pressure materials beyond the confines of high-pressure apparatus.关键词
