Discovery of carbon-based strongest and hardest amorphous material
文献摘要:
Carbon is one of the most fascinating elements due to its structurally diverse allotropic forms stemming from its bonding varieties (sp,sp2 and sp3).Exploring new forms of carbon has been the eternal theme of scientific research.Herein,we report on amorphous (AM) carbon materials with a high fraction of sp3 bonding recovered from compression offullerene C60 under high pressure and high temperature,previously unexplored.Analysis ofphotoluminescence and absorption spectra demonstrates that they are semiconducting with a bandgap range of 1.5-2.2 eV,comparable to that of widely used AM silicon.Comprehensive mechanical tests demonstrate that synthesized AM-Ⅲ carbon is the hardest and strongest AM material known to date,and can scratch diamond crystal and approach its strength.The produced AM carbon materials combine outstanding mechanical and electronic properties,and may potentially be used in photovoltaic applications that require ultrahigh strength and wear resistance.
