Extraordinary mechanical performance in charged carbyne
文献摘要：
Carbyne,the linear chain of carbon,promises the strongest and toughest material but possesses a Peierls instability(alternating single-bonds and triple-bonds)that reduces its strength and toughness.Herein,we computationally found that the gravimetric strength,strain-to-failure,and gravimetric toughness can be improved from 74 GPa·g-1·cm3,18％,and 9.4 kJ·g-1 for pristine carbyne to the highest values of 106 GPa·g-1·cm3,26％,and 19.0 kJ·g-1 for carbyne upon hole injection of+0.07 e/atom,indicating the charged carbyne with record-breaking mechanical performance.Based on the analyses of the atomic and electronic structures,the underlying mechanism behind the record-breaking mechanical performance was revealed as the suppressed and even eliminated bond alternation of carbyne upon charge injection.
