Anomalous strain-dependent thermal conductivity in superelastic screw-dislocated graphites
Yu Li, Zhiqiang Zhao, Zhuhua Zhang +2
The design of strain-stable, or even strain-enhanced thermal transport materials is critical for stable operation of high-performance electronic devices. However, most nanomaterial…
