Abstract

Low or zero thermal expansion (ZTE) materials aresuitable for applications requiring low dimensional changes tinder large temperatrire variations. Using density functional theoty calculations and classical molecular dynartrits, simulations, we demonstrate that tailoring the density of covalent carbon-carbon interlayer bonds in bilayer,graphene tunes its thermal expansion coefficient from negative to positive values at room temperature and, most exciting, causes it to exhibit ZTE behavior in a wide range of temperatures.
