## Description

- description: We prepare suspended high-quality atomically thin BN without polymer
    contamination to reveal their intrinsic k values and the thickness effect on phonon
    scattering. It is found that k of atomically thin BN measured by optothermal Raman
    technique increases with reduced thickness, i.e. 733±157, 605±132, 526±97 W/mK
    for 1-3L BN, respectively. In addition, for the first time we experimentally measured
    the thermal expansion coefficients (TECs) of 1-3L BN at 300-400 K, which are compared
    with ab initio density functional theory (DFT) calculations in a wider range of
    temperatures. This study indicates that atomically thin BN is one of the best
    electrically-insulating thermal conductors and a promising candidate for heat
    dissipation applications.
