论文摘要
我们通过连续弹性理论解决了范德华键入双层的滑动热力学。我们将最近在H-BN和WTE2双层中观察到的铁电性的鲁棒性归因于大型单层内刚度。我们计算平均场自一致的语音近似中的电敏感性和比热。我们将临界温度和电动开关场与观测值进行比较。
We address the sliding thermodynamics of van der Waals-bonded bilayers by the continuum elasticity theory. We attribute the robustness of the ferroelectricity recently observed in h-BN and WTe2 bilayers to large monolayer in-plane stiffness. We compute the electric susceptibility and specific heat in the mean-field self-consistent phonon approximation. We compare critical temperatures and electric switching fields with the observations.
