Query: Impacts of Atomistic Coating on Thermal Conductivity of Germanium
  Nanowires   By using non-equilibrium molecular dynamics simulations, we demonstrated that
thermal conductivity of Germanium nanowires can be reduced more than 25% at
room temperature by atomistic coating. There is a critical coating thickness
beyond which thermal conductivity of the coated nanowire is larger than that of
the host nanowire. The diameter dependent critical coating thickness and
minimum thermal conductivity are explored. Moreover, we found that interface
roughness can induce further reduction of thermal conductivity in coated
nanowires. From the vibrational eigen-mode analysis, it is found that coating
induces localization for low frequency phonons, while interface roughness
localizes the high frequency phonons. Our results provide an available approach
to tune thermal conductivity of nanowires by atomic layer coating.
