N2 - This paper investigates the combined effects of surface stiffness κ and wall particles' mass mw on the slip length. It aims to enhance our understanding of the momentum and energy transfer across solid-liquid interfaces. Elastic spring potentials are employed to simulate the thermal solid walls and model the surface stiffness κ. The thermal oscillation amplitude is primarily dictated by values of stiffness, whereas the oscillating frequency is proportional to √κ/mw. It is shown that for cases with variable wall mass the relation of slip length and thermal oscillating frequencies can be approximated by a "master" curve according to which the length initially increases, then approaches a peak value, and afterwards is reduced toward an asymptotic value.
