Boundary tension at the interface of nanoscopic helium films on an heterogeneous substrate
This paper reports the first calculation of the two-dimensional interfacial profile and energetics of nanoscopically thin films of helium, on an heterogeneous planar substrate consisting of two adjoining metals. The calculations are performed in the frame of density functional theory at zero tempera...
