Strong Repulsive Lifshitz-van der Waals Forces on Suspended Graphene
Gianluca Vagli, Tian Tian, Franzisca Naef +4
Understanding surface forces of two-dimensional (2D) materials is of fundamental importance as they govern molecular dynamics and atomic deposition in nanoscale proximity. Despite…

Solid-State Lifshitz-van der Waals Repulsion through Two-Dimensional Materials
Tian Tian, Gianluca Vagli, Franzisca Naef +7
In the 1960s, Lifshitz et al. predicted that quantum fluctuations can change the van der Waals (vdW) interactions from attraction to repulsion. However, the vdW repulsion, or its l…
