We investigated the contact mechanics of EGaIn droplets on template-stripped gold surfaces functionalized with SAMs (i.e., C4, C6, C8, C10). Alkyl functional groups were chosen because they are known to form stable molecular tunnelling junctions, and the resulting SAM surfaces are smooth with a root-mean-square surface roughness ∆h < 1 nm. The contact angle θ that a droplet makes on the surface depends on the surface energies of the various interfaces, i.e., the Young's relation:
