Figure 3

Reduced X-ray scattering-length density (xSLD) profiles, ρ(z)/ρSi, calculated for the VSD:POPC membrane tethered to the surface of a SiGeSi multilayer substrate (upper left) and the OTS:POPC hybrid bilayer tethered to the surface of a SiGeSi multilayer substrate (upper right), each at a transmembrane potential of 0 mV. The profile of the multilayer substrate occurs for z < 0 Å (see Figure S2 of the Supporting Information, for example). The respective difference reduced xSLD profiles, Δρ(z)/ρSi for each case are shown in the panels below for the pairs of potentials indicated.
