Figure 5: (a) Partial Γ-X gap map as a function of the PSi layer porosity. On the right 𝑦 axis, equivalent wavelength is indicated for a lattice parameter 𝑎 = 7 μm. (b) Partial Γ-M gap map as a function of the PSi layer porosity. The wavelength on right 𝑦 axis is indicated for a lattice parameter 𝑎 = 7 μm, as the experimental one.
