• lower process temperatures [9]. In addition, the Ge exciton Bohr radius (≈24 nm) is significantly larger than that of Si (≈4.5 nm), allowing for quantum effects to appear in nanostructures exhibiting larger sizes [10], and allowing the k-selection rules to be broken. For example, lasing has only been

The gap between such ideal models, which provide insight into quantum effects, and real scale systems is difficult to bridge, but there have been some attempts at building multi-scale modeling frameworks [43]. Still, there is ample room for development in the modeling of growth, interaction with

• proton motion is usually small so that proton tunneling is less important than in many other cases. However, there is evidence for quantum effects due to the delocalized nature of the protons, in particular from ab initio MD simulations [4][36][37]. Such calculations show that an adequate incorporation

According to estimates we made in [17] the surface charge densities used in our computer simulations falls within the range of hydrogen underpotential deposition (UPD). In

• because in experiments all vertices will show some natural rounding and even if very large curvatures could be realized, ultra-high field enhancement is unphysical on a scale below 1 nm because of nonlocality and quantum effects [61][62]. We used blended edges with radii of curvature Rblend = 5 nm. The
