Mapping the surface phase diagram of GaAs(001) using droplet epitaxy [PDF]
, 2019 We combine droplet epitaxy with low-energy electron microscopy imaging techniques to map the surface phase diagram of GaAs(001). The phase patterns produced in droplet epitaxy are interpreted using a simple model which links the spatial coordinates of ...

Zinc Sulfide Enabling Remarkable Surface Passivation of Crystalline Silicon
Advanced Energy Materials, EarlyView.Polycrystalline ZnS films capped by Al2O3 provide outstanding surface passivation performance. The excellent lattice agreement between c‐Si and ZnS combined with a hydrogenation step result in extremely low interface state density (≈ 1×1010 cm−2 eV−1) and recombination current pre‐factor (1.0 fA/cm2), revealing a new passivation strategy for ...
