dc.description.resumoThe formation of hydrogen overlayers on the Zn-terminated ZnO(0001) surface has been reexamined by angle-resolved photoemission spectroscopy (ARPES). While low-energy electron diffraction patterns display the same (1 × 1) symmetry for different surface preparations, the electronic structure feature close to the Fermi level shows the formation of electron pockets, compatible with hydrogen-induced metallic states. Using ARPES and density functional theory (DFT) calculations, we show that hydrogen adspecies can also lead to metallization of this zinc-oxide surface in a similar manner as observed previously on ZnO(10¯10) and O-terminated ZnO(000¯1). Importantly, our DFT calculations indicate that these electron pockets are formed by sp hybridized states and therefore the angular distribution of the emitted photoelectron is significantly suppressed at the normal emission.pt_BR
