TL;DR: In this article, the structure of the polar surfaces of ZnO was studied using ab initio calculations and surface x-ray diffraction and the experimental and theoretical relaxations were in good agreement.

Gold Schottky contacts on oxygen plasma-treated, n-type ZnO(0001̄)
TL;DR: In this article, the reverse bias current-voltage measurements of ∼100-μm-diameter gold Schottky contacts deposited on n-type ZnO(0001) wafers and those exposed for 30 min to a remote 20% O2/80% He plasma at 525±20 C and cooled either in vacuum from 425 °C or the unignited plasma gas have been determined.

Competing stabilization mechanism for the polar ZnO(0001)-Zn surface
TL;DR: In this article, density functional calculations for the (0001)-Zn surface of wurtzite ZnO are reported, and different stabilization mechanisms, such as metallization of the surface layer, adsorption of OH groups or O adatoms, the formation of Zn vacancies, and large scale triangular reconstructions are considered.

Stability of the polar surfaces of ZnO: A reinvestigation using He-atom scattering
TL;DR: In this article, a reinvestigation of the O-terminated, polar surface of zinc oxide, O-ZnO(0001\ifmmode\bar\else\textasciimacron\fi{}), using scattering of thermal energy He atoms reveals the presence of a reconstruction for the clean surface.

TL;DR: Combining several types of first-principles calculations with advanced molecular beam methods, this study is able to provide conclusive evidence that the polar O-terminated surface of ZnO is either reconstructed or hydrogen covered.
