Phys. Rev. Materials 2, 051601(R) (2018) - Published 14 May, 2018

The abundant transparent semiconductor ZnO stands out for its numerous applications, notably due to its optoelectronic properties, which are also determined by electron density and dimensionality. This work reports the creation of a high-density two-dimensional electron system in ZnO by simply depositing a thin layer of pure aluminum in vacuum. The authors use angle-resolved photoemission to image the metallic subbands, which are a textbook case of a 2D Fermi liquid coupled to a Debye distribution of phonons. Furthermore, while doping mechanisms in ZnO have been a controversial issue, in the present work oxygen vacancies are shown to be essential.

Nucleation of ripplocations through atomistic modeling of surface nanoindentation in graphite

D. Freiberg, M. W. Barsoum, and G. J. Tucker

Phys. Rev. Materials 2, 053602 (2018) - Published 4 May, 2018

It has always been assumed that basal dislocations are the main deformation micromechanism operative when layered crystalline materials are loaded in compression. Recently, the authors showed that ripplocations, small ripples in the layers, and not basal dislocations are the operative mechanism. Herein, by modeling the indentation of graphite, using atomistic methods, the authors show that the ripplocation nucleation stresses are dependent on the strain gradients engendered by the different indenter radii modeled. Furthermore, they show how the rapid alignment of ripplocations, on adjacent layers, form oppositely oriented ripplocation boundaries that quickly propagate—wavelike—away from just below the indenter. This massive strain delocalization has never been previously reported in contact mechanics where it has always been assumed that the range of influence of an indenter was roughly the size of the indenter.

Structural and electronic properties of the alkali metal incommensurate phases

Gavin Woolman, Victor Naden Robinson, Miriam Marqués, Ingo Loa, Graeme J. Ackland, and Andreas Hermann

Phys. Rev. Materials 2, 053604 (2018) - Published 11 May, 2018

Alkali elements form extremely complicated structures under pressure, involving two interpenetrating, incommensurate lattices. The mechanism that stabilizes these structures is not known. In this work, the authors use density functional theory calculations to examine several possible options. After demonstrating that the calculations can capture quite subtle structural changes across the different elements, they show that in all cases the respective host structures combine two types of electride behavior: fully localized electron pairs and electrons partially localized along 1D wells. The guest atoms are seen to aid the structural formation by providing additional electronic charge and optimizing the overall packing density

Rutile ${IrO}_{2} / {TiO}_{2}$ superlattices: A hyperconnected analog to the Ruddelsden-Popper structure

Jason K. Kawasaki, David Baek, Hanjong Paik, Hari P. Nair, Lena F. Kourkoutis, Darrell G. Schlom, and Kyle M. Shen

Phys. Rev. Materials 2, 054206 (2018) - Published 23 May, 2018

Emergent properties in transition metal oxide superlattices are traditionally tuned as functions of stoichiometry, reduced dimensionality, and epitaxial strain. Here the authors introduce a new tuning parameter, the connectivity of the $M$ O $_{6}$ octahedra ( $M =$ transition metal), as a means to manipulate the electronic structure, symmetry, and competing ground states of oxide superlattices. They demonstrate this by the epitaxial growth of alternating layers of the high spin-orbit metal IrO $_{2}$ and the band insulator TiO $_{2}$ , both of which have the rutile structure.
