TLDR
In this paper, the authors conduct a high-throughput computational search on thousands of binary and ternary oxides and identify several highly promising compounds displaying exceptionally low hole effective masses (up to an order of magnitude lower than state-of-the-art p-type transparent conducting oxides), as well as wide band gaps.Abstract:
The development of high-performance transparent conducting oxides is critical to many technologies from transparent electronics to solar cells. Whereas n-type transparent con- ducting oxides are present in many devices, their p-type counterparts are not largely com- mercialized, as they exhibit much lower carrier mobilities due to the large hole effective masses of most oxides. Here we conduct a high-throughput computational search on thousands of binary and ternary oxides and identify several highly promising compounds displaying exceptionally low hole effective masses (up to an order of magnitude lower than state-of-the-art p-type transparent conducting oxides), as well as wide band gaps. In addition to the discovery of specific compounds, the chemical rationalization of our findings opens new directions, beyond current Cu-based chemistries, for the design and development of future p-type transparent conducting oxides.read more

Categorization of surface polarity from a crystallographic approach
TL;DR: In this article, an efficient algorithm based on isometries is proposed to identify whether a slab with the given surface orientation would be intrinsically polar and if not, to obtain information on where to cleave the bulk crystal to obtain a stoichiometric nonpolar slab and whether reconstruction is necessary to generate a stoicometric slab that is not polar.

Stable hybrid organic–inorganic halide perovskites for photovoltaics from ab initio high-throughput calculations
TL;DR: In this article, the periodic table of elements for hybrid organic-inorganic halide perovskites, using high-throughput density-functional theory calculations, was used to identify the most promising candidates for further experimental and theoretical characterization.

Electronic structure and defect properties of B6O from hybrid functional and many-body perturbation theory calculations: A possible ambipolar transparent conductor
TL;DR: In this article, a combination of hybrid functional and many-body perturbation theory calculations was performed on the electronic structure and defect properties of B6O, and it was shown that the p-type doping is not prevented by intrinsic defects such as oxygen vacancies, which act exclusively as neutral defects rather than hole-killing donors.

Generalized Gradient Approximation Made Simple
TL;DR: A simple derivation of a simple GGA is presented, in which all parameters (other than those in LSD) are fundamental constants, and only general features of the detailed construction underlying the Perdew-Wang 1991 (PW91) GGA are invoked.

Projector augmented-wave method
TL;DR: An approach for electronic structure calculations is described that generalizes both the pseudopotential method and the linear augmented-plane-wave (LAPW) method in a natural way and can be used to treat first-row and transition-metal elements with affordable effort and provides access to the full wave function.

TL;DR: A detailed description and comparison of algorithms for performing ab-initio quantum-mechanical calculations using pseudopotentials and a plane-wave basis set is presented in this article. But this is not a comparison of our algorithm with the one presented in this paper.
