Metallic Solids

Metallic Solids

Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Computational Chemistry

Background:

Point defects and their atomic/electronic structures are crucial for material properties like corrosion resistance and optoelectronic device performance.
Complex energy landscapes with metastable defect configurations pose challenges for accurate first-principles modeling.

Purpose of the Study:

To reevaluate native point defect geometries in α-Al2O3 using various computational sampling methods.
To identify novel defect configurations and assess the effectiveness of different geometry sampling techniques.

Main Methods:

Density Functional Theory (DFT) calculations were employed to study point defects in α-Al2O3.
Three distinct methods for sampling candidate geometries were compared: atomic displacement, Voronoi decomposition initialization, and Bayesian optimization.

Main Results:

Symmetry-breaking distortions were observed for oxygen vacancies in certain charge states.
Several distinct oxygen split-interstitial geometries were identified, potentially resolving literature discrepancies.
A previously unreported trigonal geometry for aluminum interstitials was discovered.

Conclusions:

The identified novel defect configurations can significantly impact understanding of defect migration in protective aluminum-oxide scales.
The Voronoi scheme demonstrated superior effectiveness in sampling interstitial sites, consistently finding the lowest-energy geometries.
Defect geometry strongly influences defect level positions within the band gap, emphasizing the need for thorough ground-state geometry searches.
