Anomalous behavior of native point defects in C2-ordered antiferromagnet $α$-MnO$_2$

$α$-MnO$_2$ is an emerging material for electronic, optoelectronic, and energy applications, owing to its structural flexibility and defect-driven functionality.

$α$-MnO$_2$ is an emerging material for electronic, optoelectronic, and energy applications, owing to its structural flexibility and defect-driven functionality. During synthesis of $α$-MnO$_2$, native oxygen vacancies readily form and are typically compensated by foreign…
