Metastability of Mn $^{3 +}$ in ZnO driven by strong $d$ (Mn) intrashell Coulomb repulsion: experiment and theory

A. Ciechan, H. Przybylińska, P. Bogusławski +5

Depopulation of the Mn $^{2 +}$ state in ZnO:Mn upon illumination, monitored by quenching of the Mn $^{2 +}$ EPR signal intensity, was observed at temperatures below 80~K. Mn $^{2 +}$ ph…

Fe dopant in ZnO: 2+ vs 3+ valency and ion-carrier s,p-d exchange interaction

J. Papierska, A. Ciechan, P. Bogusławski +16

Dopants of transition metal ions in II-VI semiconductors exhibit native 2+ valency. Despite this, 3+ or mixed 3+/2+ valency of iron ions in ZnO was reported previously. Several con…
