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…
Magnetooptical properties of (Ga,Fe)N layers
J. Papierska, J. -G. Rousset, W. Pacuski +13
Magnetooptical properties of (Ga,Mn)N layers containing various concentrations of Fe-rich nanocrystals embedded in paramagnetic (Ga,Fe)N layers are reported. Previous studies of su…
Relation between exciton splittings, magnetic circular dichroism, and magnetization in wurtzite (Ga,Fe)N
J. -G. Rousset, J. Papierska, W. Pacuski +12
The question of the correlation between magnetization, band splittings, and magnetic circular dichroism (MCD) in the fundamental gap region of dilute magnetic semiconductors is exa…
Modification of emission properties of ZnO layers due to plasmonic near-field coupling to Ag nanoislands
Joanna Papierska, Bartłomiej S. Witkowski, Anastasiya Derkachova +7
A simple fabrication method of Ag nanoislands on ZnO films is presented. Continuous wave and time-resolved photoluminescence and transmission are employed to investigate modificati…
