Defect Generation and Evolution in Irradiated Epitaxial Films and Heterostructures of Fe3O4 and Cr2O3

open access: yesAdvanced Materials Interfaces, EarlyView.
The functionality of nuclear structural materials, sensors, and microelectronics in radiation environments relies on understanding defect generation and evolution processes in oxide layers. The initial radiation response of Fe3O4 epitaxial thin films is characterized by the formation of large vacancy clusters, but these defects do not lead to lattice ...

Atomic Layer Deposition of ZnO Coating on Biodegradable Fe‐Based Alloys

open access: yesAdvanced Materials Interfaces, EarlyView.
A biodegradable Fe69Mn30C1 alloy is coated with ZnO using atomic layer deposition at 100 °C. Coating thickness impacts surface roughness, wettability, and in vitro degradation while maintaining hydrophilicity. The ZnO coating exhibits significant antibacterial activity against Staphylococcus aureus, achieving an inhibitory rate of up to 99.2%, and can ...

Investigating Dopant Effects in ZnO as an Electron Transport Layer for Enhanced Efficiency in Organic Photovoltaics

open access: yesAdvanced Materials Interfaces, EarlyView.
By doping the elements with different numbers of valence electrons (Al3+ and Sn4+ ions) into the ZnO matrix, device conversion efficiencies of 8.69% and 9.21%, respectively, are achieved. The ultrafast time‐resolved studies show that the elevated carrier concentration in Sn‐doped ZnO, in comparison with Al‐doped ZnO and un‐doped ZnO, plays a ...
