Volume 3: Structures, Safety, and Reliability.
Condition monitoring technique has been widely applied in Maritime to ensure safe operation and minimise unscheduled downtime. However, in practice, ship operators need to assure that a failure mode is indeed monitored by the sensor intended for it,

We discuss potential assurance frameworks for autonomous navigation systems in the maritime industry, with emphasis on testing and verification of the system’s perception performance and capacities. Ongoing research in this field has revealed profo

A significant conduction band offset appearing in n-ZnO/p-Si heterojunction solar cells is recognized as a serious roadblock to obtain high efficiency solar cells. By alloying with Mg, the conduction band in Zn1–xMgxO can be raised above that of Si

Li and H are important electrically active impurities in ZnO and this work presents a detailed experimental and computational study of the behavior of H and Li in ZnO and their effect on its defect structure. We employ AC conductivity measurements as

Fourier-transform infrared spectroscopy (FTIR) and secondary-ion mass spectrometry (SIMS) have been employed to investigate the relation between the Li concentration and the strength of the 3577 cm−1 absorption line in five as-grown hydrothermal Zn

Sublattice localization of impurities in compound semiconductors, e.g., ZnO, determines their electronic and optical action. Despite that the impurity position may be envisaged based on charge considerations, the actual localization is often unknown,

Diffusion of Li into ZnO from an “infinite” surface source under oxygen-rich conditions is studied using secondary ion mass spectrometry. The Li concentration-versus-depth profiles exhibit a distinct and sharp drop, which evolves in position with

We used depth-resolved cathodoluminescence spectroscopy (DRCLS) to describe the strong dependence of Li acceptor formation on thermal treatment in Li-doped ZnO. Within a 500-600 °C annealing temperature range, subsequent quenching ZnO leaves Li as i
