Ionic and electronic transport in functional oxide materials is of great relevance for applications in the field of energy and data storage, e.g. solid oxide fuel cells (oxygen ion conductivity), oxygen permeation membranes (ambipolar diffusion of oxygen), or data storage materials (electronic and/or ionic conductivity). In this contribution our recent work on the influence of defect...

We have implanted 57Co (T½=271 d.) into ZnO single crystals, with the aim of elucidating some controversies in the Mössbauer literature on 57Fe impurities in ZnO. It is shown that some of the data obtained on 57Fe in ZnO has been misinterpreted. The results show that implantation >1E14/cm2 leads to incorporation of ~20% of the probe atoms into distorted substitutional sites, the reminder is...

The group-III nitrides (GaN, InN and AlN) are semiconductors with a large band gap which can be adjusted by combining the different nitrides into alloys. This provides them with the interesting electrical and optical properties used to create the light emitting diodes LED (from UV to red). For this the nitride semiconductors must be doped positively (p-type) and negatively (n-type), however...

We report on first results with ISOLDE radioisotopes collected in the frame of the LOI-121. We were able to demonstrate in vivo PET and SPECT imaging using 152Tb and 155Tb for the first time. Also in-vivo PET imaging with the long-lived in vivo generator 140Nd/140Pr was demonstrated, thus enabling longitudinal in vitro and in vivo PET monitoring of the biodistribution of antibodies over many...
