Impurities and their complexes, whether introduced deliberately or accidentally during fabrication dominate the properties of semiconductors devices. Determining the actual elemental and physical structure of a defect responsible for undesirable effects in devices can be remarkably difficult. A good example is the Boron-oxygen degradation mechanism in Silicon solar cells. This defect degrades...
Single-phase multi-principal element alloys, termed as high-entropy alloys (HEAs), are in focus of an intensive research now, both for fundamental understanding and technological applictions. A “sluggish” diffusion concept [1] helped to boost an interest from many diffusion groups and to improve our knowledge on diffusion in the multicomponent alloys. In the overview, the current...
Among the many point defect colour centers in diamond, which are currently being intensively investigated for their applications in processing of quantum information, a Mg-related center has recently attracted special attention [1-3]. It is assumed that the center consists of a single Mg atom with one vacancy attached to it (MgV), which can also be pictured as a Mg atom occupying a bond-center...
Diamond is a material with multiple promising color centers for quantum technologies. In this work, emission channeling (EC) measurements and ab initio calculations were performed to study Ca defects in this material. The present work forms part of a more systematic study into the properties of group II elements in diamond, with EC experiments performed for the $^{27}$Mg, $^{45}$Ca, and...
