Solid State Physics
- Ulrich Wahl (Universidade de Lisboa (PT))
ISOLDE has been a hub for the development of radioactive probe techniques and their application in solid state physics and other fields. In this talk, we review some recent highlights from the application of electron emission channeling and perturbed angular correlation spectroscopy to research on functional quantum materials: from well-established research activities on doping of...
Multiferroic Rashba semiconductors (MUFERS) are novel functional materials based on the coupling between ferromagnetism, ferroelectricity and Rashba-Zeeman effects [1]. Ge$_{1-x}$Mn$_x$Te, the model MUFERS, inherits the robust ferroelectricity and giant Rashba splitting of $\alpha$-GeTe, undergoing a ferroelectric phase transition at $T_C^{FE}$. Below the transition temperature, the cubic...
Magneto-electric multiferroics form an attractive class of materials, not only for the diversity of exciting fundamental phenomena they present but also by the potential technological applications foreseen. Among them are energy efficient memory devices, multiple state memories, as well highly sensible electrical-magnetic field sensors. Although the research in this area has increased...
Currently, intensive research in group III nitrides is focussed on improving the performance of commercial devices. This includes their heterostructures and/or alloys with other group III elements. Amongst the latter are ternary semiconductors such as Al$_{x}$Ga$_{1-x}$N, which are expected to give rise to unexpected photonic and magnetic functionalities when doped with magnetic ion species....
Titania TiO2 is a promising material candidate for batteries, water splitting and water purification. Its photocatalytical and Li-storage capabilities very much depend on the defect structure in the used titania. Hydrogenation and N-doping have proven to improve this defect structure in such a way that the mentioned properties are drastically improved [1–3].
With the help of nuclear solid...
