Despite being the simplest element, hydrogen (H) exhibits complex behavior in materials
due to its unique ambipolar character. In particular, it is recognized as one of the most …

The rapid developments of computational quantum chemistry methods and supercomputing
facilities motivate the renewed interest in the analysis of the muon/electron interactions in …

Thin films and pn junctions for solar cells based on the absorber materials Cu (In, G a) Se 2
and Cu 2 ZnSnS 4 were investigated as a function of depth using implanted low energy …

In positive muon spin rotation and relaxation spectroscopy it is becoming customary to take
advantage of density functional theory (DFT) based computational methods to aid the …

We present a systematic study of isolated hydrogen in diverse forms of ZrO 2 (zirconia), both
undoped and stabilized in the cubic phase by additions of transition-metal oxides (Y 2 O 3 …

Muonium, a positive muon and an electron, is often used as an experimentally accessible
substitute for hydrogen in materials research. In semiconductors and insulators, a large …

The electronic structure of hydrogen impurity in Lu 2 O 3 was studied by first-principles
calculations and muonium spectroscopy. The computational scheme was based on two …

The incorporation of interstitial hydrogen in yttria was studied by means of ab initio
calculations based on density-functional theory (DFT) and muonium spin polarization …

Muon spin rotation has long been recognized as one of the few methods for experimentally
accessing the electronic state of dilute hydrogen (H) in semiconductors and dielectrics …

In muon-spin-rotation experiments, positive muons are implanted in the material and come
to rest in the unrelaxed host lattice. The formation of the final configuration requires a lattice …
