We intend to detail the muonium dynamics and investigate the interaction with charge carriers in n-type ZnSe. A doped ZnSe sample (resistivity=10^4 Ohm.cm, n=10^13 cm^-3) is...

Since 2009, perovskite solar cells (PSCs) have become a topic of immense interest in the research community, while performances of PSCs are in a position to challenge the...

Potassium tetracyanoquinodimenthane (KTCNQ) undergoes a spin-Peierls (SP) transition at 396K where a transformation from uniform to dimerised TCNQ- molecules in 1D columns...

In the current work, we study inorganic solid-state electrolytes for lithium-ion batteries. These materials, unlike the traditional liquid electrolytes, could lead to a...

We propose to use muons to probe the diffusion processes which occur within a battery anode during cycling in an all solid-state battery. Such solid-state battery configurations...

This is an in depth study of magnetic fluctuations and local field dynamics leading into the low temperature magnetic phase of Vanadium Oxide compounds (VO2, VO2:W and VO2:Ti)...

Here we propose to use muon spectroscopy to study the diffusion of sodium in hard carbon anode materials of various porosity for sodium ion batteries. Hard carbon is the most...

We propose a study to characterize diffusive motion of muonium, charge cycles and Mu0 states in vanadium dioxide (VO2) using zero and longitudinal field muon spin depolarization...

The reversible interconversion of protons and dihydrogen is an electrochemical process of fundamental importance to a hydrogen economy. The process requires catalysis to proceed...

In this proposal, we wish to study the origin of the multiferroic nature in Sr4Fe2(CO3)O6. In the magnetization data, antiferromagnetic (AFM) ordering appears at TN = 340 K and...

The first experiment we propose is a search for a shallow-donor signal for muonium in indium oxide. Its observation would test our assertion, based on our measurements of...

PffBT4T-2OD is one of the most recent and most successful low bandgap conjugated polymers used in organic photovoltaics - PffBT4T-2OD based OPV devices have power conversion...

Nearly all polymers form glasses and the glass transition at temperature Tg dominates many physical properties of polymers that are relevant for their applications. The most...

Since the discovery of the iron-pnictides superconductors most of the efforts has been devoted to the study of the fundamental questions concerning the coexistence of magnetism...

Solid state repolarisation measurements of [Fe2(µ-pdt)(CO)4(PMe3)2] (RB 1010177) showed a weak recovery at ca.15G, a strong recovery at ca.100G and what was thought to be a weak...

BiCoO3 is a perovskite type material recently prepared by high pressure-high temperature synthesis in Kyoto. It has a distorted acentric perovskite structure with order of high...

Carbon nanostructures presenting charge-transfer behavior (e.g. fullerene) can display high affinity to hydrogen and are promising materials for reversible hydrogen storage....

Continued investigation of magnetic fluctuations in the Mn-doiped chalcopyrite semiconductor ZnGeP2 is proposed using LF-MuSR depolarization rates. Due to ferromagnetism above...

The origin of the Invar effect, whereby certain ferromagnetic alloys exhibit near zero thermal expansion around room temperature is still not properly understood. Although the...

Skyrmions are chiral spin textures that exist in a variety of magnetic materials. These states are topologically non-trivial, which gives them stability expected to be useful...
