RF-mSR study of high-Ge Si1-xGex alloys
Single crystal, bulk Si1-xGex alloys are available across the alloy composition range, and provide opportunity for study of alloy properties in transition between the two... -
Towards a validated standard method for performing DFT calculations of muoniu...
In this proposal we want to address the issue of the identification of the different muonium adducts that are possible in Alq3 without any crystallographic constraints, and... -
Muonium Defect Levels in 4H Silicon Carbide
We propose to obtain the temperature dependence of the diamagnetic spin-precession amplitudes up to 1100 K for the three electrical types of 4H-SiC in order to extract the Mu... -
Thermal ionization of bond-centred muonium in diamond
Our previous LF-µSR measurements in natural type Ia single crystal diamond showed some evidence of the ionization of bond-centred muonium (MuBC) from around 1000K. This was... -
Electron polarisation of deep muonium states
Following recent experiments in which the shallow donor muon states in semiconductors are found to have significant electron polarisation at low temperatures and high fields, we... -
Probing the carrier-induced donor-to-acceptor transition of muonium in indium...
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... -
RF MuSR in the gas phase: The Search for a Radical State (RB920227)
The main spectroscopic technique for studying radicals in solids and liquids, ESR, cannot usually be used to study radicals of more than 3-5 atoms in the gas phase due to strong... -
Donor muonium state in rutile titanium dioxide
Rutile titanium dioxide is one of the most relevant oxide materials, where the impurity physics of hydrogen has recently been devoted much attention. Existing ab-initio... -
RF MuSR in the gas phase: the Search for a Radical State
The main spectroscopic technique for studying radicals in solids and liquids, ESR, cannot usually be used to study radicals of more than 3-5 atoms in the gas phase due to strong... -
RF-muSR in the gas phase: the muoniated ethyl radical
Radio-frequency muon spin resonance is an exceptional technique for studying free radicals, but it has not been applied to study radicals in the gas phase. In a previous... -
characterisation of muonium in functionalized acenes
We wish to measure the high field ALCs of a series of related functionalised acenes, to understand the role of the ligands on the electron spin relaxation, which is of... -
Temperature and environment dependence of the isotope effect in muonated radi...
We plan to measure the hyperfine constants for both the muon and the equivalent hydrogen atom in a small muonated radical using time-differential ALC. We will follow this as a...
