Defects in diamond have great potential for use as quantum sensors and qubits. The negatively-charged nitrogen-vacancy (NV–) center in diamond is established as a leading platform in solid state quantum applications, with potential technologies in sensing, computation and communication enabled by its long spin-coherence time and optical spin polarization. However, NV’s poor photonic properties...
During 2017 we focused on investigating the lattice location of 27Mg as a detailed function of implantation temperature, implanted fluence, and fluence rate in different doping types of GaN: undoped GaN, as well as Si-doped n-type, Mg-doped p-type, and Mg-doped as grown.
The amphoteric nature of Mg, i.e. the simultaneous occupation of substitutional Ga and interstitial sites previously...
The unique method of 57Fe emission Mössbauer spectroscopy (eMS), as performed at the large-scale facility of ISOLDE at CERN, was employed to reveal, at the most atomic-scale, important aspects governing the amorphous-to-crystalline phase transition in GeTe thin films, of importance for phase change memory (PCM) applications. By following dilute implantation of 57Mn (T½ = 1.5 min) decaying to...
Within the Standard model, the CKM matrix is predicted to be unitary. Testing this unitarity is therefore important to put limits on Beyond Standard Model physics contributions. The dominant matrix element for this test, Vud, is traditionally obtained from the corrected ft-values of superallowed pure Fermi beta transitions [1]. Another sensitive way to address Vud is through measuring the...
$^{31}Ar$ isotope is one of the most exotic β-delayed particle precursors, near the proton drip-line, with high Q-value and low proton separation energy. Due to these two factors, many channels are opened and β-delayed protons are emitted in the decay of this nucleus (one-proton, two-proton and even three-proton emission) [1].
Taking advance of the ISOLDE Decay Station (IDS) [2], the decay...
