Continuum and crystal strain gradient plasticity with energetic and dissipative length scales
… between two materials (e.g. grain boundary in crystals) into the formulation. The developed grain boundary flow rule accounts for the energy storage at the grain boundary due to the dislocation pile up as well as energy dissipation caused by the dislocation transfer through the grain boundary. …

Strain at surface and interface steps
… plane orientation allows for the imaging of crystal strain. In this thesis, I will present a unique method for quantitatively measuring crystal strain using TEM. This method relies on the quantitative comparison of experimental and simulated dark field images. Employing this technique has …

Water adsorption, microstructure, and volume change behavior of clay minerals and soil
Swelling attributable to intracrystalline water adsorption by montmorillonite (MT) and vermiculite (VR) saturated with cations which limit interlayer expansion were calculated as the product of one-half the change in interlayer spacing determined by x-ray diffraction and the difference between …

The tin-vacancy centre in diamond: a coherent spin-photon interface for quantum network nodes
… we introduce a new platform: deterministically strained tin-vacancy centres in a thin diamond membrane. The crystal strain allows microwave control of the spin state with a gate fidelity of 99.36(9) % at aligned magnetic fields with highly spin-selective optical transitions. Dynamical decoupling …

Survival of Brown Colour in Diamond During Storage in the Subcontinental Lithospheric Mantle
… storage in the graphite stability field. Crystal strain is preserved upon loss of brown colour during HPHT treatment. Inhomogeneous crystal strain was measured in 18 natural diamonds using micro-X-ray diffraction (μXRD) χ-dimension peak widths. There is a correlation between strain and …

Transport of free excitons and electron-hole droplets in silicon and germanium
… of moving EHD macroscopic distances in ultrapure crystals of silicon and germanium. Both the FE and the EHD shed momentum acquired from external forces by interaction with thermal phonons. This work places on a quantitative basis the rates at which these species lose momentum as a function of both …

Quantum magnetic imaging for DNA biophysical measurements
… microscopic inho- mogeneities due to diamond crystal strain were found to limit magnetic sensitivity and magnetic particle imaging frame rate. A novel quantum protocol was developed which ex- ploits the symmetry of the NV defect ground state structure to mitigate the contribution of …
