First Principles Investigations of Solid-Solid Interfaces in Lithium Battery Materials
… methods to model electrode/electrolyte interfaces for inorganic solid electrolyte materials, especially those related to Li$_3$PS$_4$. I develop a general scheme based on the interface energy for analyzing interfaces between crystalline solids, quantitatively including the effects of …

Study of phonon transmission through solid-solid interfaces and superlattices by phonon imaging
… pulses (phonons) through crystals and across solid-solid interfaces. The phonon imaging technique has been used to examine the angular and temporal dependence of the phonon-flux intensity in several systems, listed below. 1. Phonon focusing in cubic crystals. The nature of the intensity …

Defect engineering of polycrystalline titanium dioxide synthesized by atomic layer deposition
… the degree of fixed charge buildup at buried solid-solid interfaces in metal oxide thin film structures. Lastly, since the method of in-situ doping during ALD is unique in its ability to allow for decoupling of microstructure, defect composition, and doping level, the suitability of Mn-TiO2 …

Nonlinear Optical Spectroscopy of Gallium Arsenide Interfaces
The physics of buried solid/solid interfaces is interesting for both fundamental and technological reasons. In this thesis, second-order nonlinear optical spectroscopy was used to probe the electronic structure of GaAs based interfaces in the near infrared. Second-order nonlinear optical …

Characterisation of the effective thermal conductivity in the near wall region of a packed pebble bed
… adjusting the contact resistance values at the solid-solid interfaces of the pebble-pebble and pebble-wall contact points in the packed bed. Results were obtained by applying the developed methodology and separating the conduction and radiation components of the effective thermal conductivity. …

Nanoscale thermal transport through solid-solid and solid-liquid interfaces
… investigation of heat transport through solid- solid and solid-liquid interfaces. Heat transport is a process initiated by the presence of a thermal gradient. All interfaces offer resistance to heat flow in the form of temperature drop at the interface. In micro and nano scale devices, …

Heat transport by phonons in crystalline materials and nanostructures
… materials and nanostructures, and across solid-solid interfaces. Particularly, this dissertation emphasizes advancing understanding of the mean-free-paths (i.e., the distance phonons propagate without being scattered) of acoustic phonons, which are the dominant heat carriers in most …

Battery interfaces in the face of machine learning and artificial intelligence
… that can lower or eliminate such risks. Solid-state batteries hold promise as the next generation of batteries, using solid electrolytes in place of liquid electrolytes, which can bring improvements in not just safety but also battery performance. However, before practical solid-state …
