Light-matter interactions of two-dimensional materials and the coupled nanostructures
… interactions. This thesis project uses spectroscopy techniques and focuses on the study of the light-matter interaction in 2D materials, as well as their coupling with other nanostructures, which are essential in achieving useful optoeletronic applications with 2D materials. First, the …

CHARACTERIZATION OF CRYSTALLINE PIGMENTS WITH LOW-FREQUENCY VIBRATIONAL SPECTROSCOPY AND SOLID-STATE DENSITY FUNCTIONAL THEORY
… broader availability of terahertz time-domain spectroscopy (THz-TDS) and low-frequency Raman spectroscopy (LFRS). In this work, the capabilities of THz-TDS and LFRS for identification and characterization of historic and modern pigments were evaluated. These experimental studies were supported …

Exploring excitations and vibrations in semiconductor nanocrystals through fluorescence and Raman spectroscopy
… as a function of emission wavelength, and low-frequency Raman spectroscopy to measure acoustic phonons in nanocrystal solids. These two chapters serve as an introduction to the ideas and methods used throughout the thesis. In Chapter 3, Förster theory is used in conduction with spectrally- …

Computational Methodologies for the Simulation and Analysis of Low-frequency Vibrations in Molecular Crystals
… of the simulations to experimentally measured low-frequency (sub-200 cm-1) vibrational spectra. As this region is dominated by weak intermolecular forces and shallow potential energy surfaces, even slight miscalculations in the solid-state packing arrangements can become readily apparent. In …

Nanoscale Origins of Thermal Transport Phenomena for Hybrid Layered Perovskites
… foundation and experimental construction of a frequency domain thermoreflectance technique to effectively measure the cross-plane thermal conductivity of 2D LHPs. This technique is then utilized to perform the first measurement of the thermal conductivity of 2D LHPs. This experimental study …

Crystallisation and chain conformation of long chain n-alkanes.
… more complex systems. With this aim, vibrational spectroscopy has been extensively used. This technique, sensitive to molecular details, is the only one able to both identify and quantify conformational disorder present in paraffinic systems. To achieve this, methyl deformations have been widely …
