Electron-reflector strategy for CdTe thin-film solar cells
… layer. Thin CdTe cells can also benefit from the optical reflection at the back surface. To investigate the possibility of still higher efficiency, both electron and optical reflection were numerically applied to the CdTe record-cell baseline model. However, there is little improvement for CdTe …

Nanostructured Devices for Ultrasensitive and High Throughput Vibrational Spectroscopic Imaging
… particle probes are proposed. Their optical tunability with structure is discussed in detail and preliminary fabrication and validation are presented. Next, design and fabrication of a new class of filters for narrow-band optical reflection in mid-infrared spectral regions using …

Leveraging free carriers effects for infrared photonic structures and devices
… of ‘moth-eye’ structure and an extraordinary optical transmission grating. Therefore it has the capability to provide a uniform electrical distribution while simultaneously reducing the optical reflection loss. It can be applied to the active optoelectronic devices which require both optical …

The optical properties of bismuth nanowires
The optical absorption of bismuth nanowires in the energy (wavenumber) range of 600 - 4000cm-1 is studied. Optical reflection and transmission spectra reveal that bismuth nanowires have a large and intense absorption peak as well as several smaller absorption peaks which are not measured in bulk …

Stability of Beams, Plates and Membranes due to Subsonic Aerodynamic Flows and Solar Radiation Pressure
… lattice model for subsonic fluid flows or an optical reflection model for solar radiation forces. Combinations of these theoretical models are used to analyze the dynamics and stability of aeroelastic and solarelastic systems. The dissertation contains aeroelastic analysis of a cantilevered …

Tunable organization of cellulose nanocrystals for controlled thermal and optical response
… control and fine tuning of thermal and optical properties based on a proper understanding of their individual behavior and interactions at different length scales. In the present work, we attempt to provide an integral description of the influence of single crystals in the thermal and …

Properties and device applications of silicon and silicon-germanium nanostructures with different dimensions
… complete understanding of their structural, optical, electrical and thermal properties. This study explores these properties in two-dimensional (2D) Si/Si:B delta-doped multilayers, 2D Si/Si_{1-x}Ge_x planar multilayers, three-dimensional (3D) Si/Si_{1-x}Ge_x cluster multilayers, …

Probing the atmospheres of transiting exoplanets using ground-based multi-object spectroscopy
… observations of WASP-103b reveal a featureless optical spectrum and result in a detection of H2O when combined with GMOS, WFC3 and Spitzer data. The most likely explanation for this featureless spectrum may simply be a combination of low signal-to-noise and the inherently small atmospheric scale …

MoS2 on Gold: achieving extremely high exfoliation yield and optical contrast for Van der Waals monolayers
… work was carried out to improve the yield and optical contrast of exfoliated two-dimensional (2D) Van der Waals (VdWs) materials. Molybdenum disulphide (MoS2) on gold (Au) is investigated in detail as it provides an extremely large exfoliation yield and a high optical contrast. These techniques …
