Fall 2018
Detection of biomolecules that are over- or under-expressed in diseases is an important field for early diagnosis, monitoring treatment, and improving patient prognosis. The main goal of my thesis is to utilize DNA nanotechnology combined with nanomaterials to provide sensitive and specific...

Spring 2016
This thesis explores the dynamics and sensing performance of silicon quantum dot (SiQD) ensembles coupled to the whispering gallery modes (WGMs) of spherical and cylindrical microcavities. The first project investigated the possibility of observing Purcell effects in an ensemble of QDs coupled to...

Spring 2015
This thesis focuses on the photoluminescence (PL) of free-standing silicon quan- tum dots (QDs). Large changes in the emission spectrum were found to occur when the QDs were exposed to different environments while undergoing short-wavelength laser irradiation, a phenomenon that was the main focus...

Noble Metal Free, Visible Light Driven Photocatalysis Using TiO2 Nanotube Arrays Sensitized by P‐Doped C3N4 Quantum Dots
Download2019-12-10
Bulk g‐C3N4 is an earth‐abundant, easily synthesizable, and exceptionally stable photocatalyst with an electronic bandgap of 2.7 eV. Herein, the concepts of P‐doping and size quantization are combined to synthesize highly fluorescent P‐doped carbon nitride quantum dots (CNPQDs) with a bandgap of...

Silicon (Si) based nanomaterials have the potential to revolutionize the microelectronics industry by introducing desirable nanoscale properties into electronic components without compromising the material composition. They have also been proposed as a greener alternative for many Group III-V and...

Fall 2017
This thesis will discuss the charge dynamics of dangling bonds (DBs) on the hydrogen terminated Si(100) surface under the effects of temperature and perturbations from local electric fields. The experimental methods are then extended towards DB chains. Electronic time resolved imaging techniques...
