Alternating-current thin-film electroluminescent device optical excitation experiments

Creator:: Cleary, Bradford A.
Abstract:: This thesis investigates two methods of optical excitation of alternating-current thin-film electroluminescent (ACTFEL) devices. The two experimental methods investigated in this thesis are the photo-induced charge (PIQ) and luminescence (PIL), and the subthreshold-voltage induced transferred charge (VIQ) techniques. PIQ/PIL experiments utilize an above-bandgap laser pulse to investigate the transport properties...

From electrophoresis to dielectrophoresis: designing, fabricating, and evaluating an electroformed ratchet type microfluidic dielectrophoresis device

Creator:: Gonzalez, Carlos F.
Abstract:: Dielectrophoresis (DEP) is a separation method in which a non-uniform electric field is used to induce a dipole moment in a suspended particle. If the polarization of the particle is greater than that of the suspending medium, the particle will move towards the region of higher field strength (positive DEP);...

Active matrix electroluminescent device power considerations

Creator:: Beck, Douglas
Abstract:: An active-matrix electroluminescent (AMEL) design tool has been developed for the simulation of AMEL display devices. The AMEL design tool is a software package that simulates AMEL device operation using a lumped parameter circuit model. The lumped parameter circuit model is developed primarily to address AMEL power dissipation issues. The...

Design of a microstructured liquid-liquid separator utilizing a capillary pressure gradient

Creator:: Zoebelein, Conor M.
Abstract:: Continuous liquid-liquid two-phase separation is needed in microfluidic devices. Due to the small characteristic lengths of microreactors, phenomena such as mass transport via molecular diffusion occur within seconds. Typically, discrete slugs of an extract are created within microchannels for high specific interfacial area to achieve intensified mass transfer. A challenge...

Characterization of a diffusion soldering process for micro-technology-based energy and chemical systems manufacturing

Creator:: Gabriel, Michael A.
Abstract:: Several 316 stainless steel meso-scopic devices were made using a diffusion soldering process. Tensile strength and pressure drop of the devices were measured and metallurgical examinations were made of the joints. Continuous bonds were observed in the sample cross-section specimens. Strengths of the diffusion soldered joints were up to 56%...

A channelized digital receiver design for UWB sytems in a multipath indoor environment

Creator:: Chang, Yuhao
Abstract:: This thesis presents a channelized digital receiver design for UWB sytems in a multipath indoor environment. The UWB technology has been used for commercial and military purposes due to a number of advantages such as low-power consumption, noise-like and carrier free. The energy of UWB signal is spread over a...
