Amorphous multi-component metals as electrode materials

Creator:: Cowell, E. William
Abstract:: The objective of this thesis is to provide an initial demonstration of two-terminal and three-terminal electronic devices employing amorphous multi-component metallic film (AMMF) electrodes. Such a demonstration is successfully achieved in the fabrication of metal-insulator-metal (MIM) diode and hot electron transistor (HETs) structures employing ZrCuAlNi AMMF electrodes. The ultra-smooth surface...

A comparative study between sinusoidal and squarewave clocking for alleviating the jitter limitation in multi-gigaHertz ADCs

Creator:: Kesharwani, Divya
Abstract:: Various applications like wireless UWB communication, fast data acquisition systems and digital storage oscilloscopes needs ADCs with instantaneous input signal bandwidth from 0.1-40 GigaHertz range with 6-10 bits of resolution -- a challenging task and an impressive goal to achieve. Flash ADCs have been conventionally employed to achieve these goals...

Magnetically programmable surface acoustic wave devices for RFID applications

Creator:: Chin, Matthew
Abstract:: Magnetically programmable surface acoustic wave (MP SAW) devices were designed, fabricated and characterized in this thesis using integrated giant magnetoresistive (GMR) bits with interdigital reflectors. This provides a proof of concept of a novel storage element on radio frequency identification tags. Interdigital transducers (IDTs) on a piezoelectric substrate are used...

Integration of vapor-solid grown ZnO nanowires through dielectrophoresis

Creator:: Ng, Vi-Vie
Abstract:: Work on individually constructed devices has demonstrated that nanowires (NWs) offer great promise for applications such as sensing and optoelectronics. Despite this work, reliable large scale alignment and integration of these individual nanostructures into a lithographically defined process remains a challenge. Dielectrophoresis (DEP) is a promising alignment method in which...

Model development via delay extraction for the time-domain simulation of lossy transmission lines.

Creator:: Blevins, Chris
Abstract:: This thesis presents two new approaches for the broadband, time-domain modeling of lossy transmission lines. Each approach is based on an alternative derivation of delay extraction in order to separate the line's linear phase from its attenuation and dispersion. Augmentation networks represent the derived attenuation networks as rational function approximations....

Inertial control of a beamforming antenna array for use in cellular phones

Creator:: Schmidt, Patrick (Patrick Lane)
Abstract:: This research explores the viability and effectiveness of using an inertial navigation system (INS) to control a beamforming array of microstrip patch antennas with the aim of reducing users' exposure to electromagnetic radiation. The system reduces radiated power directed toward a cellular phone user to below 10% of the total...

Electrical characterization of thermally reduced graphite oxide

Creator:: Jewell, Ira
Abstract:: This thesis describes the transport properties observed in thermally treated graphite oxide (GO), which holds promise as an economical route to obtaining graphene. Graphene is a material consisting of a single atomic plane of carbon atoms and was first isolated as recently as 2004. Several isolation techniques have been investigated,...

Electrical recommendations and formulas for metal fill in radio-frequency integrated circuits

Creator:: Gaskill, Steven
Abstract:: With increasing transistor operating frequencies, interconnects and passive devices are becoming performance limiters in integrated circuit (IC) designs. To combat this, the interconnect layers above the active silicon are trending toward low-κ dielectrics and Cu metallization. The use of these new materials has popularized chemical mechanical polishing (CMP) to planarize...

Understanding the ultra-wideband channel within a computer chassis

Creator:: Redfield, Stephen J.
Abstract:: Recent developments in computing technology have generated a demand for more streamlined and effective test systems. By replacing traditional in-chassis wired interconnects with a broadcast wireless system, fault detection and error susceptibility will drastically improve, input/output capabilities will expand, and routing complexity will decrease. Ultra-wideband impulse radio's (UWB-IR) characteristic multipath-immunity...

Development of leadership and design skills among ECE juniors and graduate students

Creator:: Luo, Ding
Abstract:: Engineering students spend a significant amount of their undergraduate careers focused on technical theory and practice. This intensive student prepares them for their technical challenges in the future. This training is so intense that often the more 'soft skills' such as communication, leadership, design, and troubleshooting are left out or...
