A study of three transition metal compounds and their applications
… with the charge-ordered (CO) insulator phase. High Pr doping will favor the CO order, leading a sharp FM to CO dominated phase transition around Pr concentration of 0.3 and above. Hydrostatic pressure favors FM metallic order without damaging the sample and can be tuned continuously. In this …

Compact Leaky Wave Antenna Using Ferroelectric Materials
… in this thesis is focused on implementation of material (like PZT) with high dielectric constant (k) in a rectangular waveguide leaky wave antenna. Due to the high dielectric constant of PZT ~ 1,900, the propagation wavelength in the waveguide can be dramatically shortened. This allows the leaky …

Alternative gate dielectrics and application in nanocrystal memory
… (Ge) nanocrystal memory structures, employing high dielectric constant (high-k) materials to replace the tunnel oxide and capping oxide (control oxide) layers, was investigated. It was found that faster charging rate and better charge retention performance could be obtained with a high-k tunnel …

Protein-mediated nanocrystal assembly for floating gate flash memory fabrication
… for novel device concept, architecture and new materials has never been so pressing as today. Flash memories, the driving force of semiconductor memory market in recent years, also face the same or maybe more severe challenges to meet the demands for high-density, low-cost, low-power, …

Design and optimization of ultrathin silicon field effect transistor's for sensitive, electronic-based detection of biological analytes
… structure, require the use of no labels, and are highly sensitive to the binding of molecules to their surfaces. This is due to the large surface area to volume ratio afforded to nanowires. Moreover, arrays of silicon nanowires have demonstrated multiplexed, label-free sensing of cancer markers …
