Abstract Details

2016, Master of Science, University of Akron, Electrical Engineering.
The main objective of this thesis is to study the ferroelectric behavior of thin film barium strontium titanate and multiferroic behavior of nanoporous polyvinylidene fluoride. The ferroelectric behavior of thin film barium strontium titanate is studied using an experimental set-up based on metal-insulator-metal capacitors and a new approach for microwave power detection is presented. Electric-field-induced, anharmonic dipolar resonances of room-temperature, barium strontium titanate thin films have been used to rectify and detect microwave signals with frequencies ranging from 2 GHz to 3GHz. The resonant frequency was shown to have strong dependence on film thickness with some amount of voltage-controlled tunability. Our experiments involved lock-in detection of a 100% amplitude modulated microwave signal with power levels ranging from -20 dBm to +10 dBm (the maximum power attainable from available instrumentation). An on-resonant sensitivity of 0.6 mV/mW was observed. This power detection sensitivity was shown to have built-in band-pass filtering corresponding to the resonant line shape. Because the thin films were produced using a relatively inexpensive solution deposition method, we believe that our observed phenomena could be exploited for the purpose of reducing the cost and increasing the availability of engineering applications that relies on microwave power detection. The multiferroic behavior of nanoporous polyvinylidene fluoride (PVDF) with metallic nanowires is studied on an interdigital capacitor. A simulated model for the interdigital capacitor to extract the material properties of multiferroic material (nanoporous PVDF with magnetic nanowires) is presented. The model is accurate and gave the closest results for three-finger and six-finger coplanar waveguide interdigital capacitors (CPWIDC) compared to CPWIDC’s with four and five fingers.
