Polyallylamine films, deposited on Si wafers by radio frequency (RF) pulsed plasma polymerization (PPP), were employed as insulating layers of metalinsulator-semiconductor (MIS) capacitors. The insulating polymer films were deposited at plasma reactor temperatures of 25°C and 100°C. Multiple frequency capacitance-voltage (C-V) measurements indicated that an in-situ heat treatment during film de...
Polymer-assisted deposition method has been used to fabricate self-assembled epitaxial La0.67Ca0.33MnO3:NiO and La0.67Ca0.33MnO3:Co3O4 films on LaAlO3 substrates. Compared to pulsed-laser deposition method, polymer-assisted deposition provides a simpler and lower-cost approach to self-assembled composite films with enhanced low-field magnetoresistance effect. After the addition of NiO or Co3O4,...
In this study, a high-sensitivity and low-hysteresis porous metal-insulator-metal-type capacitive humidity sensor is investigated using a functional polymer mixed with TiO2 microparticles. The humidity sensor consists of an optimally designed porous top electrode, a functional polymer humidity sensitive layer, a bottom electrode, and a glass substrate. The porous top electrode is designed to in...
As minimum device dimensions continue to shrink and on-chip device densities grow, signal distortion caused by capacitive coupling and crosstalk between the interconnections will increase. The current insulator material for on-chip applications is silicon dioxide (k= 3.9 4.2). The next generations of microchips require interlayer dielectrics with dielectric constants below 2.2 [I, 21. Although ...

We describe a simple model for treating the frequency-dependent conductivity σe(ω) and dielectric function Re e(ω) of a quasi-one-dimensional conducting polymer. The polymer is modelled as a composite medium consisting of spherical regions of ordered polymer, randomly distributed in a much more disordered polymer host. Within each spherical region, the polymer chains are highly oriented, but th...
