Fabrication of planar interdigitated electrodes for dielectric spectroscopy of thin filmsshenouda, mina 17 September 2014 (has links)
The dielectric properties of polymeric thin films (100-200 nm) are hard to
measure with the standard approaches as the samples aren't free standing necessitating
a supporting substrate. Consequently, a planar interdigitated sample holder
has been designed to hold the thin film where the polymeric capacitance was derived
from the passing fringing fields.
The electrodes were fabricated by creating 120 nm trenches in a SiO2/Si wafer; 20
nm Cr was deposited as an adhesion layer prior to the deposition of Cu by thermal
evaporation. The electrical measurements were implemented using HP 4294A and a
probe station.
Devices of 20 to 70 fingers were measured and the results were compared to the
analytical and finite element simulation. At 10 KHz, the total measured capacitance
of a 20-finger device was about 8 pF with 3 % represented the polymeric
contribution. The measurements differed from the calculations or finite modeling
results by about 12%.

Nanosecond pulse electroporation of biological cells: The effect of membrane dielectric relaxationSalimi, Elham 07 April 2011 (has links)
Nanosecond pulse electroporation of biological cells is gaining significant interest due to its ability to influence intracellular structures. In nanosecond pulse electroporation of biological cells nanosecond duration pulses with high frequency spectral content are applied to the cell. In this research we show that accurate modeling of the nanosecond pulse electroporation process requires considering the effect of the membrane dielectric relaxation on the electric potential across the membrane. We describe the dielectric relaxation of the membrane as dispersion in the time-domain and incorporate it into the nonlinear asymptotic model of electroporation. Our nonlinear dispersive model of a biological cell is solved using finite element method in 3-D space enabling arbitrary cell structures and internal organelles to be modeled. The simulation results demonstrate two essential differences between dispersive and non-dispersive membrane models: the process of electroporation occurs faster when the membrane dispersion is considered, and the minimum required electric field to electroporate the cell is significantly reduced for the dispersive model.
