The refresh times of all dynamic charge storage devices, best
characterized by the generation lifetime at roan temperature and the
recombination lifetime at higher device operating temperatures
(T>70°C), strongly influence the efficient and successful operation
of dynamic charge storage devices such as DRAM's and CCD's. Both
recombination and generation lifetime...
The major goal of this research work was to develop better
electrical measurements for the evaluation of silicon material
quality.
The first approach investigated was the Zerbst generation
lifetime measurement technique. It was demonstrated that the
error in the estimation of the generation lifetime obtained with
this technique could be...
The surface tension kin'ti4tnd ste'dy state behavior exhibited by mixtures of selected
surfactants with a recombinant Factor VIII (rFVIII) were evaluated with automated
interfacial tensiometry. In particular, fresh solutions of rFVIII with different concentrations
of Tween 80, sodium dodecylsulfate (SDS), or dodecyltrimethylammonium bromide
(DTAB) were prepared and their surface tension...
In the first part of this dissertation, low frequency l/f or flicker noise in the frequency range of Hz to kHz has been identified and demonstrated to be described by temperature fluctuations in heat conduction in bipolar transistors operated at higher power densities. This noise phenomenon is not described by...
Solar photovoltaic is considered one among many new alternatives to satisfy
our demand for energy. Solar Cells have undergone changes in the last 50 years or so
since its invention in 1954. Solar power is beginning to challenge conventional
energy sources in terms of mainstream acceptance. Solar power along with...
