Pore Characterization of Ultralow-k Dielectric Thin Films Using Positronium Annihilation Spectroscopy.
(2008)
In this thesis, a series of nanoporous ultralow dielectric constant (ULK) thin films fabricated using spin-coating and sacrificial pore generators (degradable porogens embedded in a host matrix) were studied as a function ...
Structural and Dynamical Properties of Complex Networks.
(2009)
Recent years have witnessed a substantial amount of interest within the physics community
in the properties of networks. Techniques from statistical physics coupled with the widespread availability of computing resources ...
Components for Monolithic Fiber Chirped Pulse Amplication Laser Systems.
(2009)
The first portion of this work develops techniques for generating femtosecond-pulses
from conventional fabry-perot laser diodes using nonlinear-spectral-broadening techniques
in Yb-doped positive dispersion fiber ampliers. ...
Ultrafast Dynamics of Photoexcited Bismuth Films.
(2010)
The carrier and lattice relaxation processes following photoexcitation in solids
occur over time-scales ranging from femtoseconds to nanoseconds. The eventual
conversion of the light to lattice heating involves carrier-carrier, ...
Measurement of Z --> cc Transverse Momentum Distribution in Proton-proton Collisions at s = 7 TeV in the ATLAS Detector.
(2011)
The normalized distribution of Z->ee transverse momentum spectrum is measured in proton-proton collisions at center-of-mass energy of 7 TeV with the ATLAS detector. The results are based on a dataset corresponding to an ...
A Generalized Theory of DNA Loop Formation: Considering the Effects of Binding Topology and Sequence-Dependent Curvature.
(2010)
We have developed a semi-analytic method for calculating the Stockmayer Jacobson J-factor for protein mediated DNA loop formation. Formation of DNA loops on the order of a few persistence lengths are key to understanding ...
Off-Grid Electricity Access and its Impact on Micro-Enterprises: Evidence from Rural Uganda.
(2010)
The history of development shows convincingly that no country has substantially reduced poverty without massively increasing the use of electricity. The development of micro-enterprises in rural areas of Uganda is linked ...
Electron Transport in Hall Thrusters
(2012)
Despite high technological maturity and a long flight heritage, computer models of Hall thrusters remain dependent on empirical inputs and a large part of thruster development to date has been heavily experimental in nature. ...
Measurement of The W Boson Production Cross Section and Search for the W' in The Muon Channel from pp Collisions at sqrt(s) = 7 TeV with the ATLAS Detector at the LHC
(2012)
This thesis reports the first measurement of the weak gauge boson W^{+-} production cross section in proton-proton collisions at center-of-mass energy of 7 TeV at the Large Hadron Collider with the ATLAS experiment. Data ...
Ultrafast Optical Studies of Phonon Polaritons, Squeezed Modes and High Frequency Diamagnetism in Metamaterials.
(2012)
The coupling of the electromagnetic field with polar lattice vibrations of a solid, which
gives rise to what is traditionally known as phonon polaritons, is investigated both through
spontaneous and stimulated Raman ...
