Atomically-resolved electronic structure of epitaxial graphene
(Georgia Institute of Technology, 2009-01)
Development of Porous Silicon Microfilters
(Georgia Institute of Technology, 2009-05-04)
This study develops a one-step anodization separation process (OSS) after examining two step and multi step liftoff procedures in which porous silicon (PS) films lift off from their substrates. This lift-off process provides ...
Twistor Theory, Then and Now
(Georgia Institute of Technology, 2009-03-25)
Twistor theory is now over 45 years old. In December 1963, I proposed the initial ideas of this scheme, based on complex-number geometry, which presents an alternative perspective to that of standard 4-dimensional space-time, ...
Aeons Before the Big Bang?
(Georgia Institute of Technology, 2009-03-24)
There is much impressive observational evidence, mainly from the cosmic microwave background (CMB), for an enormously hot and dense early stage of the universe referred to as the Big Bang. Observations of the CMB are now ...
Graphene nanoribbon array fabrication by oxygen gas plasma etching through sub-micrometer porous filters
(Georgia Institute of Technology, 2009-08-07)
We investigate a novel method of fabricating a network of graphene nanoribbon structures. The process is a sharp departure from conventional nanolithographic techniques in both method and amount of time required. Epitaxial ...
March of the SandBots
(Georgia Institute of Technology, 2009-04)
Goldman at Georgia Tech, Koditschek and Komsuoglu at the University of Pennsylvania, in Philadelphia, and other collaborators - are hoping that by studying the zebra-tailed lizard and a menagerie of other desert-dwelling ...
Sensitive dependence of the motion of a legged robot on granular media
(Georgia Institute of Technology, 2009-03-03)
Legged locomotion on flowing ground (e.g., granular media) is unlike locomotion on hard ground because feet experience both solid- and fluid-like forces during surface penetration. Recent bioinspired legged robots display ...
Nonlinear approach to electronic beam steering
(Georgia Institute of Technology, 2009-07-14)
Electric deflection measurements of sodium clusters in a molecular beam
(Georgia Institute of Technology, 2009-11-10)
Rotationally averaged polarizabilities and intrinsic electric dipole moments of sodium clusters are measured and reported. The experimental method is a molecular beam deflection. Our precision is the highest (<5%) and the ...
Theory of phase transitions in disordered crystal solids
(Georgia Institute of Technology, 2009-06-29)
Solid-state amorphization of a crystalline solid to an amorphous phase is extensively studied as a first order phase transition at low temperature for almost thirty years. In this dissertation, we report the recent progress ...
