Deposition - mode ice nucleation reexamined at temperatures below 200

The environmental chamber of a molecular beam apparatus is used to study deposition nucleation of ice on graphite, alcohols and acetic and nitric acids at temperatures between 155 and 200 K. The critical supersaturations necessary to spontaneously nucleate water ice on six different substrate materials are observed to occur at higher supersaturations than are theoretically predicted. This contr...

Silicon epitaxy below 200°C: Towards thin crystalline solar cells

Low temperature plasma processes provide a toolbox for etching, texturing and deposition of a wide range of materials. Here we present a bottom up approach to grow epitaxial crystalline silicon films (epi-Si) by standard RFPECVD at temperatures below 200°C. Booth structural and electronic properties of the epitaxial layers are investigated. Proof of high crystalline quality is deduced from spec...

RAPIDITY IN √ s NN = 200 GeV Au + Au COLLISIONS Eric

Title of dissertation: ELLIPTIC FLOW AT FORWARD RAPIDITY IN √ sNN = 200 GeV Au+Au COLLISIONS Eric Michael Richardson, Doctor of Philosophy, 2012 Dissertation directed by: Professor Alice C. Mignerey Department of Chemistry and Biochemistry Forward rapidity elliptic flow (v2) of both unidentified charged hadrons and decay muons has been measured from √ sNN = 200 GeV Au+Au collisions as a functio...
