Composition and strain in thin Si1-xGex virtual substrates measured by micro-Raman spectroscopy and X-ray diffraction
(2011)Micro-Raman spectroscopy was employed for the determination of the germanium content, x and strain, , in ultrathin SiGe virtual substrates grown directly on Si by molecular beam epitaxy. The growth of highly relaxed ... -
Kinetics of the barotropic ripple (P beta')/lamellar liquid crystal (L alpha) phase transition in fully hydrated dimyristoylphosphatidylcholine (DMPC) monitored by time-resolved x-ray diffraction.
(1991)We present here the first study of the use of a pressure-jump to induce the ripple (P,.)/lamellar liquid crystal (Lj phase transition in fully hydrated 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC). The transition ... -
Kinetics of the lamellar and hexagonal phase transitions in phosphatidylethanolamine. Time-resolved x-ray diffraction study using a microwave-induced temperature jump.
(1990)The kinetics of the thermotropic lamellar gel (L)/lamellar liquid crystal (La) and La/inverted hexagonal (H,,) phase transitions in fully hydrated dihexadecylphosphatidylethanolamine (DHPE) have been studied. Measurements ... -
A temperature gradient method for lipid phase diagram construction using time-resolved x-ray diffraction.
(1987)A method that enables temperature-composition phase diagram construction at unprecedented rates is described and evaluated. The method involves establishing a known temperature gradient along the length of a metal rod. ...
