Journal ArticleDOI
Enhanced Spontaneous Emission by Quantum Boxes in a Monolithic Optical Microcavity
TL;DR: In this paper, a spontaneous emission rate enhancement by a factor of up to 5 was selectively observed for the QB's which are on resonance with one-cavity mode. But the effect of the random spatial and spectral distributions of the QBs was not considered.
Journal ArticleDOI
Segregation and ordering at surfaces of transition metal alloys: the tight-binding Ising model
TL;DR: In this paper, the authors derived an effective Ising Hamiltonian for segregation and ordering processes at transition metal alloy surfaces, which proved to be very close to the difference in surface tensions between pure constituents and a quadratic one involving effective pair interactions larger at the surface than in the bulk.
Journal ArticleDOI
Silicon Nanotweezers With Subnanometer Resolution for the Micromanipulation of Biomolecules
Christophe Yamahata,Dominique Collard,Bernard Legrand,T. Takekawa,Momoko Kumemura,Gen Hashiguchi,Hiroyuki Fujita +6 more
TL;DR: In this paper, the authors describe an electrostatically actuated silicon nanotweezers which are intended for the manipulation and characterization of filamentary molecules, and demonstrate their performance in static and dynamic manipulation on DNA molecules.
Journal ArticleDOI
Alloy surfaces: segregation, reconstruction and phase transitions
Guy Tréglia,Bernard Legrand,François Ducastelle,Andrés Saúl,C. Gallis,I. Meunier,Christine Mottet,A. Senhaji +7 more
TL;DR: In this paper, the authors consider surface segregation in alloys, i.e., concentration modulation in the surface selvedge at thermodynamical equilibrium, can be viewed as resulting from two kinds of competition or synergy.
Journal ArticleDOI
Structures of a Ag monolayer deposited on Cu(111), Cu(100), and Cu(110) substrates: An extended tight-binding quenched-molecular-dynamics study.
TL;DR: The atomic structure of a Ag monolayer deposited on the three low-index faces of a Cu substrate is determined by means of an extended tight-binding quenched-molecular-dynamics simulation.
