Absorption enhancement in photonic crystal thin films by pseudo disordered perturbations

The effects resulting from the introduction of a controlled perturbation in a single pattern membrane on its absorption are first studied and then analyzed on the basis of band folding considerations. The interest of this approach for photovoltaic applications is finally demonstrated by overcoming the integrated absorption of an optimized single pattern membrane through the introduction of a proper pseudo disordered perturbation.Comment: MRS Fall Meeting 2013, Boston : United States (2013

Intrinsic Friction of Monolayers Adsorbed on Solid Surfaces

We overview recent results on intrinsic frictional properties of adsorbed monolayers, composed of mobile hard-core particles undergoing continuous exchanges with a vapor phase. In terms of a dynamical master equation approach we determine the velocity of a biased impure molecule - the tracer particle (TP), constrained to move inside the adsorbed monolayer probing its frictional properties, define the frictional forces exerted by the monolayer on the TP, as well as the particles density distribution in the monolayer.Comment: 12 pages, 5 figures, talk at the MRS Fall 2003 Meeting, Boston, December 1-5, 200

1987 Fall Field Day

The weather was bright and clear for the 75 people who attended some part of the 1987 Fall Field Day at the 4-H Camp at Halsey National Forest 3 and 4 October. It was nice to have Mrs. Gross, who broke her leg at the Valentine meeting, among those attending. Her leg was progressing according to schedule, although she still used a crutch, There was the usual slide show Saturday night, the rest of the time was for birding, including banding. The Executive Board decided to have the terms of members of the Records Committee start and expire with the spring meeting, rather than at the fall meeting, as at present
