After first investigations on the room temperature photoluminescence (PL) signal of porous Si [1,2], interest in the optical properties of semiconductor nanoparticles, especially porous Si and Si nanoparticles, has grown over the last decade [3,4]. Different processes for the synthesis of nanocrystalline Si (nc-Si) like Si ion implantation into high quality oxides [3], sputtering of Si-rich oxi...

according to the former researcher’s presented relations for flow through rock-fill porous media, the effects of physical characteristics was not studied separately. hence, due to the application of these relations, physical characteristics of porous materials effect must be investigated separately. in various constructed physical models of porous media, the effect of several variables such as ...

Arrays of thermoelectric bismuth telluride (Bi(2)Te(3)) nanowires were grown into porous anodic alumina (PAA) membranes prepared by a two-step anodization. Bi(2)Te(3) nanowire arrays were deposited by galvanostatic, potentiostatic and pulsed electrodeposition from aqueous solution at room temperature. Depending on the electrodeposition method and as a consequence of different growth mechanisms,...

Paul, Abhijeet, Purdue University, December 2011. Computational modeling and simulation study of electronic and thermal properties of semiconductor nanostructures. Major Professor: Gerhard Klimeck. The technological progress in dimensional scaling has not only kept Silicon CMOS industry on Moore’s law for the past five decades but has also benefited many other areas such as thermoelectricity, p...

Space localization of the linear and nonlinear optical properties in a transparent medium at the submicron scale is still a challenge to yield the future generation of photonic devices. Laser irradiation techniques have always been thought to structure the matter at the nanometer scale, but combining them with doping methods made it possible to generate local growth of several types of nanocrys...

Processing dye-sensitized solar cells gains more and more importance as interest in industrial applications grows daily. For large-scale processing and optimizing manufacturing in terms of environmental acceptability as well as time and material saving, a detailed knowledge of certain process steps is crucial. In this paper we concentrate on the sensitizing step of production, i.e., the anchori...
