Agarose-stabilized gold nanoparticles for surface-enhanced Raman spectroscopic detection of DNA nucleosides
(American Institute of Physics, 2006)We present surface-enhanced Raman scattering (SERS) studies of DNA nucleosides using biologically benign agarose-stabilized gold nanoparticles (AAuNP). We compare the SERS activity of nucleosides with AAuNP to that of ... -
Coherent control of intersubband optical bistability in quantum wells
(American Institute of Physics, 2004)We present a study of the nonlinear intersubband (ISB) response of conduction electrons in a GaAs/Al0.3Ga0.7As quantum well to strong terahertz (THz) radiation, using a density-matrix approach combined with time-dependent ... -
Electric field and temperature-induced removal of moisture in nanoporous organosilicate films
(American Institute of Physics, 2004)The effects of bias-temperature-stress (BTS) or simply temperature-stress (TS) on nanoporous low-k methylsilsesquioxane films are studied. Initially, the as-given and O2 ashed/etched films exhibit physical adsorption of ... -
Erratum: “Generation of fast propagating combustion and shock waves with copper oxide/aluminum nanothermite composites” [ Appl. Phys. Lett. 91, 243109 (2007) ]
(American Institute of Physics, 2008)Another erratum concerning “Generation of fast propagating combustion and shock waves with copper oxide/aluminum nanothermite composites” [ Appl. Phys. Lett. 91, 243109 (2007) ]. -
Erratum: “Generation of fast propagating combustion and shock waves with copper oxide/aluminum nanothermite composites” [Appl. Phys. Lett. 91, 243109 (2007)]
(American Institute of Physics, 2008)Erratum concerning “Generation of fast propagating combustion and shock waves with copper oxide/aluminum nanothermite composites” [Appl. Phys. Lett. 91, 243109 (2007)]. -
Generation of fast propagating combustion and shock waves with copper oxide/aluminum nanothermite composites
(American Institute of Physics, 2007)Nanothermite composites containing metallic fuel and inorganic oxidizer are gaining importance due to their outstanding combustion characteristics. In this paper, the combustion behaviors of copper oxide/aluminum nanothermites ... -
Harvesting triplet excitons for application in polymer solar cells
(American Institute of Physics, 2009)Triplet enhanced ladder-type poly (para-phenylene) polymer (PhLPPP) with covalently bound trace amounts of palladium blended with a fullerene derivative [[6,6]-phenyl C61-butyric acid methyl ester (PCBM)] shows power ... -
Initial growth of interfacial oxide during deposition of HfO2 on silicon
(American Institute of Physics, 2004)Interfacial chemistry of Hf∕Si, HfO2∕SiO2∕Si, and HfO2∕Si is investigated by x-ray photoelectron spectroscopy in order to understand the interfacial layer formation mechanism. Deposition of Hf and HfO2 films was carried ... -
Nanoclustering of vacancies in thin metal films revealed by x-ray diffuse scattering
(American Institute of Physics, 2007)The authors report the incorporation of unexpectedly large vacancy clusters into homoepitaxial Ag(001) films. These results, which are for a simple noble metal system, have important implications for understanding the ... -
Permittivity enhancement of aluminum oxide thin films with the addition of silver nanoparticles
(American Institute of Physics, 2006)Multilayer reactive electron-beam evaporation of thin aluminum oxide layers with embedded silver nanoparticles (Ag-nps) has been used to create a dielectric thin film with an enhanced permittivity. The results show a ... -
Unipolar spin diodes and transistors
(American Institute of Physics, 2000)Unipolar devices constructed from ferromagnetic semiconducting materials with variable magnetization direction are shown theoretically to behave very similarly to nonmagnetic bipolar devices such as the p-n diode and the ... -
Vacancy trapping and annealing in noble-metal films grown at low temperature
(American Institute of Physics, 2002)We have used synchrotron x-ray diffraction to study the homoepitaxial growth on Cu(001), Ag(001), and Ag(111), at temperatures between 300 and 65 K. The growth on all of these surfaces exhibits a consistent trend towards ... -
Wetting-layer transformation for Pb nanocrystals grown on Si(111)
(American Institute of Physics, 2004)We present the results of in situ x-ray scattering experiments that investigate the growth of Pb nanocrystalline islands on Si(111). It is conclusively shown that the Pb nanocrystals do not reside on top of a Pb wetting ...
