Ferromagnetism in CuO-ZnO multilayers

Author(s)
C. Sudakar, K. Pradmanabhan, R Naik, G Lawes, Brian Kirby, Sanjiv Kumar, V. M. Naik
We investigated the magnetic properties of CuO–ZnO heterostructures to elucidate the origin of the ferromagnetic signature in Cu doped ZnO. The CuO and ZnO

Entangled Images from Four-Wave Mixing

Author(s)
Vincent Boyer, Alberto M. Marino, Raphael C. Pooser, Paul D. Lett
Two beams of light can be quantum mechanically entangled through correlations of their phase and intensity fluctuations. For a pair of spatially extended image

Ultra fast quantum key distribution over a 97-km installed telecom fiber with wavelength-division-multiplexing clock synchronization

Author(s)
Akihiro Tanaka, Mikio Fujiwara, Sae Woo Nam, Yoshihiro Nambu, Seigo Takahashi, Wakako Maeda, Ken-ichiro Yoshino, Shigehito Miki, Burm Baek, Z. Wang, Akio Tajima, Masahide Sasaki, Akihisa Tomita
We demonstrated ultra fast BB84 quantum key distribution (QKD) transmission at 625 MHz clock rate through a 97 km field-installed fiber using practical clock

On the Fluorescence From Integrating Spheres

Author(s)
Ping-Shine Shaw, Zhigang Li
Our recent study of the performance of integrating spheres shows prominent UV induced fluorescence features that are associated with contamination of the

Reversal mechanisms in perpendicular magnetic nanostructures

Author(s)
Justin M. Shaw, Stephen E. Russek, Michael J. Donahue, Thomas Thomson, Bruce Terris, Michael Schneider, Miles Olsen
We find that the reversal mechanism in magnetic nanostructures is highly dependent on the nature and condition of the edges. Temperature and size dependent

Nature of Transition Layers at the SiO2/SiC Interface

Author(s)
T Zheleva, Aivars Lelis, G Duscher, F Liu, Igor Levin, M Das
Electrical performance of SiC-based microelectronic devices is strongly affected by the densities of interfacial traps introduced by the chemical and structural

Inverted spectra of single-wall carbon nanotube films

Author(s)
John H. Lehman, Katie Hurst, Lara Roberson, K. Nield, J. D. Hamlin
We present absolute measurements of reflectance and absorbance for a purified single wall carbon nanotube (SWCNT) film. The absorbance spectrum of a SWCNT

Unconventional spin glass behavior in the pyrochlore Mn2Sb2O7

Author(s)
H. D. Zhou, C. R. Wiebe, A. Harter, Naresh S. Dalal, Jason Gardner
The new pyrochlore Mn2Sb2O7 has been synthesized via a low-temperature method to retain cubic Fd2m symmetry. The resulting material has an unconventional spin
