Double negative media using interconnected Omega-type metallic particles

Eric Lheurette, O. Vanbesien, D. Lippens

We report on broadband low-loss properties of Ω-based metamaterials. It is shown that interconnecting elementary current-loops via their arms can yield to a relative bandwidth of around 70% for infinite arrays. Combining interconnected and disconnected sections permits one to engineer the left-…

Effect of growth temperature on defect states of GaNAsSb intrinsic layer in GaAs/GaNAsSb/GaAs photodiode for 1.3µm application

Satrio Wicaksono, Soon Fatt Yoon, Wan Khai Loke, Kianhuan Tan, Kim Luong Lew, Malek Zegaoui, Jean-Pierre Vilcot, Didier Decoster, Jean Chazelas

A GaAsSbN layer closely lattice matched to GaAs was used as an intrinsic layer (i layer) in a GaAsGaAsSbNGaAs p-i-n photodiode with response up to 1.3 μm. Deep level transient spectroscopy measurement on the GaAsGaAsSbNGaAs reveals two types of hole traps (HTs) in the GaAsSbN i layer; (i) HT1: a…

Spatially resolved Raman spectroscopy of single- and few-layer graphene

D. Graf, F. Molitor, K. Ensslin, C. Stampfer, A. Jungen, C. Hierold, L. Wirtz

We present Raman spectroscopy measurements on single- and few-layer graphene flakes. Using a scanning confocal approach we collect spectral data with spatial resolution, which allows us to directly compare Raman images with scanning force micrographs. Single-layer graphene can be distinguished from…
