Optical modulators based on Z-cut etched lithium niobate-on-insulator (Conference Presentation)

Eric Jun Hao Cheung, Aaron J. Danner, Shawn Yohanes Siew, El Hadj Dogheche, Bandar Alshehri

Active photonic devices such as high speed optical modulators are required in various applications such as fiber optic communications, frequency shifting and also in fiber optic gyroscopes for space systems. Bulk lithium niobate have primarily been used due to the lack of method of creating low...

Crystal facet engineering in Ga-doped ZnO nanowires for mid-IR plasmonics (Conference Presentation)

Vincent Sallet, Corinne Sartel, Said Hassani, Gaelle Amiri, Alain Lusson, Pierre Galtier, Isabelle Lefebvre, Christophe Delerue, Bruno Masenelli

The MOCVD growth of various Ga-doped ZnO (GZO) nanostructures for plasmonics is investigated, such as spontaneous or Au-catalyzed GZO nanowires, and ZnO/ZnO:Ga core/shell 1D structures. Indeed, in degenerate wide bandgap semiconductors such as n-type ZnO, the electron concentration can be tuned,...

Engineering the Ge/Si interface for defect-free III-V multi-junction solar cells on silicon

Youcef A Bioud, Meghan N Beattie, Abderraouf Boucherif, Romain Stricher, Serge Ecoffey, Gilles Patriarche, David Troadec, Ali Soltani, Nadi Braidy, Matthew Wilkins, Christopher E Valdivia, Karin Hinzer, Dominique Drouin, Richard Arès

Reducing the cost of III–V solar cells and enabling their direct integration on silicon can be achieved by depositing a thin, high-quality germanium (Ge) layer on low-cost Si substrates. However, the 4% lattice mismatch between Ge and Si poses a major challenge for direct epitaxial growth, leading...

Guided wave propagation in functionally graded cylindrical structures with sector cross-sections

Zhang Bo, Yu Jiangong, Jean-Etienne Lefebvre, Wei-Jiang Xu, Zhang Xiaoming, Ming Pingmei

The differential equations governing guided waves in functionally graded cylindrical structures with sector cross-sections are solved by introducing the double orthogonal polynomial series method into the cylindrical coordinate system, and the wave characteristics are subsequently investigated. The...

Efficient reduction of Cr(VI) under visible light irradiation using CuS nanostructures

Sawsen Nezar, Yacine Cherifi, Alexandre Barras, Ahmed Addad, El Hadj Dogheche, Nadia Saoula, Nadia Laoufi, Pascal Roussel, Sabine Szunerits, Rabah Boukherroub

Photoreduction of hexavalent chromium, Cr(VI), identified as carcinogenic and muta-genic element, to Cr(III), believed to be an essential element, using copper sulfide nanostructures (CuS NSs) as photocatalyst was investigated under visible light irradiation (k > 420 nm). The CuS NSs were...

Theoretical calculation of the instantaneous friction-induced energy losses in arbitrarily excited axisymmetric mechanical contact systems

Kevin Truyaert, Vladislav Aleshin, Koen van den Abeele, Steven Delrue

Abstract In this paper, we present the theoretical formula for calculating a friction-induced energy loss in a mechanical contact system consisting of two convex axisymmetric bodies subject to arbitrarily varying oblique loading. Non-flat contact geometry engenders a particular regime, partial slip...
