Highly confined radial contour modes in phononic crystal plate based on pillars with cap layers

Mohammed Moutaouekkil, Abdelkrim Talbi, El Houssaine El Boudouti, Omar Elmazria, Bahram Djafari-Rouhani, Philippe Pernod, Olivier Bou Matar

We investigate highly confined and isolated surface modes in a phononic crystal plate based on pillars with cap layers. The structure is made of a thin membrane supporting periodic pillars each composed of one cylinder surmounted by a disk shaped cap layer. An optimal choice of the geometrical…

Wide Band (0,5-67 GHz) Dielectric Properties of Biosourced Cellulose Ester Flexible Films

S.M. Li, Ghizlane Boussatour, Pierre-Yves Cresson, Benoit Genestie, Nicolas Joly, T. Lasri

In this work, the dielectric properties of a biosourced polymer are investigated. To that end, coplanar transmission lines were fabricated on a 600 μm thick cellulose palmitate substrate by using a transfer technique and photolithography. Then, the S-parameters of the transmission lines were…

On evaporation via an inclined rotating circular lift-off shadow or stencil mask

S. Arscott

A mathematical model is developed to calculate the topography of a mesa obtained by evaporation of matter via inclined rotating lift-off shadow masking. Two types of masking are considered: a circular mask and a cylindrical mask-the latter involves sidewall deposition. The model is able to predict…

Design and Implementation of Ternary Logic Integrated Circuits by Using Novel Two-Dimensional Materials

Mingqiang Huang, Xingli Wang, Guangchao Zhao, Philippe Coquet, Bengkang Tay

With the approaching end of Moore’s Law (that the number of transistors in a dense integrated circuit doubles every two years), the logic data density in modern binary digital integrated circuits can hardly be further improved due to the physical limitation. In this aspect, ternary logic (0, 1, 2)…

Transmorphic epitaxial growth of AlN nucleation layers on SiC substrates for high-breakdown thin GaN transistors

Jun Lu, Jr-Tai Chen, Martin Dahlqvist, Riad Kabouche, F Medjdoub, Johanna Rosen, Olof Kordina, Lars Hultman

ABSTRACT Interfaces containing misfit dislocations deteriorate electronic properties of heteroepitaxial wide bandgap III-nitride semiconductors grown on foreign substrates, as a result of lattice and thermal expansion mismatches and incompatible chemical bonding. We report grain-boundary-free AlN…

Towards all-solution-processed top-illuminated flexible organic solar cells using ultrathin Ag-modified graphite-coated poly(ethylene terephthalate) substrates

Shuanglong Wang, Yi Zhao, Hong Lian, Cuiyun Peng, Xuyong Yang, Yulai Gao, Yan Peng, Weixia Lan, Omar Ibrahim Elmi, Didier Stiévenard, Bin Wei, Furong Zhu, Tao Xu

All-solution-processed flexible organic solar cells (FOSCs) with high power conversion efficiency (PCE) are the prerequisite for application in low-cost, large-area, flexible, photovoltaic devices. In this work, high-performance, top-illuminated FOSCs using ultrathin Ag-modified graphite-coated…
