Impact of gravity-related phenomena on the grain structure formation: comparative study between horizontal and vertical solidification of a refined Al-20wt.%Cu alloy

Autor: Guillaume Reinhart, M.C. Benoudia, H. Soltani, M. Zahzouh, Henri Nguyen-Thi

Publikováno v: IOP Conference Series: Materials Science and Engineering. 529:012019

On earth, gravity-related phenomena are unavoidable, such as thermo-solutal convection caused by density gradients in the melt and buoyancy when the liquid phase is denser than the solid phase. Such phenomena can drastically affect both the grain den

Chemical beam epitaxy of high purity InP using tertiarybutylphosphine and 1,2 bis-phosphinoethane

Autor: G. Hincelin, M. Zahzouh, R. Mellet, A.M. Pougnet

Publikováno v: Materials Science and Engineering: B. 21:165-168

This paper compares tertiarybutylphosphine (TBP), and 1,2 bis-phosphinoethane (BPE) as phosphorus precursors for the growth of InP in chemical beam epitaxy. The thermal decomposition of both sources in a low pressure cracking cell produces dimer P2 a

Growth of InP in chemical beam epitaxy with high purity tertiarybutylphosphine

Autor: G. Hincelin, M. Zahzouh, R. Mellet, A.M. Pougnet

Publikováno v: Journal of Crystal Growth. 120:119-123

InP layers were grown by chemical beam epitaxy (CBE) using high purity thermally precracked tertiarybutylphosphine (TBP) and trimethylindium (TMI) as the source of the group III element. For optimized substrate temperature and V/III ratio, InP films

Non linear simulation and measurement of microwave fibre-optic links

Autor: M Zahzouh, M Krakowski, Christian Rumelhard

Publikováno v: 25th European Microwave Conference, 1995.

We present in this paper a model of fibre-optic link at microwave frequencies which is implemented in a frequency-domain non linear simulator (MDS). Comparison between simulated and experimental results is made for the static response and the relativ
