Deep structural analysis of novel BGaN material layers grown by MOVPE

S. Gautier, G. Patriarche, T. Moudakir, M. Abid, G. Orsal, K. Pantzas, David Troadec, A. Soltani, L. Largeau, O. Mauguin, A. Ougazzaden

BGaN ternary alloys with 0.7% and 1.7% boron grown on GaN/sapphire template substrates by metalorganic vapour phase epitaxy (MOVPE) have been investigated through HAADF-STEM. At low boron content, 0.7%, no compositional fluctuations were observed with XRD or STEM measurements. Photoluminescence at...

Structural and optical properties of nanodots, nanowires, and multi-quantum wells of III-nitride grown by MOVPE nano-selective area growth

W.H. Goh, G. Patriarche, P.L. Bonanno, S. Gautier, T. Moudakir, M. Abid, G. Orsal, A.A. Sirenko, Z.-H. Cai, A. Martinez, A. Ramdane, L. Le Gratiet, David Troadec, A. Soltani, A. Ougazzaden

Nanodots, nanowires, and semi-polar quantum well structures of GaN-based material have been grown by nano-selective area growth (NSAG). The growth evolution of the nanostructure has been studied. Cross-sectional transmission electron microscopy (TEM) shows that the nanostructures are free of...

Epitaxial GaAs for X-ray imaging

G. C. Sun, R. Rao, S. Makham, J. C. Bourgoin, X. Y. Zhang, R. Gohier, F. Masiello, J. Haertwig, J. Baruchel, C. Ponchut, Andrea Balocchi, Xavier Marie, O. Gilard, Isabelle Roch-Jeune, J. C. Pesant

To be used for X-ray imaging, semiconductor materials must exhibit good and uniform electronic properties. Epitaxial layers are therefore better adapted than bulk materials which contain dislocations, precipitates and point defects in variable concentrations depending on the growth mode and the...
