摘要: The effects of V/III ratio and seed window orientation on the coalescence epitaxial lateral overgrowth InP over SiO2 using metal organic vapor-phase epitaxy with tertiary butyl phosphine were investigated. Parallel lines having θ = 60° 30° off [0\( \bar{1} \)1] coalesced, their growth rate variation was measured. Coalescence separated by narrow angles in a star-like pattern also studied. We find greatest extent to occur when stripe is oriented just ⟨010⟩ directions. strongly affects coalescence, showing an alternating enhancement or inhibition depending which side direction stripes are oriented. quality coalesced material between examined cross-sectional transmission electron microscopy, illustrating most problematic directions under two conditions.
