Nachweis von Stapelfehlern in GaN‐Epitaxieschichten mittels Elektronenbeugung

Abstract: Mit der RHEED‐Technik werden auf {100}‐orientiertem Spinell epitaktisch aufgewachsene GaN‐Epitaxieschichten untersucht. Die Wachstumstemperaturen der Schichten waren 540 und 1035°C. Als Verwachsungsgesetz der Epitaxieschicht mit der Unterlage ergab sich Bei niedrigen Züchtungstemperaturen tritt Verzwillingung und eine hohe Stapelfehlerdichte auf. Bei hohen Temperaturen geht die Stapelfehlerdichte merklich zurück Zwillingsbildung ist nicht mehr nachweisbar.

“…The observed effect could result from either an increasing density of stacking faults or from an incomplete NH, decomposition, followed by the incorporation of N H species into the crystal. Stacking faults in the direction (1000) have been identified by RHEED in GaN epitaxy layers [ 5 ] . Since stacking faults are connected with a cubic sequence ABCA ... instead of the hexagonal sequence ABA ... (A, B, C denote double layers in binary crystals) they could be responsible for a stretch of the crystal toward the ideal ratio c / a = 1.633.…”
