Ätzuntersuchungen an Verneuilspinellen

Abstract: Es wurde versucht, mittels der Ätztechnik die Qualität von Spinellsubstraten (Zusammensetzung MgO × 3,3‐3,5 Al2O3) der Orientierung (100), (110) und (111) zu erfassen. Die Ätzuntersuchungen ergaben, daß KHSO4, H3PO4 und Na2B4O7 auf der (111)‐Fläche und auf der (100)‐Fläche nur KHSO4 Versetzungsätzgruben bilden. Die auf den (100)‐, (111)‐ und (110)‐Flächen beim Ätzen entstandenen stäbchenförmigen Defekte wurden als Al2O3‐Ausscheidungen analysiert.

“…The hornogcneous film doping over the thickness was observed already a t the initial stages of deposition and, in fact, there was no TL. At the growth of epitaxial GaAs films the TIA formation is affected by the face polarity [65]. On the germanium surface the growth conditions of the layers (111)A and (111)B differed, oriented nuclei of different types were formed with different geometry of the growth steps.…”
