“…The other one, at 33.11, is most likely coming from the 0.21-0.25 mm thick heavily phosphorous-doped Ge layer on top ([P]¼3.6 Â 10 20 cm À 3 ). The asymmetry of the Ge (main) peak is to be noticed: the high incidence angle component is indeed due to the interfacial GeSi alloy formed during the short duration thermal cycling [16].…”

“…The overall thickness of our intrinsic Ge and Ge:B layers were 1.28 mm and 1.16 mm, respectively. Short duration 750 1C/890 1C H 2 thermal cycling was used afterwards in order to reduce threading defect densities while keeping smooth surfaces and minimizing Si out-diffusion into the Ge or Ge:B layers [16].…”

“…Сравнение образцов со слоями Ge одинаковой толщины, выращенных на отклоненных и неотклоненных подлож-ках Si, не выявило существенных различий в значениях плотности прорастающих дислокаций. Кроме того, при выбранных условиях отжига (и толщине слоя Ge) про-цесс диффузии Si из подложки практически не затраги-вает верхний, приповерхностный слой Ge, на котором впоследствии осуществляется рост слоев A III B V [16]. Высокое качество получаемых виртуальных подложек Ge/Si также подтверждается данными рентгеновской дифракции, согласно которым слои Ge характеризуются малой шириной кривой качания (∼ 0.05…”
