Zusammenfassung

Depending on the composition of [001] oriented short period SimGen superlattices (m monolayers Si/n monolayers Ge) there are six different space groups. In case of m+n odd the microscopic periodicity is doubled to 2(m+n) monolayers due to the tetrahedral bonding. We prepared several superlattices namely Si2Ge3, Si3Ge3 and Si4Ge6 with low temperature molecular beam epitaxy. Using selected area ...
