Research Abstract

We have investigated the mechanisms of self assembled nano structures and obtained following results ;
1.We have calculated the wave functions for the modeled ridge QWR structures with mirror symmetry as well as the asymmetric structures, and discussed the polarization dependence of the optical transition. The polarization dependence of the ridge QWR is proved be vertical due to dependence on the special distribution of envelope wave functions of holes, and tilted by the existence of asymmetry caused by fluctuation in the QWR structure.
2.The MBE grown semiconductor corrugated structure on a (757)B plane is closely investigated by scanning transmission electron microscope (STEM). The cross section of the AlAs/GaAs SL and InGaAs layer on (757)B shows asymmetric corrugated structures, which is not observed in layers on (001). A strong corrugation of approximately 55 nm in lateral period and 5nm in height was observed in the upper side interface of InGaAs layer, which is stronger than of the lower side. This means InGaAs stronger tendency to corrugation, and stronger potential modulation in InGaAs channel, than in GaAs. On the other hand, AlAs/GaAs SL layers on the GaAs layer show smoothing, in which the height of corrugation reduces gradually, as the growth of the AlAs and the GaAs layers proceeds, although each AlAs layer seems traces exactly the morphology of the GaAs surface underneath.
3.Digital alloy, which replace the alloy by the short period super lattice (SL), was investigated to control nano structures. The AlAs/GaAs super lattices of various periods which equivalent to Al_xGa_<1-x> As alloy of x= 0.3, were prepared by MBE and characterized by XRD and PL. Optical properties such as PL energies and FWHMs show anomalous behavior when the SL has period of few MLs. Discussion by Kronig-Penney model differentiates MQW like SLs from alloy like SLs by their periods.
