ZnSe/ZnMgSSe quantum well (QW) structures with an abrupt heterointerface have successfully been grown on [100]-oriented GaAs substrates by metalorganic molecular beam epitaxy (MOMBE) under in situ observation of reflection high energy electron diffraction (RHEED). Source materials used were elemental zinc (Zn), selenium (Se), the RHEED specular spot were observed over 10 cycles during the growth of ZnSe well and ZnMgSSe barrier layers. A series of single quantum wells (SQWs) with various well widths were grown and characterized by photoluminescence (PL) measurements at 4.2 K. SQWs with 24 and 33 Å well widths exhibited sharp intense emissions which originated from n=1 heavy-hole free excitons. © 1995, All rights reserved.

Time-resolved nonlinear luminescence of biexcitons in ZnSe-ZnxMg1-xSySe1-y single quantum wells

Nonlinear optical properties of dense excitonic systems in ZnSe-ZnxMg1-xSySe1-y single quantum wells have been studied by means of time-resolved nonlinear luminescence spectroscopy, based on an excitation correlation technique. The enhancement in luminescence efficiency of biexcitons was clearly observed in a time-correlation trace of nonlinear biexciton luminescence. The origin of the enhancement was attributed to the stimulation of biexciton luminescence. © 1995 The American Physical Society.

Optical properties of ZnSe/ZnMgSSe single quantum wells grown by metalorganic molecular beam epitaxy

In this letter we report optical properties of ZnSe/ZnMgSSe single quantum wells (SQWs) grown by metalorganic molecular beam epitaxy (MOMBE). At 4.2 K, a 10.5 monolayer (30 Å) ZnSe SQW confined in Zn0.90Mg0.10-S0.18Se0.82 layers exhibited intense purplish blue photoluminescence (PL) peaking at 2.865 eV, whose linewidth was as small as 5 meV. This emission was assigned to the n=1 heavy-hole exciton (.Ex1hh)- Another peak appeared on the low-energy side of Ex1hh under high excitation and grew nonlinearly with increasing excitation intensity. We tentatively attribute this line to the recombination of biexcitons. The exciton-longitudinal-optical(LO)-phonon coupling constant was also assessed from the temperature dependence of PL measurements. © 1994 The Japan Society of Applied Physics.

Gas-source molecular beam epitaxial growth of (zn, mg)(s, se) using bis-methylcyclopentadienyl-magnesium and hydrogen sulfide

Suda J., Kawakami Y., Fujita S., Fujita S.

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：Japanese Journal of Applied Physics

In this letter we report the first successful gas-source molecular beam epitaxy (GSMBE) of ZnMgSSe on (100) GaAs substrates. Source materials used were elemental zinc (Zn), elemental selenium (Se), hydrogen sulfide (H2S) and bis-methylcyclopentadienyl-magnesium ((MeCp)2Mg). It is revealed that the growth by this technique results in good controllability of solid compositions of this quaternary alloy system. Photoluminescence and X-ray diffraction measurements show that the layer coherently grown on GaAs exhibits high quality comparable to that grown by conventional molecular beam epitaxy (MBE). © 1994 The Japan Society of Applied Physics.
