Time resolved photoluminescence studies of Zn–Se–Te nanostructures with sub-monolayer quantities of Te grown by molecular beam epitaxy

چکیده
We investigate triple-delta-doped ZnSe:Te samples grown with different Te/Zn flux ratios using timeresolved photoluminescence (TRPL). We show that the properties of the TRPL of both samples are consistent with the presence of quantum islands with a type-II band alignmrnt. Moreover, from the comparison of the PL, we show that higher Te/Zn flux ratio during the growth leads to the formation of larger quantum islands.

Quantum structures in Zn–Se–Te system containing submonolayer quantities of Te
In this paper we show that a multilayer Zn-Se-Te system, grown by molecular beam epitaxy in such a way as to contain sub-monolayer quantities of Te (so-called delta-doped ZnSe:Te), exhibits optical properties consistent with the presence of quantum size centers. We present results of excitation intensity and temperature dependent cw photoluminescence (PL) as well as time-resolved PL measurement...
متن کاملZn-Se-Te multilayers with submonolayer quantities of Te: Type-II quantum structures and isoelectronic centers
Detailed studies with spectral and time-resolved photoluminescence, photoluminescence excitation, and absorption spectroscopies show the formation of type-II quantum structures squantum dotsd in a Zn-Se-Te multilayer system with submonolayer quantities of Te. Moreover, it is shown that in addition to these quantum dots, Te isoelectronic centers are also present in the same material system and c...
متن کاملStructure of Zn–Se–Te system with submonolayer insertion of ZnTe grown by migration enhanced epitaxy
We here report results of high resolution x-ray diffraction, x-ray reflectivity XRR , as well as optical absorption and reflection measurements on ZnSe samples grown by molecular beam epitaxy, with insertion of planar regions of both N as an acceptor dopant and Te as a “co-dopant” to facilitate a p-type doping. We note that to enhance the surface diffusion of Te, migration enhanced epitaxy was ...
متن کاملPhotoluminescence of d-doped ZnSe:„Te,N... grown by molecular beam epitaxy
We have studied the low temperature photoluminescence ~PL! of a d-doped ZnSe:~Te,N! system using two different types of samples, one with single d layers separated by undoped spacers and the other with three adjacent d layers in each doping cycle. We have concluded that both Te and N participate in radiative recombination. We observe a relatively low PL efficiency ~compared to samples without N...
متن کاملHigh p-type doping of ZnBeSe using a modified delta-doping technique with N and Te
High crystalline quality ZnBeSe epilayers were grown nearly lattice matched to GaAs ~001! substrates by molecular beam epitaxy with a Be–Zn co-irradiation. A ~132! reflection high energy electron diffraction pattern was observed after the Be–Zn co-irradiation of the GaAs ~234! surface. A high p-type doping level of 1.5310 cm was achieved for ~N1Te! triple-delta doping ~d doping! of ZnBeSe epila...
