چکیده

The authors report the growth of ZnSe/ZnSeTe superlattice nanotips on oxidized Si(100) substrate. It was found the nanotips exhibit mixture of cubic zinc-blende and hexagonal wurtzite structures. It was also found that photoluminescence intensities observed from the ZnSe/ZnSeTe superlattice nanotips were much larger than that observed from the homogeneous ZnSeTe nanotips. Furthermore, it was found that activation energies for the ZnSe/ZnSeTe superlattice nanotips with well widths of 16, 20, and 24 nm were 76, 46, and 19 meV, respectively.

Self-organized superlattice formation in II-VI and III-V semiconductors

There is extensive recent experimental evidence of spontaneous superlattice (SL) formation in various II-VI and III-V semiconductors. Here we propose an atomistic mechanism responsible for SL formation, and derive a relation predicting the temperature, flux and miscut dependence of the SL layer thickness. Moreover, the model explains the existence of a critical miscut angle below which no SL is...

Pressure and temperature tuning of the valence band offset in cubic superlattices: The effects of piezoelectric fields

Theoretical calculations have been performed to study the effects of piezoelectric fields in superlattice systems. The results show that cubic strained superlattices and quantum wells subjected to variable temperature and pressure exhibit changes in their piezoelectric fields. We consider superlattice systems grown in arbitrary directions, with a thickness smaller and larger than the critical t...

Heavily p-Type Doped ZnSe Using Te and N Co Doping

A lot of progress has been made on the fabrication of solid-state light emitters; however, there is a spectral gap in the green-yellow region (530–590 nm) with all commercially available devices. This spectral region is important for many emerging applications, such as the use of plastic-optical fibers, that require green lasers to achieve the lowest attenuation coefficient. Thus, ZnSe-based de...

Design Guidelines for True Green LEDs and High efficiency Photovoltaics Using ZnSe/GaAs Digital Alloys

In the fields of solid state lighting and high efficiency solar photovoltaics (PV), a need still exists for a material system that can target the 2.3-2.5eV energy range. The ZnSe/GaAs system is shown to have great potential. The digital alloy approach can be utilized as a well-ordered design alternative to the disordered alloyed systems. The effective band-gap of the ZnSe/GaAs(001) superlattice...

Monte Carlo simulation of sinusoidally modulated superlattice growth.

The fabrication of ZnSe/ZnTe superlattices grown by the process of rotating the substrate in the presence of an inhomogeneous flux distribution instead of the successively closing and opening of source shutters is studied via Monte Carlo simulations. It is found that the concentration of each compound is sinusoidally modulated along the growth direction, caused by the uneven arrival of Se and T...
