Optoelectronic characteristics of the superlattice diode as a function of deposition temperature and annealing conditions have been studied. The multilayer nanocrystalline silicon/adsorbed oxygen (nc/Si/O) superlattice formed by molecular beam epitaxy (MBE) system. Experimental results showed that deposition temperature of 550$^{\circ}C$, followed by hydrogen annealing leads to best results, in terms of optical photoluminescence (PL) and electrical current-voltage (I-V) characteristics. Consequently, the experimental results of multilayer Si/O superlattic device showed the stable photoluminescence and good insulating behavior with high breakdown voltage. This is very useful promise for Si-based optoelectronic devices, and can be readily integrated with conventional silicon ULSI processing.

Electrical characteristics of the Si-O superlattice diode as a function of annealing conditions have been studied. The nanocrystalline silicon/adsorbed oxygen superlattice formed by molecular beam epitaxy (MBE) system. Consequently, the experimental results of superlattice diode with multilayer Si-O structure showed the stable and good insulating behavior with high breakdown voltage. This is very useful promise for Si-based optoelectronic and quantum device as well as for the replacement of silicon-on-insulator (SOI) in ultra high speed and lower power CMOS devices in the future, and it can be readily integrated with silicon ULSI processing.

The photoluminescence (PL) characteristics of the silicon-oxygen(Si-O) superlattice formed by molecular beam epitaxy (MBE) were studied. To confirm the presence of the nanocrystalline Si structure, Raman scattering measurement was performed. The blue shift was observed in the PL peak of the oxygen-annealed sample, compared to the hydrogen-annealed sample, which is due to a contribution of smaller crystallites. Our results determine the right direction for the fabrication of silicon-based optoelectronic and quantum devices as well as for the replacement of silicon-on-insulator (SOI) in high-speed and low-power silicon MOSFET devices in the future.
