We present the micro-Raman study of curved Ge/sub x/Si/sub 1-x//Ge/sub y/Si/sub 1-y/ heterostructure, and found the strain of the curved thin layer is proportional to the curvature, i.e. inversely proportional to the diameter.

We will discuss CVD growth, characterization and properties of novel Ge/sub 1-z/Sn/sub z//Ge/sub 1-x-y/Si/sub x/Sn/sub y/ heterostructures on Si(100). The Ge/sub 1-x-y/Si/sub x/Sn/sub y/ system provides independent strain and bandgap engineering to achieve structures that may lead to novel photonic group-IV devices.

This study proposes a different approach of much simpler THz emitters based on radiative impurity transitions in doped silicon devices fabricated without Ge alloying. This work has gathered the electroluminescence at 4.2 K from a boron doped sample. The current versus voltage characteristics are measured at the same pulse conditions using an inductive probe and oscilloscope.

This paper discusses the state of the art as well as the approach for light coupling, switching and modulating on Si. These results are based on sub-micron highly confined structures. It is primarily this principle, of manipulating light by confinement, that has enabled light control and coupling on silicon using ultra-compact structures.

This study performs experiments on ultrathin Si capping on Ge quantum dots at varying growth temperature to clarify the growth details of GeSi quantum rings on Si [001]. Results show that at a lower temperature of 400/spl deg/C with several angstroms thick Si capping, the shape of dots remains domed, but at a higher temperature of 640/spl deg/C, the shape changes from dome to pyramid. This phenomenon shows that the shape transition is highly dependent on temperature and Ge atom diffusion and Ge atom segregation play an important role in quantum ring formation. This is confirmed by the results of grazing incidence X-ray diffraction.

We review devices, fabricated using room-temperature solution spin-casting compatible with silicon post-processing, which produce, detect, modulate, and process optical signals in the spectral range from 1200-1700 nm. We first summarize the synthesis of PbS (lead sulphide) quantum dot nanocrystals 2-10 nm in diameter by solution chemistry. We then discusses the realization to date of solution-processed, silicon-compatible thin-film devices fabricated using these materials.
