In this paper a new method of in-situ detection of the high pressure phase transformation of semiconductor materials during dead-load scratching is described. This method is based on the simple fact that single crystal silicon is transparent to IR light while metallic materials are not transparent to IR radiation. The sample material used here is silicon, but the same approach can be applied to...

During the last two decades, the use of fluorescence in natural sciences has propelled a number of research fields, ranging from biological sciences and applications in the clinical sector (FISH for genetic testing, advanced sequencing technology) to environmental monitoring. In addition, the resulting technological developments have become important in several fields of materials sciences, for...

The nascent field of semiconductor optical fibers is attracting increased interest as a means to exploit the optoelectronic functionality of the semiconductor materials directly within the fiber geometry [1]. Compared to their planar counterparts, this new class of waveguide retains many of the advantageous properties of the fiber platforms such as robustness, flexibility, cylindrical symmetry,...

In recent years, the development of DSSC produced considerable research interest, including improving efficiency, packaging and flexible possibilities. Flexible possibility has great potential for all kinds of applications. Researches on the bendability of the solar cell thin sheets are mostly focus on the making the soft substrate or electrodes. Previous studies showed that coating method of T...

Wide bandgap power semiconductors such as SiC or GaN can safely operate at a junction temperature of 500°C. Such a high operating temperature range can substantially relax or completely eliminate the need for bulky and costly cooling components commonly used in silicon-based power electronic systems. However, a major limitation to fully realizing the potential of SiC and other wide band-gap sem...
