We studied the growth of QDSLs (Quantum Dots Superlattices) made of Ti5Si3 quantum dots inside an “n” doped SiGe thin film matrix using a commercial Chemical Vapor Deposition (CVD) apparatus. To our knowledge, it is the first time these kinds of materials are produced. XRD, SEM and TEM images were employed to characterize the obtained materials. As predicted by the theory, the inclusion of these particles...
An innovation approach to thermal energy harvesting is presented. It consists of a two step conversion of heat into electricity. The new technique can be used for powering ultra-low power electronics and autonomous systems. One of the keys to improve the generated power density is downscaling of individual devices. Laws modeling downscaling have been established in this paper and show that the miniaturization...
