Acoustic Spectroscopy of Materials and Structures for Electrical Engineering

The methods of acoustic spectroscopy are powerful tool for the study physical properties of condensed matter. The ability of these methods makes it possible to obtain important information for variety of materials concerning not only their mechanical properties. The theoretical principles of acoustic spectroscopy of some kinds of materials and structures perspective for application in electrica...

Interdisciplinary Approaches towards Materials with Enhanced Properties for Electrical Engineering

The internationally growing demand for electrical energy is one of the most prominent triggers stimulating research these days. In this highly interdisciplinary research area, electrical engineers, material scientists and chemists collaborate for the design and fabrication of the next generation of high-voltage machinery and electro-technical devices. Nanocomposites with enhanced thermal conduc...

Nanocrystalline Ge Flash Memories: Electrical Characterization and Trap Engineering

A single transistor memory structure with threshold voltage shift, Vth, exceeding ~1.5 V corresponding to interface charge trapping in nanocrystalline germanium (ncGe), operating at 0.96 MV/cm, is presented. The trapping effect is eliminated when nc-Ge is synthesized in forming gas thus excluding the possibility of quantum confinement and Coulomb blockade effects. Through discharging kinetics, ...
