Structural phase transformations in metallic grain boundaries.
Structural transformations at interfaces are of profound fundamental interest as complex examples of phase transitions in low-dimensional systems. Despite decades of extensive research, no compelling evidence exists for structural transformations in high-angle grain boundaries in elemental systems. Here we show that the critical impediment to observations of such phase transformations in atomis...
متن کاملElectrical Properties of Grain Boundaries
The electrical properties of grain boundaries are very different in insulators, semiconductors and metals. We present them briefly in the case of insulators and semiconductors and with more details in the case of metals.
متن کاملInfluence of Grain Boundaries on the Vibrational Properties of Silver Nanowires
Metal and semiconductor nanowires (NWs) have been widely employed as the building blocks of the nanoelectromechanical systems, which usually acted a resonant beam. Recent researches reported that nanowires are often polycrystalline, which contains grain boundaries (GBs) that transect the whole nanowire into a bamboo like structure. Based on the larger-scale molecular dynamics (MD) simulations, ...
متن کاملElectronic properties of grain boundaries in semiconductors
2014 The aim of this communication is to describe the main results which we have obtained in the past years on the electronic properties of grain boundaries in semiconductors. The study, experimental as well as theoretical, has focused on the main electronic characteristics i.e. density of states, optical cross sections, carrier capture cross sections (and recombination velocity) from which all...
متن کاملThermoelectric Properties of Functionalized Graphene Grain Boundaries
Thermoelectric effect enables direct conversion between thermal and electrical energy and provides an alternative route for power generation and refrigeration. Hereby it is important to find materials with a high thermoelectric performance. In this sense, in the present work, we study the behavior of the thermoelectric properties of functionalized graphene grain boundaries by employing non-equi...
