|Title:||Large electromechanical response in silicon nanowires predicted from first-principles electronic structure calculations|
|Abstract:||We study by means of first-principles electronic structure calculations the electromechanical response, i.e., the structural modifications upon charge injection, of < 100 > silicon nanowires. We show that, at variance with sp(2) carbon nanostructures, the response is remarkably linear, discriminates between injected charge of different signs, and is up to one order of magnitude larger than in carbon nanotubes.|
