Title: Evidence for Possible Flexoelectricity in Tobacco Mosaic Viruses Used as Nanotemplates

Abstract

Electromechanical coupling in individual tobacco mosaic viruses has been studied using piezoresponse force microscopy. Possible origins of the observed high resolution contrast, including the topographic crosstalk, difference in the elastic properties, and the intrinsic electromechanical coupling due to the piezoelectric and flexoelectric effects are discussed. Using simple estimates, we argue that, due in part to the small size and high symmetry of this particular material system, flexoelectric coupling can dominate the observed electromechanical behavior. The electrical manipulation of the virus particles, essential for nanoelectronic applications for which they are proposed, has also been demonstrated.
