Impact of Electrostatic Forces in Contact Mode Scanning Force Microscopy [PDF]
Physical Review B, 2010 In this $\ll$ contribution we address the question to what extent surface charges affect contact-mode scanning force microscopy measurements. % We therefore designed samples where we could generate localized electric field distributions near the surface ...

Characterization of Dielectric Nanocomposites with Electrostatic Force Microscopy. [PDF]
Scanning, 2017 Nanocomposites physical properties unexplainable by general mixture laws are usually supposed to be related to interphases, highly present at the nanoscale. The intrinsic dielectric constant of the interphase and its volume need to be considered in the prediction of the effective permittivity of nanodielectrics, for example.

Electrostatic force microscopy for the accurate characterization of interphases in nanocomposites [PDF]
Beilstein Journal of Nanotechnology, 2018 The unusual properties of nanocomposites are commonly explained by the structure of their interphase. Therefore, these nanoscale interphase regions need to be precisely characterized; however, the existing high resolution experimental methods have not ...

Electrostatic tip-dielectric sample interaction in electrostatic force microscopy
Revista Facultad de Ingeniería Universidad de Antioquia, 2013 Electric force microscopy is a local technique for measuring electrical properties of materials. The electrostatic force gradient measurements on dielectric samples are sensitive not only to the initial charge distribution in the sample but also to the ...

Time-dependent measurement of plasmon-induced charge separation on a gold nanoparticle/TiO2 interface by electrostatic force microscopy [PDF]
Scientific Reports, 2022 Plasmon-induced charge separation (PICS) is an efficient way to use the hot carriers generated by localized surface plasmon resonance. Although the ultrafast dynamics of hot carrier generation and annihilation itself are well understood, the slow ...
