Mechano-Triboelectric Analysis of Surface Charge Generation on Replica-Molded Elastomeric Nanodomes

Micromachines, 2021
Replica molding-based triboelectrification has emerged as a new and facile technique to generate nanopatterned tribocharge on elastomer surfaces. The “mechano-triboelectric charging model” has been developed to explain the mechanism of the charge ...

Determination of High Frequency Dielectric Constant and Surface Potential of Graphene Oxide and Influence of Humidity by KPFM.

, 2015
peer reviewedWe use Kelvin probe force microscopy (KPFM) and capacitance coupling (dC/dz) to study the electrical properties of graphene oxide (GO). We propose using the dC/dz signal to probe the high frequency dielectric constant of mono- and few-layer ...

Note: Switching crosstalk on and off in Kelvin probe force microscopy [PDF]

, 2014
In Kelvin Probe Force Microscopy (KPFM) electronic crosstalk can occur between the excitation signal and probe deflection signal. Here, we demonstrate how a small modification to our commercial instrument enables us to literally switch the crosstalk on ...

Controlling Surface Potential of Graphene Using dc Electric Field [PDF]

, 2016
In this work, we study surface potential of graphite deposited on SiO2/Si substrate using Kelvin Probe Force Microscopy (KPFM) and Electric Force Microscopy (EFM). The amplitude modulated KPFM (AM-KPFM) shows that the graphene layer work function is 4.69±
