Dispersive charge transport along the surface of an insu - lating layer observed by Electrostatic Force Microscopy
– We report the observation in the direct space of the transport of a few thousand charges submitted to a tunable electric field along the surface of a silicon oxide layer. Charges are both deposited and observed using the same Electrostatic Force Microscope. During the time range accessible to our measurements (i.e. t = 1 ∼ 1000 s), the transport of electrons is mediated by traps in the oxide....
متن کاملCharge Patterning on Sapphire Studied by Electrostatic Force Microscopy
The ability of insulating materials to trap charges is a phenomenon of interest in many technological fields such as information storage, electron beam lithography and formation of electrets for instance. However, charge-trapping characteristics are not well understood in spite of a large amount of studies carried out mainly by scanning electron microscopy (SEM) [1,2] and more recently by atomi...
متن کاملLocal charge transport in two-dimensional PbSe nanocrystal arrays studied by electrostatic force microscopy.
Two-dimensional PbSe nanocrystal arrays on silicon nitride membranes were investigated using electrostatic force microscopy (EFM) and transmission electron microscopy (TEM). Changes in lattice and transport properties upon annealing in a vacuum were revealed. Local charge transport behavior was directly imaged by EFM and correlated to nanopatterns observed with TEM. Charge transport through nan...
متن کاملNanoscale electric polarizability of ultrathin biolayers on insulating substrates by electrostatic force microscopy.
We measured and quantified the local electric polarization properties of ultrathin (∼5 nm) biolayers on mm-thick mica substrates. We achieved it by scanning a sharp conductive tip (<10 nm radius) of an electrostatic force microscope over the biolayers and quantifying sub-picoNewton electric polarization forces with a sharp-tip model implemented using finite-element numerical calculations. We ob...
متن کاملDielectric properties of thin insulating layers measured by Electrostatic Force Microscopy
In order to measure the dielectric permittivity of thin insulting layers, we developed a method based on electrostatic force microscopy (EFM) experiments coupled with numerical simulations. This method allows to characterize the dielectric properties of materials without any restrictions of film thickness, tip radius and tip-sample distance. The EFM experiments consist in the detection of the e...
