چکیده

We introduce the concept of scanning flow-impedance microscopy (SFIM) which is an imaging technique based on hydrodynamics. Using a simple experimental setup including a mass flow controller and a manometer, the operating principle of SFIM is validated under atmospheric pressure and temperature conditions. Experimental results show that the flow impedance strongly depends on the relative distance between a probe and a specimen. SFIM micrographs of microscale patterns with various linewidths are presented.

Scanning impedance microscopy (SIM): A novel approach for AC transport imaging

Scanning Impedance Microscopy (SIM) is one of the novel scanning probe microscopy (SPM) techniques, which has been developed to taking image from sample surface, providing quantitative information with high lateral resolution on the interface capacitance, and investigating the local capacitance–voltage (C–V) behavior of the interface and AC transport properties. The SIM is an ordinary AFM equip...

Scanning Impedance Microscopy: From Impedance Spectra to Impedance Images

Impedance spectroscopy has long been recognized as one of the major techniques for the characterization of ac transport in materials. The primary limitation of this technique is the lack of spatial resolution that precludes the equivalent circuit elements from being unambiguously associated with individual microstructural features. Here we present a scanning probe microscopy technique for quant...

An Electrochemical Sensor for the determination of Uric Acid based on CdSe Quantum Qots (QDs) / Graphene Oxide (GO) nanocomposite

A chemically modified electrode has been constructed based on CdSe QDs/GO nanocomposite and employed for the selective determination of Uric acid (UA) in 0.1M Phosphate buffer solution, (PBS, pH 7.0). Field emission scanning electron microscope (FESEM) was applied to characterize the surface morphology and the performance of the modified electrode was examined by cyclic voltammetry (CV) and ele...

Scanning hall probe microscopy technique for investigation of magnetic properties

Scanning Hall Probe Microscopy (SHPM) is a scanning probe microscopy technique developed to observe and image magnetic fields locally. This method is based on application of the Hall Effect, supplied by a micro hall probe attached to the end of cantilever as a sensor.  SHPM provides direct quantitative information on the magnetic state of a material and can also image magnetic induction under a...
