“…An alternating voltage is applied in order to obtain spatially resolved information about the electrical capacitance, which depends on the number density of mobile electrons and holes. This method has also allowed to investigate the nanoscopic conduction pathways for electrons and holes in electroluminescent polymers [14], in metal-insulatornanocomposites [15] and in networks of nanotubes [16].…”

Ion Dynamics / Electrostatic Atomic Force MicroscopyA nanoscopic technique based on electrostatic force spectroscopy in the time domain is introduced. This technique is used to characterize the ion dynamics in nanoscale subvolumes of solid electrolytes. Nanoscopic polarization spots can be created and directly visualized, and their time evolution can be studied. In the case of partially crystallized glass ceramics, the dynamic processes in different phases (glassy, crystalline and interface) can be distinguished and their activation energies and pre-exponential factors can be quantified. By applying grid-type spectroscopic measurements, maps of the local relaxation strength are obtained, giving information about the spatial distribution of the glassy and crystalline phase.

“…Park with various electrochemically polymerized conducting polymers such as polypyrrole [53][54][55], polyaniline [56,57], polythiophene and derivatives [58], and poly(3,4-ethylenedioxy-thiophene) [59], as well as chemically polymerized poly(o-anthranilic acid) (PARA) [60]. There have also been CS-AFM studies of chemically polymerized polyaniline [61,62] and MEH-PPV [63], as well as spin-coated poly(3,4-ethylenedioxythiophene) polystyrenesulfonate (PEDOT:PSS) [64,65]. All these studies universally suggested that the conducting polymer materials, both doped and undoped, showed a considerable nanoscale inhomogeneity and possessed domains with higher and lower conductivity.…”

Scanning probe microscopy (SPM) is a widely used experimental technique for characterizing and fabricating nanostructures on surfaces. In particular, due to its ability to spatially map variations in materials properties with nanometer spatial resolution, SPM is particularly well suited to probe the subcomponents and interfaces of hybrid nanomaterials, i.e., materials that are made up of distinct nanometer scale components with distinguishable properties. In addition, the interaction of the SPM tip with materials can be intentionally tuned such that local surface modification is achieved. In this manner, hybrid nanostructures can also be fabricated on solid substrates using SPM. This report reviews recent developments in the characterization and fabrication of hybrid nanomaterials with SPM. Specific attention is given to nanomaterials that consist of both organic and inorganic components including individual biomolecules mounted on inorganic substrates. SPM techniques that are particularly well suited for characterizing the mechanical and electrical properties of such hybrid systems in atmospheric pressure environments are highlighted, and specific illustrative examples are provided. This review concludes with a brief discussion of the remaining challenges and promising future prospects for this field.
