Probing Stress Effects in Single Crystal Organic Transistors by Scanning Kelvin Probe Microscopy [PDF]
Applied Physics Letters, 2010 We report scanning Kelvin probe microscopy (SKPM) of single crystal difluoro bis(triethylsilylethynyl) anthradithiophene (diF-TESADT) organic transistors. SKPM provides a direct measurement of the intrinsic charge transport in the crystals independent of contact effects and reveals that degradation of device performance occurs over a time period of ...

A Duality Between Surface Charge and Work Function in Scanning Kelvin Probe Microscopy
Advanced Materials InterfacesScanning Kelvin probe microscopy (SKPM) is a powerful technique for macroscopic imaging of the electrostatic potential above a surface. Though most often used to image work‐function variations of conductive surfaces, it can also be used to probe the ...

Investigation of Hydrogen Evolution and Enrichment by Scanning Kelvin Probe Force Microscopy
Electrochemistry Communications, 2013 Abstract It has been a challenge to detect the real-time distribution of hydrogen at the micro-level. In this study, a scanning Kelvin probe force microscopy (SKPFM) was employed to characterize the surface potential changes induced by hydrogen. Variations of the surface potential were used to assess (a) the real-time distribution of hydrogen, (b ...
