X-MoS2/GO/Graphene Heterostructures and Doping Effects: KPFM Based Study of Surface Potential
Biointerface Research in Applied ChemistryIn this work, we report the contact potential difference measured by Kelvin probe force microscopy of phosphorus-doped Si/MoS2/graphene and Si/MoS2/GO with different thicknesses deposited using micro drop casting and chemical vapor deposition. Doping with 15% phosphorus increased the surface potential of the layers. The readings obtained were from -722.

Advanced Science, EarlyView.Few‐layer La2CoO4 nanosheets are produced via phonon‐resonance‐assisted cleavage of the rock‐salt layers in the Ruddlesden‐Popper structure under the 20 kHz resonance condition, enabling controlled exfoliation into ultrathin sheets. The nanosheets show improved gas‐sensing capability, delivering an 86.67% response to 1 ppm NO2 at room temperature ...

AFM-assisted fabrication of thiol SAM pattern with alternating quantified surface potential
Nanoscale Research Letters, 2011 Thiol self-assembled monolayers (SAMs) are widely used in many nano- and bio-technology applications. We report a new approach to create and characterize a thiol SAMs micropattern with alternating charges on a flat gold-coated substrate using atomic ...

Advanced Science, EarlyView.The redox‐active nature of NiOx enables ultrafast oxidative doping of spiro‐OMeTAD within seconds. Concurrently, NiOx‐Li+ coordination complexes formed during this redox process are selectively removed by filtration, effectively extracting residual Li+ ions from the film.

Diffusion of Pb on Si studied by SFM and KPFM
Nanostructuring of surfaces, self-organization of structures and low dimensional systems are just a few points for which a precise understanding of diffusion, in particular surface diffusion, is important [1, 2, 3]. Pb/Si(111)-(7 × 7) exhibits unexpectedly fast diffusion.

Advanced Science, EarlyView.This study demonstrates a dual‐functional porphyrin‐based passivation molecule, [12]‐C‐4POR, capable of simultaneously coordinating Pb2+ and Li+ ions through its porphyrin core and crown ether moiety, respectively. This molecule effectively reduces trap‐state density, suppresses non‐radiative recombination, and mitigates Li+ migration at the perovskite/
