Improving the Relative Calculations of Volta Potential Differences Acquired from Scanning Kelvin Probe Force Microscopy (SKPFM) from Comparing an Inert Material to First-Principle Calculations [PDF]

ECS Transactions, 2018
An improved relative scaling of Volta potential differences (VPD) acquired from scanning Kelvin probe force microscopy (SKPFM) was developed by quantifying the probe work function. In corrosion studies, SKPFM has been used to identify local nobility of complex metallic systems and provide theoretical corrosion initiation sites.

Spontaneous Intercalation of Graphene on Sapphire. [PDF]

Small Methods
When left at room temperature, even in depressurized atmosphere, foreign molecular species can intercalate in between graphene and the (31$\sqrt {\mathbf {31}}$×$\times$31$\sqrt {\mathbf {31}}$)R9∘$^{\circ }$ reconstruction, effectively decoupling the graphene from its substrate: αAl2O3$\alpha {\rm Al}_2{\rm O}_3$(0001).
