Many spectral responses in materials science, physics, and chemistry experiments can be
characterized as resulting from the superposition of a number of more basic individual …

We compare the three most commonly used scanning probe techniques to obtain a reliable
value of the work function in graphene domains of different thickness. The surface potential …

Surface potential and surface charge sensing techniques have attracted a wide range of
research interest in recent decades. With the development and optimization of detection …

Microscopic charge injection into the SiC/Si nanocrystals/SiC sandwiched structures through
a biased conductive AFM tip is subsequently characterized by both electrostatic force …

The energy band alignment in solar cell devices is critically important because it largely
