Graphite

Dual AC™ mode shows strikingly different contrast from the fundamental amplitude
and phase signals that are used in AC imaging mode. In this 10µm scan made of graphite,
“A” is the second mode (Dual AC) amplitude image, “B” is the fundamental amplitude,
“C” is the fundamental phase, and “D” is the height image. The second mode amplitude
shows striking contrast not visible in the other channels. Imaged with the MFP-3D AFM.
