Inverse heterodyne effect in bimodal Kelvin probe force microscopy
Hugo Valloire, Sylvain Clair, Christian Loppacher +2
Heterodyne Kelvin probe force microscopy (He-KPFM) enables high-sensitivity electrostatic measurements by converting a bias-modulated interaction into a resonant response at a high…
