WebTapping Mode operation schematic. Stiff AFM cantilevers with force constants in the range of 10-100N/m and high resonance frequencies >190kHz are used for standard Tapping Mode operation. These AFM cantilevers do not suffer from sticking to the surface when measuring in ambient air. WebScanning Microwave Impedance Microscopy (sMIM) uses a microwave signal that is reflected from the tip-sample interface to elucidate the electrodynamic properties of the sample surface underneath the tip apex. Detecting and processing the reflectance in real-time allows sMIM to directly access the permittivity and conductivity of the material. kgi internships
