理论
- Thermal Tune: Detect the natural resonant frequency of the cantilever by doing an interactive series of frequency sweeps and averaging them. A real-time amplitude v.s. frequency (power spectrum) plot coms up.大部分的drive frequency for AC mode cantilever在50kHz-400kHz的范围(气相)。
- Amplitude modulation也叫Tapping mode, intermitent contact mode, dynamic force mode.
- 镀Al的tip不宜用于液相,背面镀Au或全部镀Au的可以。
