HD-KFM

HD-KFM is characterized because the electric feedback is tuned to the second eigenmode frequency of the cantilever. HD-KFM is based the first flexural eigenmode of the cantilever is excited mechanically and the second flexural mode is excited electrically. In the past decade, multi-frequency approach has become one of the front-end topics amongst the AFM community as it has shown many potential applications

• One pass – NO LIFT : Very high sensitivity & higher spatial resolution

• Surface potential mapping

• 2nd lock-in amplifier

• Applications:
• Materials, semiconductors, batteries…
