High-bandwidth multimode self-sensing in bimodal atomic force microscopy.

Beilstein journal of nanotechnology

Ruppert MG, Moheimani SO.
PMID: 26977385
Beilstein J Nanotechnol. 2016 Feb 24;7:284-95. doi: 10.3762/bjnano.7.26. eCollection 2016.

Using standard microelectromechanical system (MEMS) processes to coat a microcantilever with a piezoelectric layer results in a versatile transducer with inherent self-sensing capabilities. For applications in multifrequency atomic force microscopy (MF-AFM), we illustrate that a single piezoelectric layer can...

PMID: 23464216
Rev Sci Instrum. 2013 Feb;84(2):023705. doi: 10.1063/1.4790474.

Atomic Force Microscopes (AFM) are used for generating surface topography of samples at micro to atomic resolutions. Many commercial AFMs use piezoelectric tube nanopositioners for scanning. Scanning rates of these microscopes are hampered by the presence of low frequency...

Note: Piezoelectric strain voltage sensing at ultra-low frequencies.

The Review of scientific instruments

Laskovski A, Moheimani SO, Yuce MR.
PMID: 21895291
Rev Sci Instrum. 2011 Aug;82(8):086113. doi: 10.1063/1.3628664.

Piezoelectric sensors have emerged as a versatile tool for measurement of various quantities such as pressure, acceleration, strain, or force across many industrial applications. When mechanically strained, electric charges are produced inside a piezoelectric transducer. These charges result in...

Rosette-scan video-rate atomic force microscopy: Trajectory patterning and control design.

The Review of scientific instruments

Nikooienejad N, Maroufi M, Moheimani SOR.
PMID: 31370473
Rev Sci Instrum. 2019 Jul;90(7):073702. doi: 10.1063/1.5098499.

We present an analysis and a systematic design methodology for a novel nonraster scan method based on a rosette pattern and demonstrate its application in video-rate atomic force microscopy. This pattern is traced when the lateral axes of a...

On the effect of local barrier height in scanning tunneling microscopy: Measurement methods and control implications.

The Review of scientific instruments

Tajaddodianfar F, Moheimani SOR, Owen J, Randall JN.
PMID: 29390696
Rev Sci Instrum. 2018 Jan;89(1):013701. doi: 10.1063/1.5003851.

A common cause of tip-sample crashes in a Scanning Tunneling Microscope (STM) operating in constant current mode is the poor performance of its feedback control system. We show that there is a direct link between the Local Barrier Height...

High-speed Lissajous-scan atomic force microscopy: scan pattern planning and control design issues.

The Review of scientific instruments

Bazaei A, Yong YK, Moheimani SO.
PMID: 22755628
Rev Sci Instrum. 2012 Jun;83(6):063701. doi: 10.1063/1.4725525.

Tracking of triangular or sawtooth waveforms is a major difficulty for achieving high-speed operation in many scanning applications such as scanning probe microscopy. Such non-smooth waveforms contain high order harmonics of the scan frequency that can excite mechanical resonant...
