چکیده مقاله:

Magnetic force microscope ( MFM ) is a powerful technique for mapping the magnetic force gradient above the sample surface. Herein, single-wall carbon nanotubes (SWCNT) were used to fabricate MFM probe by dielectrophoresis method which is a reproducible and cost-effective technique. The effect of induced voltage on the deposition manner of carbon nanotubes (CNT) on the atomic force microscope ( AFM ) tip was investigated . The optimum voltage and frequency of SWCNT solution are obtained as 13 volts and 2 MHz, respectively. After coating theas-prepared CNT tips with a layer of cobalt,it can be used to obtain high resolution MFM images.

Scanning thermal microscopy of carbon nanotubes using batch-fabricated probes

We have designed and batch-fabricated thin-film thermocouple cantilever probes for scanning thermal microscopy ~SThM!. Here, we report the use of these probes for imaging the phonon temperature distribution of electrically heated carbon-nanotube ~CN! circuits. The SThM images reveal possible heat dissipation mechanisms in CN circuits. The experiments also demonstrate that heat flow through the ...

Lateral force microscopy of multiwalled carbon nanotubes.

Carbon nanotubes are usually imaged with the atomic force microscope (AFM) in non-contact mode. However, in many applications, such as mechanical manipulation or elasticity measurements, contact mode is used. The forces affecting the nanotube are then considerable and not fully understood. In this work lateral forces were measured during contact mode imaging with an AFM across a carbon nanotube...

Mechanics and Vibrations of Carbon Nanotube Atomic Force Microscopy Probes

Single and multi-walled carbon nanotubes (CNT) have been described as ideal tips for atomic force microscope (AFM) microcantilevers. They offer high spatial resolution, excellent wear resistance, the ability to image high aspect ratio semiconductor trenches, and possess a low bending stiffness which allows imaging of soft biomolecules with reduced contact forces. The objective of the current re...

Tuning electronic transport in cobalt-filled carbon nanotubes using magnetic fields.

Metal-filled and decorated carbon nanotubes represent a class of quasi one-dimensional hybrid systems with enormous potential for applications in nanoelectronics and spintronics. Here we show that is possible to control the electrical conduction in ferromagnetic metal-filled carbon nanotubes by means of external magnetic fields, suggesting specific dimensionality-dependent conduction regimes. B...

Nanopatterning on silicon surface using atomic force microscopy with diamond-like carbon (DLC)-coated Si probe

Atomic force microscope (AFM) equipped with diamond-like carbon (DLC)-coated Si probe has been used for scratch nanolithography on Si surfaces. The effect of scratch direction, applied tip force, scratch speed, and number of scratches on the size of the scratched geometry has been investigated. The size of the groove differs with scratch direction, which increases with the applied tip force and...
