3D Nano-Probes for Thermal Microscopy

Multifunctional hydrogel nano-probes for atomic force microscopy

Since the invention of the atomic force microscope (AFM) three decades ago, there have been numerous advances in its measurement capabilities. Curiously, throughout these developments, the fundamental nature of the force-sensing probe-the key actuating element-has remained largely unchanged. It is produced by long-established microfabrication etching strategies and typically composed of silicon...

Fabrication and Characterization of Nano Probes for Scanning Electrochemical Microscopy

Magnetic force microscopy using fabricated cobalt-coated carbon nanotubes probes

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 (...

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 ...
