In a bolometer probe the resistor is used as a local heater and the fractional change in probe resistance is used to detect the temperature and/or the thermal conductance of the sample. [15] When the tip is placed in contact with the sample, heat flows from the tip to sample. As the probe is scanned, the amount of heat flow changes.
In one particular type of AFM, known as scanning thermal microscopy (SThM), the imaging probe is a sub-miniature temperature sensor, which may be a thermocouple or a resistance thermometer. [3]
Market research [5] and industry experts [6] confirm that NanoWorld today is the global market leader for AFM probes for scanning probe microscopy (SPM) and atomic force microscopy (AFM). NanoWorld's unique selling proposition is the consistent quality of its AFM probes which is essential for reproducible imaging by atomic force microscope .
Scanning Hall probe microscope (SHPM) is a variety of a scanning probe microscope which incorporates accurate sample approach and positioning of the scanning tunnelling microscope with a semiconductor Hall sensor. Developed in 1996 by Oral, Bending and Henini, [2] SHPM allows mapping the magnetic induction associated with a sample.
Scanning probe microscopy (SPM) is a branch of microscopy that forms images of surfaces using a physical probe that scans the specimen. SPM was founded in 1981, with the invention of the scanning tunneling microscope , an instrument for imaging surfaces at the atomic level.

The Philippines' antitrust agency said on Friday it will investigate allegations that its major telecoms firms abused their dominant market positions to make it difficult for a China-backed ...
A decade later, a patent on an optical near-field microscope was filed by Dieter Pohl, [12] followed in 1984 by the first paper that used visible radiation for near field scanning. [13] The near-field optical (NFO) microscope involved a sub-wavelength aperture at the apex of a metal coated sharply pointed transparent tip, and a feedback ...
