Photocurrent near‐field microscopy of Schottky barriers
Journal of Microscopy, 1999We used a combination of internal photoemission and of near‐field optical microscopy (SNOM) to study the lateral variations in solid interface properties such as energy barriers and electron–hole recombination. In particular we investigated the fully formed Pt–GaP, Au–GaAs, Au–SiNx–GaAs and PtSi–Si Schottky barriers.

Differential Near-Field Scanning Optical Microscopy
Nano Letters, 2006We theoretically and experimentally illustrate a new apertured near-field scanning optical microscopy (NSOM) technique, termed differential NSOM (DNSOM). It involves scanning a relatively large (e.g., 0.3-2 mum wide) rectangular aperture (or a detector) in the near-field of an object and recording detected power as a function of the scanning position ...

Near-Field Microscopy Through a SiC Superlens
Science, 2006The wave nature of light limits the spatial resolution in classical microscopy to about half of the illumination wavelength. Recently, a new approach capable of achieving subwavelength spatial resolution, called superlensing, was invented, challenging the already established method of scanning near-field optical microscopy (SNOM).

Terahertz near-field microscopy
Optical Terahertz Science and Technology, 2005We present results on the spatial extent and origin of the near-field of a metal tip and the first measurement on a crystal of CsI using THz apertureless scanning near-field optical microscopy.

Scanning near-field optical microscopy
Current Opinion in Colloid & Interface Science, 1999Abstract Scanning near-field optical microscopy (SNOM) has become a widespread technique due to its promising ability of imaging with sub-micron resolution. Despite being developed over more than one decade, SNOM is still not a mature technique, which can be seen from the large number of recent publications describing instrumentational innovations ...

Journal of Russian Laser Research, 2006
Three techniques of optical near-field microscopy are considered. In one of them a probe in the form of a nanosphere interacts with a solid surface. The second technique is a probeless one based on the Brewster reflection of a laser beam from the surface of a non-absorptive dielectric in the presence of foreign atoms at it. The third technique is based

In the following, some of the basic considerations at the foundation of near field microscopy are presented [1, 2, 3, 4, 5]. Near field microscopy is a new form of microscopy which was first proposed in 1928 as a means of increasing microscope resolution over that available by traditional techniques of far field microscopes.

Scanning near-field microscopies
SPIE Proceedings, 1990Optical images whose resolution is not limited by diffraction can be created by recording the radiation from a point-like (subwavelength size) probe light source while raster scanning it across an object in immediate proximity. An imaging capability with resolution in the range from 1 to 50 nm has been demonstrated with various types of light sources ...

NEAR-FIELD MICROSCOPY: THROWING LIGHT ON THE NANOWORLD
Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2003Optical microscopy with nanoscale resolution, beyond that which is possible with conventional diffraction-limited microscopy, may be achieved by scanning a nanoantenna in close proximity to a sample surface. This review will first aim to provide an overview of the basic principles of this technique of scanning near-field optical microscopy (SNOM ...
