Abstract:
Disclosed is a measurement method of a scanning probe microscope based upon a measurement method of a scanning probe microscope for observing a shape and an optical property of a sample by exciting near-field light, scanning relative positions of the near-field light and the sample and detecting scattered light by the sample of the near-field light and having a characteristic that the near-field light is modulated to periodically vary the relative positions of the near-field light and the sample and that a frequency of modulation applied to the near-field light and an interference signal generated at a frequency for varying the relative positions of the near-field light and the sample are selectively extracted.
Abstract:
A method of obtaining PINEM images includes providing femtosecond optical pulse, generating electron pulses, and directing the electron pulses towards a sample. The method also includes overlapping the femtosecond optical pulses and the electron pulses spatially and temporally at the sample and transferring energy from the femtosecond optical pulses to the electron pulses. The method further includes detecting electron pulses having an energy greater than a zero loss value, providing imaging in space and time.
Abstract:
A system and method for optically imaging a sample. The method and system uses a controlled scatterer of light positioned in the near field of a sample. The extinguished power from an incident field, which illuminates both the sample and the controlled scatterer, is then measured as a function of the controlled scatterer position and is used to mathematically reconstruct an image of the sample.

Abstract:
An infrared light condensing apparatus is provided that permits an infrared light of several tens microns in wavelength to be focused efficiently at a microfine area of submicron or less and also a near-field from a microfine area of submicron or less to be taken out efficiently and at the same time permits a scanning image to be obtained. It includes a solid immersion lens (2) made of a medium of high index of refraction for coupling an incident light (8) or an outgoing light (9) to an antenna efficiently, a measured specimen (6) disposed on a base plane (3) of the solid immersion lens (2), the antenna (4), e.g., a planar dipole antenna (14) or a planar slot antenna (16), that is disposed away from the base plane (3) at a distance that is ¼ of an effective wavelength of the light for causing the light to geometrically resonate therewith, a probe (4b) in the form of a rod-like conductor having a sharply point end projecting from the antenna (4), and a position control means such as a triaxial XYZ mechanical stage (23) for controlling the position of the probe (4b) with the intermediary of a cantilever (5). Coupling the incident light (8) or the outgoing light (9) to the antenna (4) is made through the high dielectric constant medium side and an antenna capable of bringing about geometrical resonance is used to enhance the efficiency.
Abstract:
A probe for non-destructive determination of complex permittivity of a material and for near field optical microscopy is based on a balanced multi-conductor transmission line structure created on a dielectric substrate member which confines the probing field within a sharply defined sampling volume in the material under study. A method for manufacturing dielectric support member based probes includes anisotropically depositing a 50-100 Å thick underlayer of Cr, Ni, W or Ta onto the dielectric support member, anisotropically depositing conductive material onto the Cr, Ni, W or Ta underlayer, and removing the unwanted conductive material at the sides of the dielectric support member to electrically isolate the created conductive strips.
Abstract:
A device is provided. The device includes a base, and a reservoir disposed in the base. The reservoir is defined by a cladding and the base, and has an opening with a largest dimension of about 200 nm or less, more preferably 100 nm or less, and most preferably 60 nm or less. A material may be disposed within the reservoir. The base may be attached to a position control apparatus that may control the position of the base with an accuracy on the order of nanometers. The position control apparatus may include an atomic force microsope and/or a near field scanning optical microscope. The base may also be coupled to an energy application apparatus that may apply energy to the material. The device may be used to deposit material onto a substrate with a very high resolution, on the order of a few molecules across. The device may also be used to remove material from a substrate with a very high resolution by transmitting energy through the base. A device used for such removal may or may not include a reservoir.
