Scanning probe lithography[1] (SPL) describes a set of nanolithographic methods to pattern material on the nanoscale using scanning probes. It is a direct-write, mask-less approach which bypasses the diffraction limit and can reach resolutions below 10 nm. [2] It is considered an alternative lithographic technology often used in academic and ...
Dip pen nanolithography (DPN) is a scanning probe lithography technique where an atomic force microscope (AFM) tip is used to directly create patterns on a substrate. [1] It can be done on a range of substances with a variety of inks. A common example of this technique is exemplified by the use of alkane thiolates to imprint onto a gold surface ...
Technology portal. v. t. e. 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 first successful scanning tunneling ...
Bottom image shows atomic model (colors: grey, carbon; white, hydrogen; red, oxygen; blue, nitrogen). [1] Non-contact atomic force microscopy (nc-AFM), also known as dynamic force microscopy (DFM), is a mode of atomic force microscopy, which itself is a type of scanning probe microscopy. In nc-AFM a sharp probe is moved close (order of ...
Thermochemical nanolithography ( TCNL) or thermochemical scanning probe lithography ( tc-SPL) is a scanning probe microscopy -based nanolithography technique which triggers thermally activated chemical reactions to change the chemical functionality or the phase of surfaces. Chemical changes can be written very quickly through rapid probe ...
The name Scanning Capacitance Microscopy was first used to describe a quality control tool for the RCA/CED (Capacitance Electronic Disc), [1] a video disk technology that was a predecessor of the DVD. It has since been adapted for use in combination with scanned probe microscopes for measuring other systems and materials with semiconductor ...
A new type of lens using multiple scattering of light allowed to improve the resolution to about 100 nm. Several new microscopy techniques with a sub-nanometer resolution have been developed in the last several decades, such as electron microscopy (SEM and TEM) and scanning probe microscopy (NSOM, STM and AFM). SPM differs from other techniques ...
A voltage pulse applied between the AFM tip and the scanned surface yields to the formation of a liquid meniscus that confines a nanometric oxidation reaction. Local oxidation nanolithography ( LON) is a tip-based nanofabrication method. It is based on the spatial confinement on an oxidation reaction under the sharp tip of an atomic force ...
