61Electron beam lithography — (often abbreviated as e beam lithography) is the practice of scanning a beam of electrons in a patterned fashion across a surface covered with a film (called the resist),cite book |last= McCord |first=M. A. |coauthors=M. J. Rooks |title=… …
62Kapitsa-Dirac effect — The Kapitsa Dirac effect is a quantum mechanical effect consisting in the diffraction of a well collimatedclarifyme particle beam (often an electron beam), by a standing wave of light. [ cite journal|title=The Kapitza Dirac… …
63Atomic force microscope — The atomic force microscope (AFM) or scanning force microscope (SFM) is a very high resolution type of scanning probe microscope, with demonstrated resolution of fractions of a nanometer, more than 1000 times better than the optical diffraction… …
64Smith-Purcell effect — The Smith Purcell effect was the precursor of the free electron laser (FEL). It was studied by Steve Smith, a graduate student under the guidance of Edward Purcell. In their experiment, they sent an energetic beam of electrons very closely… …
65Charles Taylor (physicist) — Charles Alfred Taylor (1922–2002) was a British physicist well known for his work in crystallography and his efforts to promote science to young audiences. Charles Taylor was born in Hull in 1922.[1] He began his degree in Queen Mary s College at …
66diffractiongrating — diffraction grating n. A usually glass or polished metal surface having a large number of very fine parallel grooves or slits and used to produce optical spectra by diffraction of reflected or transmitted light. * * * …
67bright-field microscopy — Optical microscopy, in which absorption to a great extent and diffraction to a minor extent give rise to the image, as opposed to phase contrast or interference methods of microscopy …
68Superlens — A superlens, super lens or perfect lens is a lens which uses metamaterials to go beyond the diffraction limit. The diffraction limit is an inherent limitation in conventional optical devices or lenses.[1] In 2000, a type of lens was proposed,… …
