He invented the field ion microscope in 1955 after a year of tinkering with the design.rnrn“It was a sticky day in August that I became the first person to see an atom,” he said of his research. Mai 1977 in Washington, USA) war ein deutsch-amerikanischer Physiker. Among them are the Achievement Award of the Instrument Society of America (1960), the prestigious John Scott Medal presented by the City of Philadelphia (1970), and the American Physical Societys Davisson-Germer Prize (1972).

Im Anschluss daran erhielten Forscher viele weitere Erkenntnisse zu atomaren Prozessen auf Festkörper-Oberflächen. Forgot user … Erwin W. Mueller is Co-Founder at nPoint, Inc. View Erwin W. Mueller’s professional profile on Relationship Science, the database of decision makers. Similar to the field emission microscope, the field ion microscope consists of a sample in the shape of a pointed tip and a fluorescent screen, but unlike the other device, requires the presence of an imaging gas, such as hydrogen or helium, in a vacuum chamber before an electric field is applied to the tip, which is also located in the chamber. Müllers first major contribution to optics, the development of field emission microscopy, was made while he was still a graduate student working at Siemens, in 1936. Atoms of the gas adsorbed on the tip once positive voltage is applied are ionized and are repelled towards the fluorescent screen, effectively imaging the surface of the tip. This measurement can then be used to determine the mass of particular atoms, providing a highly useful means of compositional analysis. In 1976, Müller was also to receive the National Medal of Science, but due to a postponement of the ceremony, his daughter, Jutta, was obliged to accept it for him posthumously from President Jimmy Carter on November 22, 1977. https://en.wikipedia.org/w/index.php?title=Erwin_Mueller&oldid=909471935, Creative Commons Attribution-ShareAlike License, This page was last edited on 5 August 2019, at 17:17. Along with Müllers other inventions, the atom probe field ion microscope represented a significant advance in the field of materials science. Its products include piezo stages & scanners, nanopositioner electronics and nanopositioner software. In 1967, Müller invented yet another important scientific instrument, which he referred to as an atom probe, but later came to be more widely known as the atom probe field ion microscope. Here he developed the field ion microscope which, due to its resolution of 0.25 nm, was the first instrument used to observe atoms. Log in User name.

In his seven-season (1966–1973) NBA career, he also played for the Los Angeles Lakers, Seattle SuperSonics, and Detroit Pistons and scored 3,248 total points. However his tenure in Chicago would not last through the season. adshelp[at]cfa.harvard.edu The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Agreement NNX16AC86A Former Chief Technology Officer at nPoint, Inc.

Müller worked at the Siemens Research Laboratory, where he invented the field emission microscope in 1936 that allowed resolutions of 2 nanometers. Dubbed the field ion microscope, this Müller invention, with a magnification of 1,000,000 or more and a resolution of 0.25 nanometers, made it possible for the first time to obtain clear images of individual atoms and their arrangement on the surface of a sample.
