TEHRAN (FNA)- Physicists used a scanning
tunneling microscope to create a minute transistor consisting of a single molecule and a small number of atoms.
High-tech highlights include clean rooms, where particle levels in the air are controlled, and a low-vibration, scanning
tunneling microscope facility.
The topics include the basic theory of the molecule-metal interface, scanning
tunneling microscope studies of the interfaces, X-ray standing waves and surfaces X-ray scattering studies of molecule-metal interfaces, the fundamental structure of organic solids and their interfaces by photoemission spectroscopy and related methods, and vibrational spectroscopies for future studies of the molecule-metal interface.
at about 1 degree Kelvin, they measured the magnetic orientation of the atom using the fine tip of a scanning
tunneling microscope.
A team carefully pointed the tip of a scanning
tunneling microscope, which can manipulate surfaces at atomic scales, toward a thin magnetic film.
Jamie Panas of Guinness World Records said Guinness certified the movie as "Smallest Stop-Motion Film." IBM used a remotely operated two-ton scanning
tunneling microscope at its lab in San Jose, California, to make the movie earlier this year.
To set up the tiny storage system, engineers used a scanning
tunneling microscope at temperatures near absolute zero.
This development--made possible with a low-temperature scanning
tunneling microscope at Tufts, one of only about 100 in the US--may be the first step toward a new class of devices that could be used in applications ranging from medicine to engineering.
