American Physicist Earns Swedish Honor
Charles Fadley, a physics professor at UC Davis (Davis, California) has been elected as a foreign member of the Royal Society of Sciences at Uppsala, Sweden.
Charles Fadley, a distinguished professor of physics at UC Davis (Davis, California), has been elected into the Royal Society of Sciences at Uppsala. Founded in 1710, this prestigious Swedish institution has counted as members some of the world’s most renowned scientists, including Anders Celsius, Michael Faraday, and Charles Darwin.
Fadley is widely regarded as one of the foremost practitioners of photoelectron spectroscopy, a technique used for studying the composition and electronic state of a material using X-ray beams to excite electrons and a spectrometer to measure their energies. In recent years he has been a leader in the development of methods for studying very thin “nanolayers” of materials buried below surfaces, work that is integral to the development of next-generation computers, memory storage devices and other applications in the emerging field of nanotechnology.
The Uppsala society limits its membership to some 130 Swedish and 100 foreign members, who are elected for life. Fadley’s election brings to 14 the number of U.S.-based scientists in the society.
Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
