Last updated

Leonard Cecil Feldman (born New York City, 8 June 1939) is an American materials physicist.

He gained his B.A. degree in 1961 from Drew University and his Ph.D. from Rutgers University in 1967. He then joined AT&T Bell Laboratories, working on semiconductor materials physics. In 1996 he assumed the position of Stevenson Professor of Physics at Vanderbilt University and Distinguished Visiting Scientist at Oak Ridge National Laboratory. [1] [2]

His researches have focussed the use of ion beams for the study and modification of solids, studying the surface structure of solids, mostly semiconductors, at the monolayer level. His current interest concerns the effect of ion beam on nanostructures and organic materials.

He was named Fellow of the Institute of Electrical and Electronics Engineers (IEEE) in 2016 "for contributions to semiconductor-dielectric interfaces for MOS technologies". [3]

Ion implantation is a low-temperature process by which ions of one element are accelerated into a solid target, thereby changing the physical, chemical, or electrical properties of the target. Ion implantation is used in semiconductor device fabrication and in metal finishing, as well as in materials science research. The ions can alter the elemental composition of the target if they stop and remain in the target. Ion implantation also causes chemical and physical changes when the ions impinge on the target at high energy. The crystal structure of the target can be damaged or even destroyed by the energetic collision cascades, and ions of sufficiently high energy can cause nuclear transmutation.

Eli Yablonovitch is an American physicist and engineer who, along with Sajeev John, founded the field of photonic crystals in 1987. He and his team were the first to create a 3-dimensional structure that exhibited a full photonic bandgap, which has been named Yablonovite. In addition to pioneering photonic crystals, he was the first to recognize that a strained quantum-well laser has a significantly reduced threshold current compared to its unstrained counterpart. This is now employed in the majority of semiconductor lasers fabricated throughout the world. His seminal paper reporting inhibited spontaneous emission in photonic crystals is among the most highly cited papers in physics and engineering.

John Northrop Shive was an American physicist and inventor. He made notable contributions in electronic engineering and solid-state physics during the early days of transistor development at Bell Laboratories. In particular, he produced experimental evidence that holes could diffuse through bulk germanium, and not just along the surface as previously thought. This paved the way from Bardeen and Brattain's point-contact transistor to Shockley's more-robust junction transistor. Shive is best known for inventing the phototransistor in 1948, and for the Shive wave machine in 1959.

Ady Hershcovitch is a plasma physicist best known for his 1995 invention, the plasma window, which was later patented.. In the plasma window, a plasma separates air from a vacuum by preventing the air from rushing into the vacuum. This scientific development can facilitate non-vacuum ion material modification, manufacturing of superalloys, and high-quality non-vacuum electron-beam welding. The device has been compared to the force field in the Star Trek TV series. He is well known for his work in plasma physics at Brookhaven National Laboratory. He has over 80 publications and 15 patents.
