Dec. 2005 -- By Jamie Beckett

Alexandre "Alex" Bratkovski, a researcher working in the area of nanoscience and nanoelectronics, has been named a 2005 fellow of American Physical Society, an honor reserved for no more than half of one percent of APS membership.

Bratkovski (whose name is also spelled Bratkovsky) was honored for his contributions to the theory of magnetoresistance and spin injection and design of electronic and spintronic nanodevices which contributed to the development of a new type of non-volatile magnetoresistance memory devices. Bratkovski continues his work on quantum transport and spintronics, and is also working on ferroelectric nanostructures, sensors and optical metamaterials.

The APS Fellowship Program recognizes members who have made advances in knowledge through original research and publication or made significant and innovative contributions in the application of physics to science and technology. HP Labs Senior Fellow Bernardo Huberman is also an APS Fellow.

Bratkovski joined HP Labs in 1996 when the lab began its explorations into semiconductor nanostructures and nanoelectronics – work that has since expanded into molecular-size electronics, spintronics, ferroelectric nanostructures and optical metamaterials as a part of the Quantum Science Research group. In particular, his research has focused on transport and physical properties of systems of nanometer and molecular size, spin-dependent tunneling, theory of colossal magnetoresistance in doped manganites and superconductivity in cuprates, ferroelectric thin films and nanostructures, switching and domain pattern formation.

Immediately before joining HP, Bratkovski was a research in Oxford University's Department of Materials. From 1990 to 1993, he was a research fellow at Cambridge University's Interdisciplinary Research Centre in Superconductivity/Cavendish Laboratory. Prior to that, he was a senior research scientist at Kurchatov Institute, which is a premier Russian research institute in the areas of thermonuclear fusion, molecular, nuclear, and solid state physics, and superconductivity. HP Labs has recently seeded a new generation data center at Kurchatov Institute.

Bratkovski is a member of the American Physical Society and an affiliate member of Institute of Physics, UK. Since 1999, he has been a visiting professor at the Department of Physics, Loughborough University of Technology, UK.
Bratkovski has been an invited speaker at numerous conferences, including the Centennial (1999) March meeting of the American Physical Society. He also co-organized a tutorial session of APS on molecular quantum dots (2003), and several conferences and meetings related to nanotechnology. He has authored over 100 papers in refereed journals, including three review articles, and he holds 14 U.S. patents.

Members of the Quantum Science Research group have been honored repeatedly in recent years, most recently as one of the Scientific American 50 – the magazine's prestigious annual list recognizing outstanding acts of leadership in science and technology from the past year.
