Dr. Sudhakar is a distinguished leader in the field who has received world-wide recognition for his groundbreaking contributions. He has a prolific publication record and has authored about 38 technical research publications in major high impact journals and international conference proceedings related to Materials Science and Engineering. Dr. Sudhakar's prime research interests are focused on the applications of transition metal oxide based Nanostructured Magnetic Materials, which are very useful for making ultra sensitive Infrared Detectors for night visionary devices, Spintronic devices that exploit both charge as well as the spin of the electron. This paves way and facilitates the realization of a host of new electronic devices and gadgets with ever - decreasing dimensions.
Some of the various classes of oxide materials that were probed intensely by Dr. Sudhakar include (i) High Temperature Superconductors (High T c ), (ii) Carbon based Fullerenes (C60's), (iii) Colossal Magnetoresistive Materials (CMR), (iv) Diluted Magnetic Semiconductors (DMS) (v) Gold Nanodots and (vi) Cobalt based Nanostructures and Multilayers. He had already made many important scientific contributions in all the above areas of futuristic oxide based materials. For instance, his fundamental work on LaSrCuO and YBaCuO, High T c superconductors, where he extracted the critical exponents, based upon the superconducting fluctuations of the conductivity, has received a high number of citations and is considered major advancement in understanding the highly complex mechanisms of superconductivity.
He also has a deep insight of structure-property correlation of ultra thin films, Nanodots and heterostructured materials. This is very essential to transform the laboratory ideas to manufacturing stage in the current era that is witnessing an avalanche of smart electronic gadgets and devices. More technically, his innovative and pioneering work, which was presented in the recently concluded prestigious MRS Fall Meeting (Boston, Nov.26-30, 2007), on transition metal (Nickel, Cobalt and Copper) doped Magnesium Oxide single crystals and thin films is key to open new vistas in device fabrication and realization. These materials, on which Dr. Sudhakar has been working, facilitate a giant transition from the conventional electronics to an altogether new regime, known as Spintronics. The process of continuous miniaturization of a given chip where the economic growth of any major chip-manufacturing companies, such as Intel or Micron, relies heavily on the size and speed of a device. These include MRAM's and Spin Valves, to name a few, that exploit the spin of an electron instead of charge to pave way for Tera bits per square inch technology. Typical Millipede chip uses silicon micromachining techniques to precisely move a silicon substrate coated with a thin-film polymer beneath an array of 1,024 parallel activated 20-nanometer read/write heads, which were also etched from silicon. However, further breakthroughs are required replacing the current Si-based chip integration with smarter new materials in order to achieve ultra fast, ultra high densities of the order of 1-10 tera bit per square inch. The next generation non-volatile devices, such as phase change memory (PRAM), Nano Floating Gate Memory (NFGM), Polymer Memory (PoRAM) and Insulator Resistance Change Memory (ReRAM), are slated to take over the challenges . This indeed is a highly interesting and important subject area from the point of fabricating sensitive and ultra fast detection devices useful for U.S. Army and Air Force applications. Dr. Sudhakar's recent experimental findings are unique and highly significant. They are a direct consequence of his exceptional skills and superior expertise in both Experimental Condensed Matter Physics and Materials Science.
He has distinguished himself as a highly productive researcher, who has not only produced important technology for the development of next generation Nanomaterials, but also has produced innovative ideas with cascading effects in many scientific fields and technology and the economy at large.
He has been elected as a member to several important research societies, such as TMS (The Minerals, Metals & Materials Society) and MRS (Materials Research Society), that actively pursue and encourage the nanomaterials research. Dr. Sudhakar was also appointed as the Secretary/Vice Chaiman of the 'Superconducting and Magnetic Materials' Committee of TMS, during TMS Annual Meeting (Orlando , Feb.25-Mar.1, 2007). Dr. Sudhakar also Chaired a session for the International Symposium on ‘Wide Band-Gap Semiconductor Nanostructures' and received honorary recognition. Dr. Sudhakar is uniquely suited to continue his seminal research on next generation materials and is a leading Nanomaterials Scientist in the field who also has gained the respect of his peers on an international level. His extraordinary ability and path breaking ideas are critical to the fields of Nanoelectronics.
