Academic Report2005-2011

Indian Institute of Technology Delhi is one of the fifteen Institutes of Technology created as centers of excellence

for training, research and development in science, engineering and technology in India. Established as College of

Engineering in 1961, the institute was later declared an Institution of National Importance under the “Institutes of

Technology (Amendment) Act, 1963” and was renamed “Indian Institute of Technology Delhi”. It was then accorded

the status of a deemed university with powers to decide its own academic policy, to conduct its own examinations,

and to award its own degrees.

HRH Prince Philip, the Duke of Edinburgh, laid the foundation stone of the Institute on January 27, 1959. The

academic activities of the Institute started on August 16, 1961 with the arrival of first batch of students on campus

and the formal inauguration of the teaching activity was done by Prof. Humayun Kabir, the then Union Minister

for Scientific Research and Cultural Affairs on August 17, 1961. The main academic complex of the Institute was

opened by Dr. Zakir Hussain, the then President of India on March 2, 1968. The Institute celebrated its silver Jubilee

during 1985-86 and the Silver Jubilee Convocation was addressed by Shri Rajiv Gandhi, the then Prime Minister

on December 19, 1985. The Institute has made a notable mark in higher technical education and research. It has

been ranked very high among national and international institutions of higher learning. The Institute is celebrating

its Golden Jubilee Year during 2010-2011. The Golden Jubilee Year was inaugurated by the Hon’ble President,

Smt. Pritibha Devisingh Patil on August 16, 2010.

Welcome note from the Head of the DepartmentThe Department of Physics was one of the very first few departments at IIT Delhi, which was established

in 1961, and has earned the reputation of being one of the very popular physics departments in the country and is well known abroad. Legacy of our department’s distinctive strength lies in its pursuit for interdisciplinary research – both theoretical and experimental, which would fall within the category of more towards applied physics though we do have few faculty experts, who pursue pure physics.

Ours is one of the large academic departments at the Institute. The department offers several academic programmes at the Masters’ levels and a B.Tech. Programme. These are M.Sc. Physics, M. Tech. in Applied Optics, M. Tech. in Solid State Materials, interdisciplinary M. Tech. (jointly with the Electrical Engineering Department) in Optoelectronics and Optical Communication, and B. Tech. in Engineering Physics. Our current Ph.D. student strength is over 140; at the just concluded annual convocation of the institute in August 2011, 23 students from our department have been awarded Ph.D. degree. At this time we have 38 serving faculty members in the department and 22 technical and support staff.

Our faculty, Ph.D. students and research project staff carry out fundamental and advanced research on contemporary topics in science disciplines like material and condensed matter physics, optics and photonics, plasma physics, and theory and computational physics. Our faculty is involved with emerging and much talked about topics like nano science and technology, laser induced shape and size manipulation of nanoparticles, surface nanostructuring by pulsed laser interference lithography, semiconductor nanowires, spintronics, quantum condensed matter physics, non-equilibrium statistical mechanics, density functional theory for band structure, magnetic materials, multiferroics, Heusler alloys, nanophotonics, microstructured optical fibers, photonic crystals, plasmonics, optical fibers, integrated optics, guided wave optics-based quantum information and encryption, attosecond optics, optical phase singularity, biometrics, hadrons in hot and dense matter and so on. Active research on such contemporary topics helps in frequent updating of our syllabi and also in offering of elective course modules on emerging topics under the category of special topic courses. The courses are designed and taught by the faculty, who have excellent track record in the above-mentioned research topics. Major project dissertations that are offered to final year undergraduate and post graduate students allow their involvement and exposure to the ongoing advanced research in the department.

Over the years, our physics faculty has earned several distinguished national and international awards/fellowships such as SS Bhatnagar award of CSIR (India), International Commission of Optics’s Galileo Galilei Award, MRSI medal, OSA The Optical Society (USA) Fellowship, distinguished foreign membership of Royal Norwegian Academy of Science and Letters (Norway), fellowships of the national academies in India namely, Indian National Science Academy (New Delhi), National Academy of Science India (Allahabad), Indian Academy of Science (Bengaluru), and Indian National Academy of Engineers (New Delhi), UGC national awards and so on. Our faculty also receives honors as conference chair/ co-chair, technical session chair at major international conferences, plenary and invited speakers at national/international conferences, members of editorial advisory boards of international journals, chairs/members of major committees/initiatives of the Government of India on thrust areas of research from time to time.

In the last 6 years, the department has been awarded more than Rs. 520 million worth of sponsored research projects by various government and international agencies. Several members of our faculty are deeply involved in international network of collaborative research and in recent years have attracted substantial funding from government and reputed research organizations including corporate world from the western countries.

Our department is well-equipped with excellent laboratory and computational infrastructures and also manages several advanced analytical instruments as central facilities required in contemporary research. In order to fuel the future of our bright students through quality training and education, our faculty continues to strive to achieve greater heights in contemporary research.This helps in ensuring that our department becomes an even more inspiring, welcoming, and motivating work place for attracting both the brightest students and outstanding new faculty.

On going from nitrogen to hydrogen gas, the sensor responds due to changes in the electrical properties on PdH formation and about 10% expansion in the volume of the particles. A sharp pulse (sharp increase followed by a sudden decrease) in current

The data for theNi57Mn21Al22 (x = 5) sample imply that the crossover from semiconducting to metallicbehaviour of the resistivity could be brought about by magnetic ordering rather than by themartensitic transformation. Fig. B shows TEM dark and bright field images andcorresponding selected area electron diffraction (SAED) patterns tilted with respect to the[100]B2 matrix zone for x = 5 sample.
