S. C. Jain

S. C. Jain is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand S. C. Jain rather than just read about it. In short: Suresh Chand Jain (5 December 1926 – 10 December 2009) was an Indian physicist and director of the Defence Research and Development Organization. Known for his research in solid state physics, Jain was an elected fellow of the Indian National Science Academy and National Academy of Sciences, India.

Key takeaways

  • S. C. Jain belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect S. C. Jain to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of S. C. Jain from memory before moving on to harder problems.

Reference excerpt

Suresh Chand Jain (5 December 1926 – 10 December 2009) was an Indian physicist and director of the Defence Research and Development Organization. Known for his research in solid state physics, Jain was an elected fellow of the Indian National Science Academy and National Academy of Sciences, India. In 1966, the Council of Scientific and Industrial Research, the apex agency of the Government of India for scientific research, awarded him the Shanti Swarup Bhatnagar Prize for Science and Technology, one of the highest Indian science awards for his contributions to physical sciences.

Biography

S. C. Jain, born on 5 December 1926 in Saharanpur in the Indian state of Uttar Pradesh, earned an MSc degree in physics in 1949 and followed it up with a PhD in solid state physics from Delhi University in 1955, carrying out his research at the National Physical Laboratory, Delhi under Kariamanickam Srinivasa Krishnan. Subsequently, he moved to the UK to take up the position of a faculty member at University of Leeds and worked there until 1958. On his return to India, he joined the Indian Institute of Technology, Delhi where he served as the head of the department of physics from 1965 to 1968 and as the dean of faculty of science from 1966 to 1969. Concurrently, he worked at his alma mater, the National Physical Laboratory, and held the position of a deputy director during 1965–69, and as the director of Solid State Physics Laboratory (SSPL) during the period 1969–74. While heading the SSPL, he also held the directorship of the Defence Research and Development Organization (DRDO). In between, he did visiting professor assignments at University of Illinois, Atomic Energy Research Establishment and Imperial College of London (1975–77). Jain died on 10 December 2009, at the age of 83.

Legacy During his doctoral studies, Jain assisted his mentor, K. S. Krishnan, the co-discoverer of the Raman Effect, on the thermal conductivity of solids. It was during this time, the duo developed a methodology for the measurement of thermal conductivity in solids at high temperatures which was published by them in an article, Thermionic Constants of Metals and Semiconductors. II. Metals of the First Transition Group in 1952 in Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences and later explained further by way of another article, Determination of thermal conductivities at high temperatures in British Journal of Applied Physics in 1954. The measurement protocol later came to be known as the "Jain-Krishnan Method". Polar crystals, thin films and semiconductor devices are some of the other areas he worked on, and he was credited with developing experimental techniques in these disciplines which are in use around the world. He also contributed to the development of electronic equipment for the military. His studies have been documented by way of a number of articles and he published four books viz. Recent advances in semiconductors: theory and technology, Nonmetallic crystals, Germanium-silicon strained layers and heterostructures, and Electronic absorption and internal and external vibrational data of atomic and molecular ions doped in alkali halide crystals. Jain was the director of the International Advanced School on Theory and Technology of Semiconductors, an Indian Institute of Technology Delhi (IIT Delhi) program held in April 1968. He chaired the international conference on science and technology of non-metallic crystals held at IIT Delhi in January 1969 and was associated with International Union of Pure and Applied Physics as a member of its solid state commission. He was also a member of the editorial boards of journals such as Radiation Effects and Defects in Solids, Crystal Lattice Defects and Amorphous Materials and Journal of Nonmetals and was a senior member of the Institute of Electrical and Electronics Engineers.

Awards and honors The Council of Scientific and Industrial Research awarded Jain the Shanti Swarup Bhatnagar Prize, one of the highest Indian science awards in 1966 and the Indian National Science Academy elected him as a fellow in 1979. He was also a fellow of the National Academy of Sciences, India, Physical Society of London, American Physical Society, Faraday Society and Institution of Electronics and Telecommunication Engineers.

Worked examples

Example 1 — a first encounter with S. C. Jain

Start with the simplest possible case. Write down what S. C. Jain claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to S. C. Jain before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about S. C. Jain ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of S. C. Jain

In research
S. C. Jain appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses S. C. Jain in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
S. C. Jain is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1926 births, 2009 deaths, 20th-century Indian physicists, so understanding it makes those chapters shorter.
In everyday life
Look for S. C. Jain outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
