Experts Discuss Heterostructure Engineering for Quantum Materials & Devices

Roorkee: Leading international and national experts from the field of quantum matters discussed the role of emergent electromagnetic phenomena in designer thin films, heterostructures, and hybrids of quantum materials at the National Conference on Quantum Matter Heterostructures (QMH)-II.

“Quantum Materials are enticing for science and technology, and activities are being initiated with state-of-the-art facilities to synthesise new kinds of quantum devices for technological application. Combining the power and possibilities of heterostructure engineering with the collective and emergent properties of quantum materials, quantum-matter heterostructures open a new arena of solid-state physics,” said Prof. Amitava Patra, Director, Institute of Nano Science and Technology (INST), Mohali, while addressing the inaugural session.

 

Prof. Ajit Kumar Chaturvedi, Director IIT Roorkee, stressed on the importance of quantum materials, especially in electronic devices. “We cannot imagine any electronic device without the foundation laid by materials, starting from the basic p-n junction. The kind of devices that can be realised using heterostructures will depend on the imagination and innovation of experts ” he said at the conference jointly organized by the Institute of Nano Science and Technology (INST), Mohali, and Indian Institute of Technology Roorkee between February 18 to 20, 2021.

 

“In 2018, the office of PSA showed keen interest to bolster the material resources in India with particular emphasis to cater to the need of quantum technologies. This conference will serve as a platform to discuss the emergent trends in quantum matters and heterostructures to foster the collaboration on the topic of mutual interest,” Dr. SuvankarChakraverty, member of the organizing committee of the National Conference on Quantum Matter Heterostructures (QMH)-II pointed out.

 

Prof. R. Ramesh from the Department of Physics, University of California, Berkeley deliberated on ‘Observation of chiral, room temperature polar Skyrmions’ a phenomenon that occurs due to thermodynamics where he highlighted the work done by his team and discussed the challenges in quantum matters like converting spin to charge and charge to spin at his plenary talk. Prof. Masashi KAWASAKI from the Department of Applied Physics, University of Tokyo, spoke on ‘Electrons in ultra-clean ZnOheterostructures’ and presented an overview of the recent activities on oxide heterostructures based on Zinc Oxide (ZnO) carried out by his group. The talks were chaired by D. D. Sarma from Indian Institute of Science, Bengaluru, India. Dr. Vivek Malik, organizer from IIT Roorkee, had conducted the inaugural session.

 

On the third day of the conference, a special Prof. S. K. Joshi Memorial session was organized to discuss the contributions of Prof. Joshi and bulk materials relevant for Quantum Heterostructures.

 

Prof. T. V. Ramakrishnan, FRS and Padma Shri, chaired the session and informed the audience about the scientific contributions and achievements of Prof. Joshi. Prof. E. V. Sampathkumaran, Tata Institute of Fundamental Research, delivered a plenary talk on “Unexpected transport behavior of Gd alloys:1998 to 2020”. Prof. S. D. Mahanti, Michigan State University shed light on various aspects of personality of Prof. Joshi. Three invited technical talks were also delivered in the session by eminent scientists.

 

The conference organized by INST, Mohali, an autonomous institute of the Department of Science & Technology, Government of India in association with IIT, Roorkee, was attended by more than 250 invited speakers who will discuss the present status, limitations, perspectives, and challenges in the field of heterostructures of quantum materials and related devices over three days. On the third day of the conference, a special session dedicated to the memory of Professor S.K. Joshi is being organized to discuss bulk materials relevant for Quantum Heterostructures. Future plans and perspectives in the field of QMH will also be discussed on the same day.

 

The conference, which brings together experts from around the world to discuss research related to heterostructure engineering for quantum materials and devices, provides an unique opportunity to researchers working in the area of Quantum heterostructures related to quantum materials to be exposed to the latest R&D in the field.
