Narayan developed domain matching epitaxy (DME),[20][21] which involves matching of integral multiples of lattice planes, addressing the epitaxial growth of heterostructures across the misfit scale. Domain matching epitaxy led to the integration of oxides and III-nitrides on industrially relevant (100) Si and sapphire substrates.[21][22][23]

Jagdish Narayan[1] is an Indian-born American engineer. Since 2001, he has been the John C. C. Fan Family Distinguished Chair Professor in the Materials Science and Engineering Department at North Carolina State University. He is also the distinguished visiting scientist at Oak Ridge National Laboratory. Narayan has published above 500 high-impact journal articles, with his discoveries covered in over 40 US and international patents. He has conducted research on non-equilibrium laser processing of novel nanomaterials, including Q-carbon, Q-BN,[2] diamond and c-BN related materials. These research articles have received over 31,000 Google citations with h-index >85.[3] Narayan and his students discovered Q-carbon asa new allotrope, thereby finding a new route to fabricate diamond and related materials in ambient conditions, resulting in properties and applications ranging from high-temperature superconductivity in boron-doped Q-carbon[4] to hardness than diamond in Q-carbon to enhanced field-emission in Q-carbon[5] to nitrogen-doped nanodiamonds[6] for quantum computing, nanosensing and solid-state devices. While he and his students have published many papers on Q-carbon, there are few reports of this work being validated by others.

Early life and education

Narayan moved to the United States in 1969 from India.[7] After completion of his bachelor's degree (with distinction and honors) from IIT Kanpur, India,[citation needed] he joined UC Berkeley in 1969 and finished his MS (1970) and PhD (1971) in materials science and engineering.

Professional career

After finishing his PhD, Narayan served as a research metallurgist at the Lawrence Berkeley National Laboratory[citation needed] from 1971 to 1972. He later joined Oak Ridge National Laboratory, where he retired as a senior scientist and group leader of the Thin Films and Electron Microscopy Group (1972–84). In 1984, he joined the North Carolina State University as NC Microelectronics Professor and director of the Microelectronics Center of North Carolina. He was appointed as a Distinguished University Professor in 1989. In 2001, he was appointed as the John C. Fan Distinguished Chair Professor. He was also the director of the Division of Materials Research (DMR) of US National Foundation (1990–92). He received the NSF's Distinguished Service Award.[8] He has mentored over 80 PhD students.

Research

He has conducted research on nanosecond laser annealing, Narayan has pioneered developments in laser-solid interactions and transient thermal processing of nanomaterials and epitaxial thin films. He has contributed t o the fields of pulsed laser deposition technique and epitaxial growth of thin-films.

Narayan developed domain matching epitaxy (DME),[20][21] which involves matching of integral multiples of lattice planes, addressing the epitaxial growth of heterostructures across the misfit scale. Domain matching epitaxy led to the integration of oxides and III-nitrides on industrially relevant (100) Si and sapphire substrates.[21][22][23]

His research group at NC State focuses on the controlled fabrication and processing of novel nanomaterials utilizing the pulsed laser deposition using PLD and Laser MBE units, thermal processing of materials using nanosecond laser annealing and generating new epitaxial heterostructures across the misfit scale, utilizing domain matching epitaxy.
