Meeting 2022 TMS Annual Meeting & Exhibition
Symposium Advances and Discoveries in Non-equilibrium Driven Nanomaterials and Thin Films
Presentation Title Extraordinary Properties of Q-carbon and Diamond Related Materials
Author(s) Jagdish Narayan
On-Site Speaker (Planned) Jagdish Narayan
Abstract Scope This talk summarizes the formation Q-carbon and Q-BN (new allotrope of carbon and BN) by nonequilibrium laser annealing, and electron and ion irradiations. The Q-phases provide an ideal platform to grow diamond and c-BN epitaxial thin heterostructures and coatings needed for next-generation solid state devices. The Q-phases are the harder than diamond as much as 60%. The Q-carbon is ferromagnetic in pure-form, and shows record high-temperature superconductivity upon doping with boron. The record hardness and superconductivity are interrelated through Debye frequency and electron-phonon interactions. Recently, we have discovered that Q-carbon is extremely resistant to radiation damage, involving atomic displacements. After ion irradiations (5 MeV Au ions), detailed studies show that atomic structure (HRTEM, HAADF) and bonding characteristics (EELS and Raman) of Q-carbon have remained essentially unchanged after 15dpa of radiation damage, which is equivalent to over twenty years of neutron damage in a conventional reactor.
