Abstract: Various examples are provided related to Q-silicon, Q-carbon and combinations thereof, and synthesis, properties and applications of Q-silicon and Q-carbon. In one example, a method includes forming a layer of amorphous silicon; melting at least a portion of the layer of amorphous silicon in an undercooled state; and forming Q-silicon by quenching the melted amorphous silicon from the undercooled state. In another example, a Q-silicon includes a random arrangement of tetrahedra, the tetrahedra including dangling bonds, unpaired spins or both. The atomic structure of the Q-silicon is based upon time in an undercooled state before quenching. In another example, a battery anode includes Q-silicon mixed with a polyvinylidene difluoride (PVDF) binder, the Q-silicon including a random arrangement of tetrahedra, the tetrahedra comprising dangling bonds, unpaired spins or both. The battery anode can include Q-carbon and Q-silicon mixed with the PVDF binder.

Abstract: Using processes disclosed herein, materials and structures are created and used. For example, processes can include melting boron nitride or amorphous carbon into an undercooled state followed by quenching. Exemplary new materials disclosed herein can be ferromagnetic and/or harder than diamond. Materials disclosed herein may include dopants in concentrations exceeding thermodynamic solubility limits. A novel phase of solid carbon has structure different than diamond and graphite.
