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.
Claims12
A method comprising:
- melting boron nitride at a temperature no greater than about 2800 K by a laser pulse in an environment at ambient temperature and pressure;
- and
- quenching the melted boron nitride to create a form of boron nitride different than that of the melted boron nitride.
