University of Alabama at Birmingham researchers will use pressures greater than those found at the center of the Earth to potentially create as yet unknown new materials. In the natural world, su...
Researchers Integrate Diamond/Boron Nitride Crystalline Layers for Use in High-Power Devices
Researchers Integrate Diamond/Boron Nitride Crystalline Layers High-Power Devices
2016/5/10
We have created a new state of BN (named Q-BN) through rapid melting and super undercooling and quenching by using nanosecond laser pulses. Phase pure c-BN is formed either by direct quenching of supe...

boron-doped diamond superconductivity Raman spectroscopy isotope effect
2009/1/28
Superconducting boron-doped diamond samples were synthesized with isotopes of 10B, 11B,
13C and 12C. We claim the presence of a carbon isotope effect on the superconducting
transition temperature, w...
