A tip of this material is scanned over a sample and read out with ODMR in extremely sensitive vector magnetometers. The 2012 Ig Nobel Peace Prize was awarded for converting old Russian ammunition into this material by blowing up a TNT/RDX mixture. Room-temperature qubits can be implemented using the robust spin states of this material’s NV-centers. A high-pressure experimental (15[1])device places a sample between two tips of this material (15[1])in an (*) “anvil cell.” (10[1])Besides CVD, the other major method of manufacturing this material synthetically (10[1])is the high-pressure high-temperature method. This material’s face-centered cubic lattice (10[1])is shared by elemental silicon. For 10 points, many industrial cutting edges and drill tips are made of the synthetic variant of what very hard allotrope of carbon? ■END■
