Abstract
We report on 11B and 13C NMR nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) study of a lightly boron-doped microdiamond. 11B NMR shows two components assigned to boron atoms substituting carbon and those located within the conducting regions, respectively. The latter component demonstrates exceptionally short spin-lattice relaxation time (T1 = 2.4 ms) characteristic of conductive compounds. The total content of localized paramagnetic defects is 24 ppm, among them 12 ppm are due to substitutional nitrogen defects (P1). The P1 content is found to be much smaller than that usually observed in conventional high pressure—high temperature (HPHT) diamonds.
