We report on the successful growth of an isotopically enriched 28Si bulk single crystal of the size approximately 4 mm in diameter and approximately 50 mm in length. The isotopic enrichment of 28Si (99.924 at%), 29Si (0.073 at%), and 30Si (0.003 at%) has been determined by secondary-ion-mass spectroscopy (SIMS). The crystal is entirely p-type with the room temperature free-hole concentration approximately 5×1017 cm-3. The majority impurity is found to be aluminum which can be removed easily in the future zone purification process.
