USE OF CHARACTERISTIC X RAYS TO MONITOR ANNEALING OF ION-IMPLANTED DIAMOND

Abstract
Bombardment of aligned type‐IIa diamond substrates with 80‐keV protons and simultaneous detection of the resulting characteristic carbon K x rays has revealed excellent channeling structure. This technique has been used to monitor the crystallinity of a surface implanted with P31+ ions. Crystallinity was destroyed by P31+ does of the order of 1014/cm2. Vacuum annealing at 950°C restored the diamond cubic crystal structure.
