Abstract

We found that nuclear-spin decoherence is suppressed by applying inversion pulses such as alternating phase Carr-Purcell (APCP) and Carr-Purcell-Meiboom-Gill (CPMG) sequences in silicon and GaAs. The decoherence time reaches ∼ 1.3 s by applying inversion pulses, which is ∼ 200 times as long as the characteristic decay time obtained from the Hahn echo sequence (∼ 6 ms) in silicon.
