Phosphorus Spin Coherence Times in Silicon at Very Low Temperatures

Phosphorus donor spin coherence in isotopically pure 28 silicon is measured at very low temperatures using pulsed electron spin resonance. The isolated spin T2 varies unexpectedly with phosphorus concentration

Pulsed ESR Measurement of Coherence Times in Si:P at Very Low Temperatures

A purpose built millikelvin pulsed x-band ESR system is used to measure spin decoherence times of phosphorus donor spins in 99.92% isotopically pure 28 silicon. The isolated P spin T2 is estimated at 260 (50) ms at 4.2 K and 330 (100) ms at 0.9 K.
