Intermediate spin pair relaxation through modulation of isotropic hyperfine interaction in frequency-swept spin-dependent recombination in 4H-SiC

February 7, 2022
Author(s)
James Ashton, Brian Manning, Stephen Moxim, Fedor Sharov, Patrick Lenahan, Jason Ryan
Electrically detected magnetic resonance (EDMR) measurements have been extended to sub-mT measurements through utilization of frequency sweeping of the oscillating magnetic field, where conventional electron paramagnetic resonance-based measurements

Detection of individual spin species via frequency-modulated charge pumping

February 2, 2022
Author(s)
James Ashton, Mark Anders, Jason Ryan
We utilize the recently developed frequency-modulated charge pumping technique to detect a single charge per cycle, which strongly suggests a single Si/SiO2 interface trap. This demonstration in sub-micron MOSFETs, in which scaling of the gate oxide yields

Model for the Bipolar Amplification Effect

December 10, 2021
Author(s)
James Ashton, Stephen Moxim, Ashton Purcell, Patrick Lenahan, Jason Ryan
We present a model based on Fitzgerald-Grove surface recombination for the bipolar amplification effect (BAE) measurement, which is widely utilized in electrically detected magnetic resonance (EDMR) to measure reliability and performance-limiting interface
