NMR study of optically hyperpolarized phosphorus donor nuclei in silicon
P. Gumann, H. Haas, S. Sheldon +4
We use above-bandgap optical excitation, via a 1047 nm laser, to hyperpolarize the P spins in low-doped (N cm) natural abundance silicon at 4.2 K…
Chemisorption of water on the surface of silicon microparticles measured by DNP-enhanced NMR
Mallory L. Guy, Kipp J. van Schooten, Lihuang Zhu +1
We use dynamic nuclear polarization (DNP) enhanced nuclear magnetic resonance (NMR) at liquid helium temperatures to directly detect hydrogen attached to the surface of silicon mic…
Optical dependence of electrically-detected magnetic resonance in lightly-doped Si:P devices
Lihuang Zhu, Kipp J. van Schooten, Mallory. L. Guy +1
Electrically-detected magnetic resonance (EDMR) provides a highly sensitive method for reading out the state of donor spins in silicon. The technique relies on a spin-dependent rec…
Design and characterization of a W-band system for modulated DNP experiments
Mallory L. Guy, Lihuang Zhu, Chandrasekhar Ramanathan
Magnetic-field and microwave-frequency modulated DNP experiments have been shown to yield improved enhancements over conventional DNP techniques, and even to shorten polarization b…
