Interface-sensitive nuclear magnetic resonance at a semiconductor heterojunction using hyperpolarization
Atsushi Goto, Kenjiro Hashi, Shinobu Ohki +1
We demonstrate an interface-sensitive NMR in a semiconducting nanostructure, where an NMR signal from the minute heterojunction region of a model heterojunction structure (In$_{0.4…
NMR study of thermally activated paramagnetism in metallic low-silica X zeolite filled with sodium atoms
Mutsuo Igarashi, Takehito Nakano, Pham Tan Thi +8
We report a \^{23}Na and \^{27}Al nuclear magnetic resonance (NMR) investigation of low-silica X (LSX) zeolite with chemical formula Na_{12}Al_{12}Si_{12}O_{48} (Na_{12}-LSX) loade…
Surface-sensitive NMR in optically pumped semiconductors
Atsushi Goto, Tadashi Shimizu, Kenjiro Hashi +1
We present a scheme of surface-sensitive nuclear magnetic resonance in optically pumped semiconductors, where an NMR signal from a part of the surface of a bulk compound semiconduc…
Dynamics of the electron-nuclear and heteronuclear polarization transfers in optically-oriented semi-insulating InP:Fe
Atsushi Goto, Kenjiro Hashi, Tadashi Shimizu +1
Dynamics of the electron-nuclear and heteronuclear polarization-transfer processes in the optically oriented semi-insulating iron-doped indium phosphide were investigated through t…
Optical pumping NMR in the compensated semiconductor InP:Fe
Atsushi Goto, Kenjiro Hashi, Tadashi Shimizu +6
The optical pumping NMR effect in the compensated semiconductor InP:Fe has been investigated in terms of the dependences of photon energy (E_p), helicity (sigma+-), and exposure ti…
A switchable controlled-NOT gate in a spin-chain NMR quantum computer
Atsushi Goto, Tadashi Shimizu, Kenjiro Hashi +1
A method of switching a controlled-NOT gate in a solid-stae NMR quantum computer is presented. Qubits of I=1/2 nuclear spins are placed periodically along a quantum spin chain (1-D…
