 | Boehme, Christoph | Effect of exchange coupling on coherently controlled spin-dependent transition rates | The effect of exchange interactions within spin pairs on spin-dependent transport and recombination rates through localized states in semiconductors during coherent electron-spin resonant excitation is studied theoretically. It is shown that for identical spin systems, significant quantitative diff... | Spin coherence; Electron spin nutations | 2008-06 |

 | Boehme, Christoph | Fast nuclear spin hyperpolarization of phosphorus in silicon | We experimentally demonstrate a method for obtaining nuclear spin hyperpolarization, that is, polarization significantly in excess of that expected at thermal equilibrium. By exploiting a nonequilibrium Overhauser process, driven by white light irradiation, we obtain more than 68% negative nuclear p... | Hyperpolarization; Spin coherence; Electrical readout | 2009-01 |

 | Boehme, Christoph | Long-lived spin coherence in silicon with an electrical spin trap readout | Pulsed electrically detected magnetic resonance of phosphorous (31P) in bulk crystalline silicon at very high magnetic fields (B0 > 8:5 T) and low temperatures (T = 2:8 K) is presented. We find that the spin-dependent capture and reemission of highly polarized (>95%) conduction electrons by equall... | Spin coherence | 2008-11 |

 | Boehme, Christoph | Electrical detection of spin coherence in silicon | Experimental evidence is presented showing that photocurrents in silicon can be used as highly sensitive readout probes for coherent spin states of localized electrons, the prime candidates for quantum bits in various semiconductor based quantum computer concepts. Conduction electrons are subjected ... | Spin coherence; Electronic transitions; Rabi oscillation | 2003-12 |

 | Boehme, Christoph | Room temperature electrical detection of spin coherence in C60 | An experimental demonstration of electrical detection of coherent spin motion of weakly coupled, localized electron spins in thin fullerene C60 films at room temperature is presented. Pulsed electrically detected magnetic resonance experiments on vertical photocurrents through Al/C60/ZnO samples sh... | Spin coherence | 2007-05 |
