New concepts for high-sensitivity pulsed electrically detected magnetic resonance

电检测磁共振(EDMR)的高灵敏度与基于天线的微波发射和借助任意波形整形共振激励脉冲的宽带能力相结合。带状线射频和微波天线在产生所需高频磁场的效率方面进行了优化，并进行了从2 GHz到18 GHz的脉冲EDMR实验。通过使用绝热脉冲，完全缓解了与高效率相关的强去相。在第二个资助期，我们进一步增加了技术的带宽，研究了磁场的空间分布，开发了特定于EDMR的最佳控制脉冲，并将新方法应用于与量子信息处理和可再生能源相关的主题问题。

The high sensitivity of electrically detected magnetic resonance (EDMR) is combined with the broadband capabilities of antenna-based microwave delivery and the shaping of the resonance excitation pulses with the help of arbitrary waveforms. Stripline radiofrequency and microwave antennae have been optimized with respect to the efficiency, with which they generate the required high-frequency magnetic fields, and pulsed EDMR experiments have been performed from 2 to 18 GHz. The strong dephasing linked to the high efficiency is fully mitigated by the use of adiabatic pulses. In the second funding period, we further increase the bandwidth of the technique, investigate the spatial distribution of the magnetic fields, develop optimum control pulses specific to EDMR and apply the new method to topical issues relating to quantum information processing and renewable energies.
