The research topic proposed by the groups at Humboldt-Universität zu Berlin and the Institute for Physics of Microstructure of the Russian Academy of Sciences is the experimental investigation of excited states in boron-doped diamond crystals. The lifetimes of the excited states will be determined by mid-infrared pump-probe spectroscopy and time-resolving Fourier transform infrared absorption spectroscopy. The interaction of excited states with phonon bands will be studied by high-field magneto-optical spectroscopy. The results will be compared with a theoretical model of hole capture in boron-doped diamond. Based on these results we will investigate the potential of boron-doped diamond as a emitter for mid-infrared radiation. The HUB team has about 15 years of experience in semiconductor spectroscopy, in particular with time-resolving techniques, as well as on silicon terahertz lasers and the development of fast terahertz detectors with ps-ns response times. The proposed research is based on this heritage.

Humboldt-Universität zu Berlin和俄罗斯科学院微观结构物理研究所的研究小组提出的研究课题是对掺硼金刚石晶体激发态的实验研究。激发态的寿命将由中红外泵浦探测光谱和时间分辨傅里叶变换红外吸收光谱测定。利用高场磁光谱学研究激发态与声子带的相互作用。结果将与掺硼金刚石中空穴捕获的理论模型进行比较。基于这些结果，我们将研究掺硼金刚石作为中红外辐射发射器的潜力。HUB团队在半导体光谱学方面拥有大约15年的经验，特别是时间分辨技术，以及硅太赫兹激光器和具有ps-ns响应时间的快速太赫兹探测器的开发。拟议的研究就是基于这一传统。
