Photon Echo in Uniaxially Stressed Germanium with Antimony Donors
R. Kh. Zhukavin, V. D. Kukotenko, P. A. Bushuykin +8
Photon echo is observed in n-type Ge uniaxially stressed along the [111] crystallographic direction, with a coherence relaxation time of 300 ps. The nonlinear polarization responsi…
