Conductive domain walls in ferroelectrics as tunable coherent THz radiation source
Ramaz Khomeriki, Kathrin Dörr, Jamal Berakdar
THz emission associated with currents in conductive domains in BiFeO following infrared radiation is theoretically investigated. This experimentally observed phenomenon is expl…
Efficient broadband terahertz generation by above band-gap excitation of the pyroelectric ZnSnN2
T. S. Seifert, H. Hempel, O. Gückstock +10
Terahertz (THz) radiation is a powerful probe of low-energy excitations in all phases of matter. However, it remains a challenge to find materials that efficiently generate THz rad…
Ultrafast electron dynamics upon above band-gap excitation in epitaxial LaFeO(001) thin films
Friederike Elisa Wührl, Antonia Rieche, Anne Oelschläger +2
Strong electron correlations in perovskite oxides give rise to rich and often unexpected electronic phenomena. In this study, we present a comprehensive surface-science investigati…
