Large Jahn-Teller shifts and splittings observed in halide perovskite CsPbBr3
Maryam Sajedi, Maxim Krivenkov, Dmitry Marchenko +7
Despite the fundamental role of Jahn-Teller effects of first and second order in shaping structural and electronic properties, there is hardly any observation in angle-resolved pho…
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…
Halide Perovskites as Spin-1 Dirac Materials
Dmitry Marchenko, Maryam Sajedi, Maxim Krivenkov +8
Halide perovskites are a promising class of materials for optoelectronic and photovoltaic applications, exhibiting high power conversion efficiency due to strong light absorption a…
The Potential of Geminate Pairs in Lead Halide Perovskite revealed via Time-resolved Photoluminescence
Hannes Hempel, Martin Stolterfoht, Orestis Karalis +1
Photoluminescence (PL) under continuous illumination is commonly employed to assess voltage losses in solar energy conversion materials. However, the early temporal evolution of th…
