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…
Direct observation of surface bandgap shrinkage and negative electronic compressibility in SrTiO3
Warakorn Jindata, Trung-Phuc Vo, Chutchawan Jaisuk +4
In this work, we investigate and compare the electronic structures of SrTiO3 and KTaO3 under ultraviolet (UV) light induced electron doping. Using angle-resolved photoemission spec…
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…
ARPES studies of Hf(0001) surface: flat bands formation in the dice lattice
Laxman Nagireddy, Saleem Ayaz Khan, Maria Christine Richter +8
We present the first electronic structure measurements of the Hf(0001) single-crystal surface using angle-resolved photoemission spectroscopy (ARPES). The ARPES results are support…
