Emergent Dirac carriers across a pressure-induced Lifshitz transition in black phosphorus
P. Di Pietro, M. Mitrano, S. Caramazza +11
The phase diagrams of correlated systems like cuprates or pnictides high-temperature superconductors are characterized by a topological change of the Fermi surface under continuous…
Coexistence of pressure-induced structural phases in bulk black phosphorus: a combined x-ray diffraction and Raman study up to 18 GPa
B. Joseph, S. Caramazza, F. Capitani +7
We report a study of the structural phase transitions induced by pressure in bulk black phosphorus by using both synchrotron x-ray diffraction for pressures up to 12.2 GPa and Rama…
Polarization analysis of first- and second-order Raman scattering from MoTe single crystal
S. Caramazza, A. Collina, E. Stellino +2
We report on Raman experiments performed on a single crystal MoTe sample. The system belongs to the wide family of Transition Metal Dichalcogenides which includes several of th…
High-pressure behavior of methylammonium lead iodide (MAPbI3) hybrid perovskite
Francesco Capitani, Carlo Marini, Simone Caramazza +6
In this paper we provide an accurate high-pressure structural and optical study of MAPbI3 hybrid perovskite. Structural data show the presence of a phase transition towards an orth…
Raman phonon spectrum of the Dzyaloshinskii-Moriya helimagnet Ba2CuGe2O7
F. Capitani, S. Koval, R. Fittipaldi +9
The Raman spectrum of Ba2CuGe2O7, a tetragonal insulator which develops Dzyaloshinsky- Moriya helical magnetism below TN = 3.2 K, has been detected at temperatures varying from 300…
Two-band conductivity of a FeSeTe film by reflectance measurements in the terahertz and infrared range
A. Perucchi, B. Joseph, S. Caramazza +7
We report an infrared spectroscopy study of a 200 nm thick FeSeTe film grown on LaAlO with T=13.7 K. We analyze the 20 K normal state absolute reflectance R…
Raman spectroscopy study of the interface structure in (CaCuO2)n/(SrTiO3)m superlattices
D. Di Castro, S. Caramazza, D. Innocenti +4
Raman spectra of CaCuO2/SrTiO3 superlattices show clear spectroscopic marker of two structures formed in CaCuO2 at the interface with SrTiO3. For non-superconducting superlattices,…
