A new helical InSeI polymorph: crystal structure and polarized Raman spectroscopy study
Lucía Olano-Vegas, Davide Spirito, Evgeny Modin +7
Tetragonal InSeI is an interesting low-dimensional metal chalcohalide due to its composition and anisotropic crystal structure composed of helical chains, which give rise to optoel…
Resolving the Metastable Si-XIII Structure through Convergent Theory and Experiment
Fabrizio Rovaris, Corrado Bongiorno, Anna Marzegalli +10
Silicon is the undisputed cornerstone of modern technology, with applications ranging from micro- and opto-electronics to quantum technologies. Recently, the exploration of its all…
Lattice dynamics in chiral tellurium by linear and circularly polarized Raman spectroscopy: crystal orientation and handedness
Davide Spirito, Sergio Marras, Beatriz Martín-García
Trigonal tellurium (Te) has attracted researchers' attention due to its transport and optical properties, which include electrical magneto-chiral anisotropy, spin polarization and…
Formation of Micrometer-Sized Textured Hexagonal Silicon Crystals via Nanoindentation
Mouad Bikerouin, Anna Marzegalli, Davide Spirito +10
We present a comprehensive study on the formation of micrometer-sized, textured hexagonal diamond silicon (hd-Si) crystals via nanoindentation followed by annealing. Utilizing adva…
Thermal expansion and temperature dependence of Raman modes in epitaxial layers of Ge and GeSn
Agnieszka Anna Corley-Wiciak, Diana Ryzhak, Marvin Hartwig Zoellner +7
Temperature dependence of vibrational modes in semiconductors depends on lattice thermal expansion and anharmonic phonon-phonon scattering. Evaluating the two contributions from ex…
