Evidence for Topological Band-to-Band Transitions in a Type-II Weyl Semimetal
Seyyedesadaf Pournia, Giriraj Jnawali, Samuel Linser +2
The ternary van der Waals material NbIrTe is a Type-II Weyl semimetal. We use a tunable circularly polarized mid-infrared laser to investigate the existence of band-to-band exc…
Band Splitting and Long-lived Carrier Recombination in Ferromagnetic CrSiTe3 Nanosheets
Giriraj Jnawali, Seyyedesadaf Pournia, Eli Zoghlin +4
Magnetic layered ternary chalcogenides hold great promise for future spin-optoelectronic devices in the two dimensional limit. Understanding how the properties of the materials are…
Band Structure and Polarization Effects in Photothermoelectric Spectroscopy of a Bi2Se3 Device
Seyyedesadaf Pournia, Giriraj Jnawali, Ryan F. Need +3
Bi2Se3 is a prototypical topological insulator which has a small band gap (~0.3 eV) and topologically protected conducting surface states. This material exhibits quite strong therm…
A Raman Probe of Phonons and Electron-phonon Interactions in NbIrTe4
Iraj Abbasian Shojaei, Seyyedesadaf Pournia, Congcong Le +6
The semimetal NbIrTe4 has been proposed to be a Type-II Weyl semimetal with 8 pairs of opposite Chirality Weyl nodes which are very close to the Fermi energy. This topological elec…
