Exploring the Charge Density Wave phase of 1-TaSe: Mott or Charge-transfer Gap?
C. J. Sayers, G. Cerullo, Y. Zhang +8
1-TaSe is widely believed to host a Mott metal-insulator transition in the charge density wave (CDW) phase according to the spectroscopic observation of a band gap that exte…
Spectrally resolving the phase and amplitude of coherent phonons in the charge density wave state of 1-TaSe
Charles J. Sayers, Stefano Dal Conte, Daniel Wolverson +4
The excitation and detection of coherent phonons has given unique insights into condensed matter, in particular for materials with strong electron-phonon coupling. We report a stud…
Excitonic and lattice contributions to the charge density wave in 1T-TiSe revealed by a phonon bottleneck
Hamoon Hedayat, Charles J. Sayers, Davide Bugini +10
Understanding collective electronic states such as superconductivity and charge density waves is pivotal for fundamental science and applications. The layered transition metal dich…
Binding Energy of Charged Excitons in ZnSe-based Quantum Wells
G. V. Astakhov, D. R. Yakovlev, V. P. Kochereshko +9
Excitons and charged excitons (trions) are investigated in ZnSe-based quantum well structures with (Zn,Be,Mg)Se and (Zn,Mg)(S,Se) barriers by means of magneto-optical spectroscopy.…
