Dynamics of electronic states in the insulating Intermediate surface phase of 1T-TaS
Jingwei Dong, Weiyan Qi, Dongbin Shin +14
This article reports a comparative study of bulk and surface properties in the transition metal dichalcogenide 1T-TaS. When heating the sample, the surface displays an intermed…
Electronic dispersion, correlations and stacking in the photoexcited state of 1T-TaS
Jingwei Dong, Dongbin Shin, Ernest Pastor +11
Here we perform angle and time-resolved photoelectron spectroscopy on the commensurate Charge Density Wave (CDW) phase of 1T-TaS. Data with different probe pulse polarization a…
Low-Temperature Insulating Phase of the Si(111)--77 Surface
S. Modesti, P. M. Sheverdyaeva, P. Moras +5
We investigated the electronic structure of the Si(111)--77 surface below 20 K by scanning tunneling and photoemission spectroscopies and by density functional theory calcu…
Photoinduced renormalization of Dirac states in BaNiS
Niloufar Nilforoushan, Michele Casula, Marco Caputo +9
By means of pump-probe time- and angle-resolved photoelectron spectroscopy, we provide evidence of a sizeable reduction of the Fermi velocity of out-of-equilibrium Dirac bands in t…
Tuning Dirac nodes with correlated d-electrons in BaCo_{1-x}Ni_{x}S_{2}
N. Nilforoushan, M. Casula, A. Amaricci +15
Dirac fermions play a central role in the study of topological phases, for they can generate a variety of exotic states, such as Weyl semimetals and topological insulators. The con…
Ultrafast electrons dynamics reveal the high potential of InSe for hot carrier optoelectronics
Zhesheng Chen, Christine Giorgetti, Jelena Sjakste +9
We monitor the dynamics of hot carriers in InSe by means of two photons photoelectron spectroscopy (2PPE). The electrons excited by photons of 3.12 eV experience a manifold relaxat…
