CDW signatures in the electronic structure of LaSb2 at 13 K and metal-insulator transition
I. Palacio, J. Obando-Guevara, L. Chen +11
Light rare-earth antimonide LaSb2 is a material susceptible to nesting and exhibits a Charge Density Wave (CDW) at 355 K as well as superconductivity below 1.2 K. In the seek for a…
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…
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…
Time resolved photoemission spectroscopy of electronic cooling and localization in CHNHPbI crystals
Zhesheng Chen, Min-i Lee, Zailan Zhang +10
We measure the surface of CHNHPbI single crystals by making use of two photon photoemission spectroscopy. Our method monitors the electronic distribution of photoexcite…
Stable topological insulators achieved using high energy electron beams
Lukas Zhao, Marcin Konczykowski, Haiming Deng +9
Topological insulators are transformative quantum solids with immune-to-disorder metallic surface states having Dirac band structure. Ubiquitous charged bulk defects, however, pull…
