Enhanced ultrafast relaxation rate in the Weyl semimetal phase of measured by time-and angle-resolved photoelectron spectroscopy
A. Crepaldi, G. Autès, G. Gatti +18
has recently been shown to realize in its low-temperature phase the type-II Weyl semimetal (WSM). We investigated by time- and angle- resolved photoelectron spect…
Evidence for a Strong Topological Insulator Phase in
G. Manzoni, L. Gragnaniello, G. Autès +16
The complex electronic properties of have recently stimulated in-depth investigations that assigned this material to either a topological insulator or a 3D Dirac…
Ultrafast Optical Control of the Electronic Properties of
G. Manzoni, A. Sterzi, A. Crepaldi +8
We report on the temperature dependence of the electronic properties, studied at equilibrium and out of equilibrium, by means of time and angle resolved photoelectron spec…
Tunable Carrier Multiplication and Cooling in Graphene
Jens C. Johannsen, Søren Ulstrup, Alberto Crepaldi +13
Time- and angle-resolved photoemission measurements on two doped graphene samples displaying different doping levels reveal remarkable differences in the ultrafast dynamics of the…
The momentum and photon energy dependence of the circular dichroic photoemission in the bulk Rashba semiconductors BiTeX (X = I, Br, Cl)
A. Crepaldi, F. Cilento, M. Zacchigna +14
Bulk Rashba systems BiTeX (X = I, Br, Cl) are emerging as important candidates for developing spintronics devices, because of the coexistence of spin-split bulk and surface states,…
Momentum resolved spin dynamics of bulk and surface excited states in the topological insulator
C. Cacho, A. Crepaldi, M. Battiato +16
The prospective of optically inducing a spin polarized current for spintronic devices has generated a vast interest in the out-of-equilibrium electronic and spin structure of topol…
