Spectroscopic view of ultrafast charge carrier dynamics in single- and bilayer transition metal dichalcogenide semiconductors
P. Majchrzak, K. Volckaert, A. G. Cabo +24
The quasiparticle spectra of atomically thin semiconducting transition metal dichalcogenides (TMDCs) and their response to an ultrafast optical excitation critically depend on inte…
A Novel Quasi-One-Dimensional Topological Insulator in Bismuth Iodide -BiI
Gabriel Autès, Anna Isaeva, Luca Moreschini +16
Recent progress in the field of topological states of matter(1,2) has largely been initiated by the discovery of bismuth and antimony chalcogenide bulk topological insulators (TIs)…
Ultrafast Band Structure Control of a Two-Dimensional Heterostructure
Søren Ulstrup, Antonija Grubišić Čabo, Jill A. Miwa +12
The electronic structure of two-dimensional (2D) semiconductors can be significantly altered by screening effects, either from free charge carriers in the material itself, or by en…
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…
Observation of Ultrafast Free Carrier Dynamics in Single Layer MoS
Antonija Grubišić Čabo, Jill A. Miwa, Signe S. Grønborg +11
The dynamics of excited electrons and holes in single layer (SL) MoS have so far been difficult to disentangle from the excitons that dominate the optical response of this mate…
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,…
