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…
Hot carrier-assisted switching of the electron-phonon interaction in 1-VSe
Paulina Majchrzak, Sahar Pakdel, Deepnarayan Biswas +20
We apply an intense infrared laser pulse in order to perturb the electronic and vibrational states in the three-dimensional charge density wave material 1-VSe. Ultrafast sna…
Ultrafast triggering of insulator-metal transition in two-dimensional VSe
Deepnarayan Biswas, Alfred J. H. Jones, Paulina Majchrzak +24
Assembling transition metal dichalcogenides (TMDCs) at the two-dimensional (2D) limit is a promising approach for tailoring emerging states of matter such as superconductivity or c…
Momentum-resolved linear dichroism in bilayer MoS
Klara Volckaert, Habib Rostami, Deepnarayan Biswas +19
Inversion-symmetric crystals are optically isotropic and thus naively not expected to show dichroism effects in optical absorption and photoemission processes. Here, we find a stro…
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…
Tracking primary thermalization events in graphene with photoemission at extreme timescales
I. Gierz, F. Calegari, S. Aeschlimann +7
Direct and inverse Auger scattering are amongst the primary processes that mediate the thermalization of hot carriers in semiconductors. These two processes involve the annihilatio…
