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…

Larger than 80% Valley Polarization of Free Carriers in Singly-Oriented Single Layer WS on Au(111)
H. Beyer, G. Rohde, A. Grubišić Čabo +10
We employ time- and angle-resolved photoemission spectroscopy to study the spin- and valley-selective photoexcitation and dynamics of free carriers at the K and K' points in singly…

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…
