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…
Direct measurement of key exciton properties: energy, dynamics and spatial distribution of the wave function
Shuo Dong, Michele Puppin, Tommaso Pincelli +15
Excitons, Coulomb-bound electron-hole pairs, are the fundamental excitations governing the optoelectronic properties of semiconductors. While optical signatures of excitons have be…
Revealing Hidden Orbital Pseudospin Texture with Time-Reversal Dichroism in Photoelectron Angular Distributions
Samuel Beaulieu, Jakub Schusser, Shuo Dong +12
We performed angle-resolved photoemission spectroscopy (ARPES) of bulk 2H-WSe for different crystal orientations linked to each other by time-reversal symmetry. We introduce a…
Time- and momentum-resolved photoemission studies using time-of-flight momentum microscopy at a free-electron laser
Dmytro Kutnyakhov, Rui Patrick Xian, Maciej Dendzik +38
Time-resolved photoemission with ultrafast pump and probe pulses is an emerging technique with wide application potential. Real-time recording of non-equilibrium electronic process…
Quasi-free-standing single-layer WS2 achieved by intercalation
Sanjoy K. Mahatha, Maciej Dendzik, Charlotte E. Sanders +4
Large-area and high-quality single-layer transition metal dichalcogenides can be synthesized by epitaxial growth on single-crystal substrates. An important advantage of this approa…
Spin structure of K valleys in single-layer WS on Au(111)
Philipp Eickholt, Charlotte Sanders, Maciej Dendzik +6
The spin structure of the valence and conduction bands at the and ' valleys of single-layer WS on Au(111) is determined by spin- and…
