Robust coherent phonon mode at GaP/Si(001) heterointerface
Kunie Ishioka, Gerson Mette, Steven Youngkin +5
Lattice-matched GaP layers without extended defects can be grown on Si(001) substrate via a two-step growth procedure, consisting of low-temperature nucleation followed by high-tem…
Strongly coupled interface electronic states and interface phonon mode at GaP/Si(001)
Gerson Mette, Kunie Ishioka, Steven Youngkin +3
Ultrafast carrier and phonon dynamics at the buried heterointerface of GaP/Si(001) are investigated by means of two-color pump-probe reflectivity measurements. The carrier-induced…
Separation of interface and substrate carrier dynamics at a heterointerface based on coherent optical phonons
Kunie Ishioka, Ethan Angerhoffer, Christopher J. Stanton +4
Transient reflectivity spectroscopy is widely used to study ultrafast carrier- and phonon-dynamics in semiconductors. In their heterostructures, it is often not straightforward to…
Probing the ultrafast gain and refractive index dynamics of a VECSEL
Christian Kriso, Tim Bergmeier, Nathan Giannini +9
Typically, strong gain saturation and gain dynamics play a crucial role in semiconductor laser mode-locking. While there have been several investigations of the ultrafast gain dyna…
Ultrafast charge-transfer dynamics in twisted MoS/WSe heterostructures
J. E. Zimmermann, M. Axt, F. Mooshammer +5
Two-dimensional transition metal dichalcogenides (TMD) offer a unique platform for creating van-der-Waals heterojunctions with fascinating physical properties and promising applica…
Site-specific reactivity of ethylene at distorted dangling bond configurations on Si(001)
Josua Pecher, Gerson Mette, Michael Dürr +1
We report differences in adsorption and reaction energetics for ethylene on Si(001) with respect to different dangling bond configurations induced by hydrogen precoverage as obtain…
