Sub-picosecond acoustic pulses at buried GaP/Si interfaces
Kunie Ishioka, Avinash Rustagi, Andreas Beyer +5
We report on the optical generation and detection of ultrashort acoustic pulses that propagate in three-dimensional semiconductor crystals. Photoexcitaiton of lattice-matched GaP l…
Direct Characterization of Band Bending in GaP/Si(001) Heterostructures with Hard X-ray Photoelectron Spectroscopy
Martin Schmid, Kunie Ishioka, Andreas Beyer +9
We apply hard X-ray photoelectron spectroscopy (HAXPES) to investigate the electronic structures in ~50-nm thick epitaxial GaP layers grown on Si(001) under different conditions. D…
Intrinsic coherent acoustic phonons in indirect band gap semiconductors Si and GaP
Kunie Ishioka, Avinash Rustagi, Ulrich Hoefer +2
We report on the intrinsic optical generation and detection of coherent acoustic phonons at (001)-oriented bulk Si and GaP without metallic phonon transducer structures. Photoexcit…
