Phase manipulation of terahertz waves by work function engineering in metal-graphite structures
Muhammad Irfan, Soo Kyung Lee, Jong-Hyuk Yim +2
We manipulate the transient terahertz (THz) waves emitted from metal-graphite interfaces, where potential barriers were formed because of work function differences. To adaptively c…

Transverse Acoustic Phonon Transistor Based on Asymmetric Potential Distribution
H. Jeong, Y. D. Jho, C. J. Stanton
We experimentally demonstrate a transverse acoustic (TA) phonon transistor. Phonons are coherently initiated by femtosecond photocarrier screening on potential gradients. Although…

Exceptionally Slow Rise in Differential Reflectivity Spectra of Excitons in GaN: Effect of Excitation-induced Dephasing
Y. D. Jho, D. S. Kim, A. J. Fischer +4
Femtosecond pump-probe (PP) differential reflectivity spectroscopy (DRS) and four-wave mixing (FWM) experiments were performed simultaneously to study the initial temporal dynamics…
