Valley Depolarization in Monolayer Transition-Metal Dichalcogenides with Zone-Corner Acoustic Phonons
Tae-Young Jeong, Soungmin Bae, Seong-Yeon Lee +3
Although single-layer transition-metal dichalcogenides with novel valley functionalities are promising candidate to realize valleytronic devices, the essential understanding of val…
Spectroscopic studies of atomic defects and bandgap renormalization in semiconducting monolayer transition metal dichalcogenides
Tae Young Jeong, Hakseong Kim, Sang-Jun Choi +5
Assessing atomic defect states and their ramifications on the electronic properties of two dimensional van der Waals semiconducting transition metal dichalcogenides (SC TMDs) is th…
External Modulation and Switching of Acoustic Phonons: Comparative Roles of Potential Distributions
H. Jeong, Y. D. Jho, S. H. Rhim +6
Acoustic phonons can be coherently generated by ultrafast displacive screening of potential gradients, often enhanced by the strong built-in piezoelectric fields, in wurtzite semic…
Polarization dependence of coherent phonon generation and detection in highly-aligned single-walled carbon nanotubes
L. G. Booshehri, C. L. Pint, G. D. Sanders +9
We have investigated the polarization dependence of the generation and detection of radial breathing mode (RBM) coherent phonons (CP) in highly-aligned single-walled carbon nanotub…
Resonant Coherent Phonon Generation in Single-Walled Carbon Nanotubes through Near-Band-Edge Excitation
Y. -S. Lim, J. -G. Ahn, J. -H. Kim +6
We have observed large-amplitude coherent phonon oscillations of radial breathing modes (RBMs) in single-walled carbon nanotubes excited through the lowest-energy (E11) interband t…
Monoclinic and Correlated Metal Phase in VO_2 as Evidence of the Mott Transition: Coherent Phonon Analysis
Hyun-Tak Kim, Yong-Wook Lee, Bong-Jun Kim +6
In femtosecond pump-probe measurements, the appearance of coherent phonon oscillations at 4.5 THz and 6.0 THz indicating the rutile metal phase of VO_2 does not occur simultaneousl…
