Probing valley population imbalance in transition metal dichalcogenides via temperature-dependent second harmonic generation imaging
Leonidas Mouchliadis, Sotiris Psilodimitrakopoulos, George Miltos Maragkakis +5
Degenerate minima in momentum space - valleys - provide an additional degree of freedom that can be used for information transport and storage. Notably, such minima naturally exist…
Twist Angle mapping in layered WS2 by Polarization-Resolved Second Harmonic Generation
Sotiris Psilodimitrakopoulos, Leonidas Mouchliadis, Ioannis Paradisanos +4
Stacked atomically thin transition metal dichalcogenides (TMDs) exhibit fundamentally new physical properties compared to those of the individual layers. The twist angle between th…
Bragg Polaritons: Strong Coupling and Amplification in an Unfolded Microcavity
A. Askitopoulos, L. Mouchliadis, I. Iorsh +5
Periodic incorporation of quantum wells inside a one--dimensional Bragg structure is shown to enhance coherent coupling of excitons to the electromagnetic Bloch waves. We demonstra…
Supplementary Material to the Comment on "Photoluminescence Ring Formation in Coupled Quantum Wells: Excitonic Versus Ambipolar Diffusion"
A. L. Ivanov, E. A. Muljarov, L. Mouchliadis +1
This is a supplementary material to our Comment arXiv:0909.4265 on M. Stern, V. Garmider, E. Segre, M. Rappaport, V. Umansky, Y. Levinson, and I. Bar-Joseph, Phys. Rev. Lett. 101,…
Kinetics of the inner ring in the exciton emission pattern in GaAs coupled quantum wells
A. T. Hammack, L. V. Butov, J. Wilkes +4
We report on the kinetics of the inner ring in the exciton emission pattern. The formation time of the inner ring following the onset of the laser excitation is found to be about 3…
Comment on "Photoluminescence ring formation in coupled quantum wells: Excitonic versus ambipolar diffusion"
A. L. Ivanov, E. A. Muljarov, L. Mouchliadis +1
This is a comment on M. Stern, V. Garmider, E. Segre, M. Rappaport, V. Umansky, Y. Levinson, and I. Bar-Joseph, Phys. Rev. Lett. 101, 257402 (2008).
First-order spatial coherence of excitons in planar nanostructures: a k-filtering effect
L. Mouchliadis, A. L. Ivanov
We propose and analyze a k-filtering effect which gives rise to the drastic difference between the actual spatial coherence length of quasi-two-dimensional (quasi-2D) excitons or m…
Kinetics of indirect excitons in the optically-induced exciton trap
A. T. Hammack, L. V. Butov, L. Mouchliadis +2
We report on the kinetics of a low-temperature gas of indirect excitons in the optically-induced exciton trap. The excitons in the region of laser excitation are found to rapidly -…
