Phonon-assisted inter-valley scattering determines ultrafast exciton dynamics in MoSe bilayers
Sophia Helmrich, Kevin Sampson, Di Huang +10
While valleys (energy extrema) are present in all band structures of solids, their preeminent role in determining exciton resonances and dynamics in atomically thin transition meta…
Superior Photo-carrier Diffusion Dynamics in Organic-inorganic Hybrid Perovskites Revealed by Spatiotemporal Conductivity Imaging
Xuejian Ma, Fei Zhang, Zhaodong Chu +9
The outstanding performance of organic-inorganic metal trihalide solar cells benefits from the exceptional photo-physical properties of both electrons and holes in the material. He…
Spin-Phonon Interaction in Yttrium Iron Garnet
Kevin S. Olsson, Jeongheon Choe, Martin Rodriguez-Vega +6
Spin-phonon interaction is an important channel for spin and energy relaxation in magnetic insulators. Understanding this interaction is critical for developing magnetic insulator-…
Experimental measurement of the intrinsic excitonic wavefunction
Michael K. L. Man, Julien Madéo, Chakradhar Sahoo +15
An exciton, a two-body composite quasiparticle formed of an electron and hole, is a fundamental optical excitation in condensed-matter systems. Since its discovery nearly a century…
Momentum resolved ground/excited states and the ultra-fast excited state dynamics of monolayer MoS2
Woojoo Lee, Yi Lin, Li-Shuan Lu +6
The emergence of transition metal dichalcogenides (TMD) as crystalline atomically thin semiconductors has created a tremendous amount of scientific and technological interest. Many…
Twist Angle Dependent Interlayer Exciton Lifetimes in van der Waals Heterostructures
Junho Choi, Matthias Florian, Alexander Steinhoff +15
In van der Waals (vdW) heterostructures formed by stacking two monolayers of transition metal dichalcogenides, multiple exciton resonances with highly tunable properties are formed…
