Trade-off between interface morphology and compositional homogeneity in AlGaAs/GaAs quantum wells revealed by multislice electron ptychography
Yiwei Ju, Han-Hsuan Wu, Amberly Ricks +7
AlGaAs/GaAs asymmetric coupled quantum wells (ACQWs) are promising platforms for enhanced second-order optical nonlinearities, with their performance strongly influenced by the str…
Emergent Moiré fringes in direct-grown quasicrystal
Jingwei Li, Kejie Bao, Honglin Sun +13
Quasicrystals represent a category of rarely structured solids that challenge traditional periodicity in crystal materials. Recent advancements in the synthesis of two-dimensional…
Inelastic electron scattering at large angles: the phonon polariton contribution
Hongbin Yang, Paul Zeiger, Andrea Konečná +11
We explore the inelastic electron scattering in SrTiO3, PbTiO3, and SiC in their phonon energy range, challenging the assumption that phonon polaritons are excluded at large angles…
Real-Space Visualization of Frequency-Dependent Anisotropy of Atomic Vibrations
Xingxu Yan, Paul M. Zeiger, Yifeng Huang +11
The underlying dielectric properties of materials, intertwined with intriguing phenomena such as topological polariton modes and anisotropic thermal conductivities, stem from the a…
