Broad-band polarization-insensitive all-dielectric metalens enabled by intentional off-resonance waveguiding at mid-wave infrared by Tanriover, Ibrahim, Demir, Hilmi Volkan

“…However, these approaches are limited to either narrow operation bands or suffer polarization dependency. Here, we propose and show high-index dielectric nanopillars operated as cylindrical waveguides deliberately in the off-resonance regime to achieve polarization independent wavefront control over wide spectral bands. …”

Optical and optoelectronic properties of Si nanocrystals embedded in dielectric matrix by Ding, Liang

“…However, the size-dependent PL could not originate from the direct band to band transition of nc-Si. Based on the knowledge of band structure of nc-Si obtained in this work, the size-dependent PL band could be attributed to the indirect band-to-band transition of the nc-Si assisted by the Si-O vibration at the interface of nc-Si/SiO2. …”

Topological phase transition induced by gain and loss in a photonic Chern insulator by Teo, Hau Tian, Xue, Haoran, Zhang, Baile

“…We present a design of a non-Hermitian photonic Chern insulator whose band topology can be tuned via gain and loss. It is found that, by continuously varying the gain and loss parameter, a topological phase transition can take place in the photonic crystal, accompanied by the closing and reopening of a Dirac cone. …”

Sb2S3-based extremely thin absorber solar cell by Kang, Aik Meng

“…Semiconductor-sensitised nanoporous solar cells are a derivative of dye-sensitised solar cells (DSSC) where a solid-state semiconductor absorber is used in place of the molecular dye of DSSC. In particular, solid-state cells have been drawing much attention recently due to its high light-harvesting capability, tunable band gap over a wide range and a large intrinsic dipole moment. …”

Interaction of longitudinal phonons with discrete breather in strained graphene by Evazzade, Iman, Roknabadi, Mahmood Rezaee, Mohammad Behdani, Moosavi, Fatemeh, Xiong, Daxing, Zhou, Kun, Dmitriev, Sergey V.

“…It is found that, for the longitudinal sound waves having frequencies below 6 THz, DB is transparent and thus no radiation of energy from DB takes place; whereas for those sound waves with higher frequencies within the acoustic (optical) phonon band, phonon is mainly transmitted (reflected) by DB, and concomitantly, DB radiates its energy when interacting with phonons. …”
