Wavelength‐Selective, High‐Speed, Self‐Powered Isotype Heterojunction n+‐ZnO/n‐Si Photodetector with Engineered and Tunable Spectral Response

open access: yesAdvanced Materials Technologies, EarlyView.
Wavelength‐selective ZnO/Si photodetectors, operating with no power supply. Engineering of the constituting materials converts them from white‐light sensitive to only NIR‐sensitive. When external power is applied, the wavelength selectivity of the devices can be tuned to different spectral ranges.

Coherent Phonons, Localization, and Slow Polaron Formation in Lead‐Free Gold Perovskite

open access: yesAdvanced Optical Materials, Volume 13, Issue 10, April 4, 2025.
Using ultrafast optical and Raman spectroscopy with bandstructure calculations, coupled electronic and vibrational dynamics are explained in Cesium Gold Bromide, a promising lead‐free perovskite. Photoexcitation is strongly coupled to Au─Br stretching phonon modes. Lattice relaxation along these modes leads to a polaronic state.
