Hydration of mixed halide perovskites investigated by Fourier transform infrared spectroscopy

open access: yesAPL Materials, 2019
The mixed lead halide perovskites are promising candidates for solar cells, but the intrinsic instabilities due to phase segregation, halide migration, and hydration hinder the practical applications.

Mid-Infrared Intersubband Absorption from P-Ge Quantum Wells on Si [PDF]

open access: yes, 2016
Mid-infrared intersubband absorption from p-Ge quantum wells with Si0.5Ge0.5 barriers grown on a Si substrate is demonstrated from 6 to 9 μm wavelength at room temperature and can be tuned by adjusting the quantum well thickness.
