Gd3+-Doped alpha-CsPbI3 nanocrystals with better phase stability and optical properties
(American Chemical Society, 2019-10)
Black alpha-CsPbI3 perovskites are unable to maintain their phase stability under room conditions; hence, the alpha-CsPbI3 phase transforms into a thermodynamically stable yellow delta-CsPbI3 phase within a few days, which ...
Raman fingerprint of stacking order in HfS2-Ca(OH)(2) heterobilayer
(American Physical Society, 2019-05)
Using density functional theory-based first-principles calculations, we investigate the stacking order dependence of the electronic and vibrational properties of HfS2-Ca(OH)(2) heterobilayer structures. It is shown that ...
