Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Measuring Tail Risk

SSRN Electronic Journal, 2021
In this study we comprehensively investigate the usefulness of the tail risk measures proposed in the literature, evaluating the tail risk measures on the basis of their statistical and economic validity. Our main conclusion is that the option-implied measure of Bollerslev and Todorov (2011b) outperforms all others.

Commodity tail risks

Journal of Futures Markets, 2022
AbstractIn this study, we investigate the cross‐section of option‐implied tail risks in commodity markets. In contrast to findings from equity markets, left and right tail risks implied by option markets are both large. Commodity‐specific variables exert the largest influence on tail risk, while there is no evidence of systematic commodity factors that
