Challenges and Opportunities in Magnetospheric Space Weather Prediction

open access: yesSpace Weather, Volume 18, Issue 3, March 2020., 2020
Abstract Space Weather is the study of the dynamics of the coupled Solar‐Terrestrial environment, as these dynamics impact technological systems and human activity. This paper reviews a selection of the advances, challenges, and new opportunities for magnetospheric space weather, and while the focus is on specific phenomena, many other aspects of space

Thank You to Our 2019 Reviewers

open access: yesSpace Weather, Volume 18, Issue 3, March 2020., 2020
Abstract Peer reviewing is the foundation of modern scholarship, with external specialists being asked to fairly check and evaluate submitted work. This difficult and often time‐consuming activity is performed voluntarily, with the understanding that one's own scholarship shall benefit down the line from a careful analysis of its assumption, results ...

Control of yellow photoluminescence in AlGaN/GaN heterostructures [PDF]

open access: yesModern Electronic Materials, 2019
Photoluminescence with the peak corresponding to yellow color of the visible spectrum (so-called yellow luminescence) originates from deep levels in the GaN buffer layers of heterostructures and depends on heterostructure growth conditions.
