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

Modern 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.

Modern Faraday Rotation Studies to Probe the Solar Wind

Frontiers in Astronomy and Space Sciences, 2022
For decades, observations of Faraday rotation have provided unique insights into the plasma density and magnetic field structure of the solar wind. Faraday rotation (FR) is the rotation of the plane of polarization when linearly polarized radiation ...

The Faraday Effect Tracker of Coronal and Heliospheric Structures (FETCH) instrument

Frontiers in Astronomy and Space Sciences, 2023
There continue to be open questions regarding the solar wind and coronal mass ejections (CMEs). For example: how do magnetic fields within CMEs and corotating/stream interaction regions (CIRs/SIRs) evolve in the inner heliosphere?

Solar Sources of Interplanetary Magnetic Clouds Leading to Helicity Prediction

Space Weather, Volume 16, Issue 11, Page 1668-1685, November 2018., 2018
Abstract This study identifies the solar origins of magnetic clouds that are observed at 1 AU and predicts the helical handedness of these clouds from the solar surface magnetic fields. We started with the magnetic clouds listed by the Magnetic Field Investigation (MFI) team supporting NASA's Wind spacecraft in what is known as the MFI table and worked

Reconstructing Historical Solar Indices for Predicting Past Space Weather Events

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Modeling and forecasting the near‐Earth space environment, specifically the thermosphere, is particularly important because it affects the motion of low‐Earth orbit objects through atmospheric drag. Solar indices such as F10.7, S10.7, M10.7, and Y10.7 are commonly used as inputs to ionospheric and thermospheric density models.
