High-Speed Blue and Green Light-Emitting Diodes Using Polarization-Free GaN
Abstract
The goal of this proposed research is to substantiate, through a series of basic laboratory experiments and corroborative numerical modeling, the fundamental physics of CME interaction with the solar wind flow in the Sun’s outer corona. This research objective will be accomplished in two ways. First, detailed laboratory experiments of the fundamental plasma physics will be performed at U. New Mexico (UNM) using the existing Helicon-Cathode (HelCat) basic plasma science device, where CME-like structures moving into a flowing background plasma designed to represent the background solar wind can be generated. Second, the U. Michigan state-of-the-art 3D BATS-R-US MHD numerical code will be used to perform simulations of the propagation of plasma structures similar to those produced in the UNM experiments. The results of these two distinct approaches will be compared in a systematic way to validate the numerical model, and to further our understanding of CME propagation through the solar wind. The objective is to validate the numerical code under a controlled laboratory setting, allowing it to be applied with greater confidence to the less well-understood solar setting. This proposed project addresses a topic critical to the DoD mission – Space Weather prediction. It has significant student involvement, including two Ph.D. students conducting their dissertation research, and an undergraduate student. It would serve to build capability to perform space weather-relevant research at UNM, and would foster ties between UNM and the DoD Air Force Research Laboratory (AFRL) Space Weather Center, as well as with the larger space weather community, through the involvement of Dr. Nick Arge of AFRL, as a zero cost adviser.
