This thesis presents results crucial to the emerging field of indirect excitons. These specially designed quasiparticles give the unique opportunity to study fundamental properties of quantum degenerate Bose gases in semiconductors. Furthermore, indirect excitons allow for the creation of novel optoelectronic devices where excitons are used in place of electrons. Excitonic devices are explored for the development of advanced signal processing seamlessly coupled with optical communication. The thesis presents and describes the author's imaging experiments that led to the discovery of spin transport of excitons. The many firsts presented herein include the first studies of an excitonic conveyer, leading to the discovery of the dynamical localization-delocalization transition for excitons, and the first excitonic ramp and excitonic diode with no energy-dissipating voltage gradient.

With honesty and personal vunerability, Jason Leonard openly shares the hurts of his past and uses the pain as a platform upon which others can find fresh faith and renewed courage. Physical and emotional scars represent a story, a moment in one's life, and they show others that there is a history and healing. Your internal scars- invisible marks from heartbreak, mistakes, losses and disappointments- also represent stories of healing and restoration. Adopted at birth, Jason grew up in Wheaton Maryland. At the tender age of 18 he suffered a traumatic brain injury that changed the course of his life. Now at the age of 36 he is ready to tell his story. It's a story of courage, strength and the will to survive tragedy. Allow Jason to take you into his world, through his eyes and unique humor.
