Excitonic Devices and Transport Properties
We present a novel method for creating excitonic devices with low energy consumption. The method involves implementing specially designed perforated electrodes to create versatile potential energy landscapes for indirect excitons with virtually any geometric and energy profile. A ramp for excitons is realized with a perforated electrode. It successfully demonstrates control of indirect exciton transport. We also present spatially, spectrally and time resolved measurements of indirect exciton transport in magnetic fields. Large transport distances of indirect excitons allow their transport to be directly observed with optical imaging. The application of a magnetic field serving as a means to engineer the exciton mass in situ is found to have a dramatic effect on exciton transport.
