A new kind of "wire" for moving excitons, developed at the University of Michigan, could help enable a new class of devices, perhaps including room temperature quantum computers.
What's more, the team observed a dramatic violation of Einstein's relation, used to describe how particles spread out in space, and leveraged it to move excitons in much smaller packages than previously possible.
"Nature uses excitons in photosynthesis. We use excitons in OLED displays and some LEDs and solar cells," said Parag Deotare, co-corresponding author of the study in ACS Nano supervising the experimental work, and an associate professor of electrical and computer engineering. The study is titled, Enhanced Exciton-Drift Transport through Suppressed Diffusion in One-Dimensional Guides.
"The ability to move excitons where we want will help us improve the efficiency of devices that already use excitons and expand excitonics into computing."
