While tracking electrons moving through exotic materials, researchers have discovered intriguing properties not found in conventional, silicon-based semiconductors.
Unlike current silicon-based electronics, which shed most of the energy they consume as waste heat, the future is all about low-power computing. Known as spintronics, this technology relies on a quantum physical property of electrons—up or down spin—to process and store information, rather than moving them around with electricity as conventional computing does.
On the quest to making spintronic devices a reality, scientists at the University of Arizona are studying an exotic crop of materials known as transition metal dichalcogenides, or TMDs. TMDs have exciting properties lending themselves to new ways of processing and storing information and could provide the basis of future transistors and photovoltaics—and potentially even offer an avenue toward quantum computing.
