Quantum dot solids: This generation’s silicon wafer?
Posted by Karen Hurst in categories: electronics, engineering, quantum physics, solar power, sustainability
Just as the single-crystal silicon wafer forever changed the nature of electronics 60 years ago, a group of Cornell researchers is hoping its work with quantum dot solids – crystals made out of crystals – can help usher in a new era in electronics.
The multidisciplinary team, led by Tobias Hanrath, associate professor in the Robert Frederick Smith School of Chemical and Biomolecular Engineering, and graduate student Kevin Whitham, has fashioned two-dimensional superstructures out of single-crystal building blocks. Through directed assembly and attachment processes, the lead selenide quantum dots are synthesized into larger crystals, then fused together to form atomically coherent square superlattices.
