Over the past few decades, researchers, and now companies, have begun spin-coating optoelectronic materials as a lower-cost alternative to epitaxially grown devices. Now, a group of researchers at the University of Toronto have demonstrated that one such “wet” semiconductor device with a painted-on liquid nanolayer can outperform standard chips.
