An emerging class of atomically thin materials, monolayer semiconductors has generated a great deal of buzz in the world of materials science. Monolayers hold promise in the development of transparent LED displays, ultra-high efficiency solar cells, photo detectors and nanoscale transistors. Their downside? The films are notoriously riddled with defects, killing their performance.

But a UCLA, Berkeley, and Lawrence Berkeley National Lab team, has found a simple way to fix these defects via an organic superacid...
