Solution-processable semiconductors hold promise in enabling applications requiring cost-effective electronics at scale but suffer from low performance limited by defects. We show that ordered defect compound semiconductor CuInSe, which forms regular defect complexes with defect-pair compensation, can simultaneously achieve high performance and solution processability. CuInSe transistors exhibit defect-tolerant, band-like transport supplying an output current above 35 microamperes per micrometer, with a large on/off ratio greater than 10, a small subthreshold swing of 189 ± 21 millivolts per decade, and a high field-effect mobility of 58 ± 10 square centimeters per volt per second, with excellent uniformity and stability, superior to devices built on its less defective parent compound CuInSe, analogous binary compound InSe, and other solution-deposited semiconductors.

After this event, average compliance with hand hygiene increased from 72% (95% CI, 70%-74%) in 2013 to 85% (95% CI, 83%-87%) in June-July 2014, and the conceptual understanding of good hand hygiene practices improved.
