There has been an urgent need in consumer electronics for infrared optoelectronics including light emitting diodes and photodetectors. To date, however, infrared optoelectronics are served by costly CMOS-incompatible III-V semiconductors. Recently, a new class of semiconductors that addresses the CMOS compatibility issue has emerged based on colloidal quantum dots. When it comes to consumer electronics, the use of RoHS-compliant materials is a prerequisite and therefore there is a strong need for the development of high-performance devices based on environmentally friendly elements — something that in the infrared had remained elusive.
