Abstract

Solution-processed semiconductors are compatible with a range of substrates, which enables their direct integration with organic circuits1,2, microfluidics3,4, optical circuitry1,5 and commercial microelectronics. Ultrasensitive photodetectors based on solution-process colloidal quantum dots operating in both the visible and infrared have been demonstrated6,7, but these devices have poor response times (on the scale of seconds) to changes in illumination, and rapid-response devices based on a photodiode architecture suffer from low sensitivity8. Here, we show that the temporal response of these devices is determined by two components—electron drift, which is a fast process, and electron diffusion, which is a slow process. By building devices that exclude the diffusion component, we are able to demonstrate a >1,000-fold improvement in the sensitivity–bandwidth product of tuneable colloidal-quantum-dot photodiodes operating in the visible and infrared6,7,8. Previous photodetectors based on solution-processed colloidal quantum dots have demonstrated either rapid response times or high sensitivity. Researchers have now taken advantage of new insights into charge transport in these devices to build photodiodes that offer both rapid response times and high sensitivity.
