Extended Data Table 2 Comparison of devices measured in different laboratories

From: Perovskite light-emitting diodes based on spontaneously formed submicrometre-scale structures

  1. *The perovskite LEDs (PeLEDs) were fabricated in the same batch at Nanjing Tech University. Each set of devices without encapsulations was simultaneously measured in air until the Optoelectronics Group, Cambridge, received its samples. As the transfer time from Nanjing to Cambridge is about eight days, the devices suffer from modest degradations.
  2. †The average peak EQE and standard deviation are from ten devices.
