Are organic LEDs and Lasers similar to inorganic devices?

In this paper, we compare chemically prepared materials to those grown under high vacuum conditions (MOCVD, MBE, etc.). We also compare colloidal grown semiconducting nanocrystals to quantum dots and thin film organic devices to inorganic ones. We also show that unique properties of organic materials emphasize different physical processes such that when a non ab-initio model is used, like in any device analysis, the device-physics looks different. We touch upon device analysis and design which are unique to organic devices and emphasize the way "abundant-models" can be modified/extended to allow engineering work.
