Non-Langevin recombination demonstrated in LEFETs

Recently, I have found this great scientific paper, and those who know me well also know that I do say that too often :)

The work presents light emitting field effect transistors (LEFETs), where non-Langevin charge carrier recombination was observed. The material was structured F8BT polymer. The approach used was indeed very innovative and original - widening of light emission zone. Indeed, in non-Langevin systems the recombination zone is expected to extended and broaded, as our numerical simulations confirm that too.

Why do I think this paper is important? Because organic LEFETs present a novel type of device geometry, where non-Langevin recombination is demonstrated after its first appearance in organic bulk-heterojunction solar cells.
