S.Carallo, R.Cingolani and G.Gigli, Appl. Phys. Lett., 96, 133305 (31/03/2010) -collaboration with ST
2) Transistor a effetto di campo a base di molecole organiche emettitore di luce – V.Maiorano, G.Gigli – Italian patent N° IT
RM20100107 (A1) (13/09/2011)
3) Organic light emitting field effect transistor – V.Maiorano, G.Gigli – International Patent WO 2011110664 (A1) (15/09/2011)
4) Organic light emitting field effect transistor – V.Maiorano, G.Gigli – European Patent N°11707864.2 (26-10-2012 )to be approved
Main features of the new concept trylayer doped
heterostructure
1) Large emission area along the whole transistor channel
2) Light emission controlled by doping concentration
3) High output current at relative low driving voltages
4) Suitable voltage gain for their integration in planar complex
device (AM display - boolean circuits)
Organic light-emitting field effect transistors (OLEFET) with doped transport layers
