Suitability of lithium doped electron injection layers for organic semiconductor lasers
Lithium doped 2 , 2 ′ , 2 ″ -(1,3,5-benzenetryl)tris(1-phenyl)- 1 H -benzimidazol (TPBi) as electron injection layer in organic laser diodes is investigated. The optical material absorption of optimum doped Li:TPBi is as low as 300 cm − 1 at λ = 600 nm . Kelvin probe analysis demonstrates that thin...
