Efficient hole injection by doping of hexaazatriphenylene hexacarbonitrile in hole transport layer

Thin Solid Films, 2009
Abstract Hexaazatriphenylene-hexacarbonitrile (HAT) was used as a dopant in hole transport layer and hole injection properties of the HAT doped hole transport layer were studied. Hole injection was greatly improved by doping of the HAT in the hole transport material and a driving voltage was lowered by more than 3 V.

Enhanced Hole Transport in Polyfluorene Polymer by Using Hole Injection Layer

2014
Hole transport in poly(9,9-dioctylfluorene) (PFO) are measured by performing current density- voltage (J-V) measurements as a function of temperatures. For the J–V measurements, F4TCNQ is used as hole injection layer (HIL). Two different devices of PFO polymer are fabricated F4TCNQ having device configuration ITO/PFO/Au (with interface modification ...

Single-layer small molecular organic light emitting diodes without hole transport layer

Thin Solid Films, 2009
Abstract Organic light emitting devices based on tris-8-hydroxyquinoline aluminum with an ultra-thin insulating film instead of a hole-transporting layer were investigated. Three kinds of single-layer devices were fabricated with silicon dioxide (SiO 2 ), alumina (Al 2 O 3 ) or polytetrafluoroethylene (Teflon™) as the insulating films, and they ...
