Abstract:
We have fabricated a series of hole only devices with tungsten oxide (WO3) and molybdenum oxide (MoO3) n-doping materials in N,N'-diphenyl-N,N'-bis(1,1'-biphenyl)-4,4'-diamine (NPB) hole transport layer, and electron only devices with CsF and Cs2CO3 p-doping materials in 4,7-diphenyl-1,10-phenanthroline (Bphen) electron transport layer. Current-voltage characteristics and conductivity of these devices are investigated. The optimal conditions for ohmic injection and low resistance properties, and process margins of each dopant are reported in this paper.

Biasing of P-N Junction
In equilibrium, no external voltage is applied across the p-n junction. The depletion region is formed at the junction interface due to the diffusion of carriers, which leaves behind charged dopants, acceptors on the p-side, and donors on the n-side. These immobile charges create an electric field that prevents further diffusion of carriers. The related energy band...
MOSFET: Enhancement Mode
In their basic form, enhancement-mode MOSFETs are typically non-conductive when the gate-source voltage (Vgs) is zero. This default 'off' state means no current...
