Abstract: Temperature characteristics are important for the performance of organic thin film devices.On the basis of the hopping theory of Miller-Abrahams,an analytical model of charge transport for bilayer organic devices under the organic-organic interface limited current conduction is developed.The dependence of current,field,and carrier distribution in bilayer organic devices with the structure of "injection electrode/LayerI/LayerII/collection electrode" on temperature are numerically analyzed.We conclude that,for a given applied voltage,when temperature is raised,the voltage of LayerIwill increase,and the field will be higher.Meanwhile,the voltage of LayerIIwill decrease,the field will become weaker accordingly,and the current of the device will increase.
