[0026] Embodiment 2: with surface formula Alq 3 Single-carrier transport devices with nano- and micro-structure thin films as active layers

[0027] 1: Make Alq 3 The amorphous film method is as described in Example 1;

[0028] 2: Preparation of surface formula Alq 3 Nano-micron film as described in Example 1;

[0029] 3: Preparation based on surface Alq 3 Single-carrier transport devices of ultra-thin films with nano-microstructure

[0030] The device structure is: [ITO / surface Alq 3 (1000nm) / LiF(15nm) / Au(2000nm)]. Preparation of surface Alq on the surface of ITO 3 Nano-micron film, ITO as anode, LiF and Au as composite cathode. Conductivity test proves surface Alq 3 Nano-micro thin films have good hole injection and transport properties. The specific experimental data of device performance are as follows: figure 2 shown. As the voltage increases, the current of the device increases gradually, when the electric field strength reaches 16×10 4 At volts / cm, the curr...
