Embodiment Construction
[0008] see figure 1 As shown, the method for preparing a co-doped zinc oxide film provided by atomic layer deposition in the embodiment of the present invention includes: treating a silicon substrate or a glass substrate with concentrated sulfuric acid hydrogen peroxide, and then ultrasonically cleaning it with ultrapure water, N 2 Blow dry, wherein concentrated sulfuric acid:hydrogen peroxide=4:1. Put the substrate into the atomic layer deposition chamber, turn on the atomic layer deposition equipment, adjust the working parameters, vacuumize and heat the bottom to achieve various working environments required for the experiment; conduct multiple groups of N-Zr co-doped zinc oxide thin films Composite deposition, namely Zn(C 2 h 5 ) 2 / N 2 / H 2 O / N 2 / plasma N 2 / N 2 / Zn(C 2 h 5 ) 2 / N 2 / (CH 3 CH 2 O) 4 Zr / N 2 / H 2 O / N 2 / plasma N 2 / N 2 =0.15s / 50s / 0.07s / 50s / 10s / 50s / 0.08s / 50s / 0.08s / 50s / 0.07s / 50s / 10s / 50s. Wherein the flow rate of nitrogen is 1sccm-1000scc...
