研究目的
To investigate the damage characteristics of the indium-tin-oxide (ITO) and polyimide (PI) films under laser irradiation, focusing on the effects of the PI alignment layer on the laser damage resistance of the ITO film.
研究成果
The study concludes that the PI alignment layer increases the LIDT of ITO films by providing favorable mechanical properties. The damage mechanisms differ between ITO/Glass and PI/ITO/Glass samples, with the latter showing higher resistance to laser damage due to the PI layer's mechanical strength.
研究不足
The study is limited to the specific conditions of laser irradiation (1064 nm, nanosecond pulse) and the particular materials (ITO and PI films) used. The temperature model's accuracy is compromised after ITO film melting and vaporization.
1：Experimental Design and Method Selection:
The study involves irradiating ITO/Glass and PI/ITO/Glass samples with a 1064 nm Nd:YAG laser to observe damage characteristics.
2：Sample Selection and Data Sources:
Samples include 25-nm-thick ITO films on soda-lime glasses and 80-nm-thick PI films spin-deposited onto ITO-coated glasses.
3：List of Experimental Equipment and Materials:
Equipment includes a laserkids-20 laser source, on-line CCD detection system, Leica optical microscope, Zeiss SEM, and Bruker Dektak Xt surface profiler.
4：Experimental Procedures and Operational Workflow:
Laser damage experiments were performed with a 12-ns pulse at normal incidence, with one pulse per test site and ten sites tested per fluence.
5：Data Analysis Methods:
LIDTs were determined using the on-line CCD detection technique, and damage morphologies were analyzed using optical microscopy and SEM.
