MATLAB을 이용한 Ag Metal-mesh 기반의 투명 전극 특성 분석 = Characterization of Transparent Electrodes with Ag Metal-mesh using MATLAB

다국어 초록 (Multilingual Abstract)

It is well-known that optical transparence and electric resistance have a trade-off relationship intransparent electrodes. For this reason, developing methods to predict this relation have been important invarious fields of academic research as well as for industrial applications. Herein, we suggest a simple methodwhich reveals the relationship between optical transparence and electric resistance using MATLAB, basedon the geometric characteristics of a random metal network. Ag metal-mesh transparent electrodes werefabricated with various conditions using colloidal silica cracked-templates and a Radio Frequency (RF)sputtering system. MATLAB software was used to analyze structural images of the Ag mesh network,automatically quantifying the density and width of the Ag meshes. From these data, the transparency andsheet resistance values of the Ag mesh electrodes were predicted and compared with measured values.
Regarding transparency, the introduction of fitting parameters revealed minimal differences between theexperimental and predicted values obtained from the structure images. Although the predicted sheetresistance was slightly different than the real measured values due to atomic defects or imperfections in thecrystals of the Ag-mesh network, it was possible to observe a similar trend between the measured andpredicted sheet resistances with changes in the fractional coverage area of the Ag-mesh network.
