New Materials for Transparent Electrodes

Flexible Transparent Electrodes Formed from Template‐Patterned Thin‐Film Silver

“…Owing to the nonmonotonic dependence of $$\bar{T}$$ on d Ag , the curves deviate from the usual trade‐off behavior for TEs, in which a reduction in $${\mathcal{R}}_s$$ always comes at the expense of a drop in $$\bar{T}$$. [ 40 ] For the case of the p‐OA/Ag samples, conventional trade‐off behavior is observed for very thin silver coatings up to ≈5 nm, with $$\bar{T}$$ and $${\mathcal{R}}_s$$ falling from 87.3% and 3.3 × 10 10 Ω sq −1 at d Ag = 0 nm to 44.1% and 1.4 × 10 8 Ω sq −1 at d Ag = 5 nm. However, further increases in d Ag up to 11 nm can be seen to cause a substantial increase in $$\bar{T}$$ to 60.2% accompanied by a sharp decrease in $${\mathcal{R}}_s$$ to 43 Ω sq −1 .…”
