Development of the α-IGZO/Ag/α-IGZO Triple-Layer Structure Films for the Application of Transparent Electrode

Abstract: We investigated the structural, optical, and electrical properties of amorphous IGZO/silver/amorphous IGZO (α-IGZO/Ag/α-IGZO) triple-layer structures that were deposited at room temperature on Eagle XG glass and flexible polyethylene terephthalate substrates through the sputtering method. Thin Ag layers with different thicknesses were inserted between two IGZO layers to form a triple-layer structure. Ag was used because of its lower absorption and resistivity. Field emission scanning electron microscopy measurements of the triple-layer structures revealed that the thicknesses of the Ag layers ranged from 13 to 41 nm. The thickness of the Ag layer had a large effect on the electrical and optical properties of the electrodes. The optimum thickness of the Ag metal thin film could be evaluated according to the optical transmittance, electrical conductivity, and figure of merit of the electrode. This study demonstrates that the α-IGZO/Ag/α-IGZO triple-layer transparent electrode can be fabricated with low sheet resistance (4.2 Ω/□) and high optical transmittance (88.1%) at room temperature without postannealing processing on the deposited thin films.

Optical wavelength/spatial coding system based on quadratic congruence code matrices

Abstract: This letter proposes a wavelength/spatial optical code-division multiple-access system based on quadratic congruence code matrices (QCCM). According to the in-phase cross-correlation of the QCCM, multiple-access interference can be fully eliminated by using balanced photodetectors (PDs). Moreover, this proposal provides greater signal power than does the modified quadratic congruence (MQC) coding system. Compared with the maximal-area matrices (M-matrices) and MQC coding system, the simulated results indicate that the proposal can remarkably improve the system performance in the receiver PDs
