Summary: This research focuses on the optimal thickness of indium tin oxide (ITO) as a transparent electrode for near-ultraviolet (NUV) light-emitting diodes (LEDs) based on InGaN/AlGaInN materials. The study investigates ITO thicknesses ranging from 30 to 170 nm and performs annealing processes to determine the best figure of merit (FOM) by balancing transmittance and sheet resistance in the NUV region. Among different thicknesses, an annealed ITO film measuring 110 nm demonstrates the highest FOM with notable characteristics such as 89.0% transmittance at 385 nm, a sheet resistance of 131 Ω/ and a contact resistance of 3.1 x 10(-3) Ω·cm(2). Comparing NUV LEDs using ITO films of various thicknesses, the NUV LED employing ITO with a thickness of 110 nm achieves a significant increase in light output power at 50 mA while maintaining the same forward voltage at 20 mA.

Summary: Interest in transparent conductive materials, particularly graphene and its derivatives, has grown in recent years due to their unique optical and electrical properties. While previous studies have explored replacing indium doped tin oxide with graphene derivatives, a simple and effective method for producing competitive transparent conductive films (TCFs) using graphene has not yet been established. This article introduces a new procedure for fabricating TCFs with high quality, uniformity, and stability, utilizing a combination of drop casting, reduction with triethylenetetramine vapors, and doping with nitric acid. The resulting TCFs exhibit comparable conductivity to existing literature, but with the advantages of simplicity, low cost, scalability, and stability.

Summary: Transparent conductors are crucial for optoelectronic and flexible electronic devices, with oxide/metal/oxide (OMO) multilayer films showing promise as an alternative to traditional transparent conductive oxides (TCOs). However, deposition methods like magnetron sputtering or thermal evaporation can lead to device performance deterioration due to ion bombardment or high temperatures. New techniques, such as reactive plasma deposition (RPD) for high-quality MGZO films and ultrathin Ag films prepared by magnetron sputtering, are being explored to improve conductivity and transmittance in OMO structures.

Summary: AZO/Ag(Ti)/AZO, AZO/Ti/Ag/AZO, and GAZO/Ti/Ag/GAZO multilayer transparent conductive films were deposited on the glass substrate by magnetron sputtering at room temperature. The effects of different Ti power co-sputtered with Ag and Ti as a seed layer for Ag films on the optical, electronic and structural properties of multilayer films were investigated. The influence of the oxide layer and Ti/Ag layer thicknesses on the photoelectric properties of multilayer films were further studied. Experimental results show that Ti as a seed layer changes the growth pattern of Ag. AZO/Ti/Ag/AZO and GAZO/Ti/Ag/GAZO films exhibit high photoelectric performance. Multilayer films with 50 nm GAZO and 12 nm Ti/Ag show low sheet resistance of 5.88 omega sq(-1), high average light transmittance in the visible range of 94.38%, and a figure of merit above 1000 omega(-1). GAZO/Ti/Ag/GAZO films show high transmittance and low resistivity, making them suitable for various photoelectronic applications.
