Abstract
The potential applications of advanced electronic materials in large-area, printable, and flexible electronics have generated significant interest. However, creating high-performance, low-voltage thin-film transistors (TFTs) for these applications remains difficult due to a lack of advanced gate dielectric and semiconductor materials that meet both ease-of-fabrication requirements and high electrical performance. In.....

Abstract
Improving solar energy conversion efficiency and reducing energy loss have become critical issues in recent decades. Photoelectrochemical (PEC) water splitting provides an ideal method for solar energy harvesting and is a key factor in decreasing the use of fossil fuels. Thus, it is extremely important to identify cost-effective, highly active,.....

Abstract
In this study, we demonstrate high-performance optical wavelength-selective organic thin-film transistors (TFTs) that incorporate heterogeneous organic semiconductor materials, poly(3-hexylthiophene) (P3HT) and 6,13-bis(triisopropylsilylethynyl) pentacene (TIPS-pentacene). The electrical characteristics of the fabricated transistors were analyzed in the dark to determine how the P3HT:TIPS-pentacene ratio of the semiconductor affected the performance of the.....

Abstract
This study evaluated changes in delta-ferrite content depending on the preheating of AISI 316L stainless steel. We also determined the reasons for the variation in delta-ferrite content, which affects corrosion resistance. Changes in delta-ferrite content after preheating was confirmed using a Feritscope, and the microstructure was analyzed using optical microscopy.....

Abstract
To attain high life standards, it is important to develop high-performance non-toxic gas sensors for public safety, environmental pollutant control, industrial processes, etc. Because reports on single element semiconductor-coated semiconducting metal oxides for sensing applications are rare, we synthesized SnO

Abstract
This article details how effectively dicing damage of silicon wafers can be mechanically minimized by appropriate laser-induced groove formation prior to wafer separation. Various laser dicing factors, such as the laser-control power, the scan rate and the scan number of the laser beam, were estimated to determine the optimum groove.....

Abstract
Memristors have been extensively investigated as the fourth fundamental circuit element. Titanium oxide is a common material used to fabricate memristors. In this paper, we investigated the influence of the thickness of the oxide active layer on the Al/TiO2-x/TiO2/heavily doped electrode memristor architecture. An insulating TiO2 thin-film was deposited using.....

Abstract
The shadowing effect is one of the most urgent issues yet to be solved in high-volume manufacturing using extreme ultraviolet lithography (EUVL). Many studies have been conducted to mitigate the unexpected results caused by shadowing effects. The simplest way to mitigate the shadowing effect is to reduce the thickness of...

Abstract
This work details how the sawing velocity influences the chipping damage of semiconductor wafers with different thicknesses during wafer separation. The experimental result shows that at a sawing velocity higher than 60000 rpm, in thinner wafers the magnitude of chipping damage more strongly depends on the revolving velocity of the.....
