Fabrication of InGaN thin-film transistors using pulsed sputtering deposition

We report the first demonstration of operational InGaN-based thin-film transistors (TFTs) on glass substrates. The key to our success was coating the glass substrate with a thin amorphous layer of HfO2, which enabled a highly c-axis-oriented growth of InGaN films using pulsed sputtering deposition. The electrical characteristics of the thin films were controlled easily by varying their In conte...

Fabrication of Thin Palladium-Silver Alloy Film by Using Electroplating Technique

A thin Pd-Ag alloy film, which will be applied to fabricate membranes for hydrogen separation, was successfully deposited using an electroplating technique. The plating solution for the formation of a thin Ag-rich Ag-Pd film for electric contact consisted of PdCl2, AgNO3, HBr, and HNO2. An improvement of the electrolytic bath was achieved by a pH control, which was kept constant at 6.6 and by t...

Dry and Wet Wear Characteristic of TiO2 Thin Film Prepared by Magnetic Sputtering in Ringer Solution

In this research, a thin film of TiO2 was applied on AZ91D using the method of magnetic sputtering. Microstructure investigations were done using field emission scanning electron microscope (FESEM) and X-ray diffraction (XRD). Wear resistance for the coating was investigated using the pin on the disk in the form of dry and in the Ringer's solution. After this test, the worn surface of the sampl...

Fabrication of high-quality single-crystal Cu thin films using radio-frequency sputtering

Copper (Cu) thin films have been widely used as electrodes and interconnection wires in integrated electronic circuits, and more recently as substrates for the synthesis of graphene. However, the ultra-high vacuum processes required for high-quality Cu film fabrication, such as molecular beam epitaxy (MBE), restricts mass production with low cost. In this work, we demonstrated high-quality Cu t...
