– We investigated the pinning of flux lines in a superconducting film by a regular array of magnetic antidots. The sample consists of a Co/Pt multilayer with perpendicular magnetic anisotropy in which a regular pattern of submicron holes is introduced and which is covered by a type-II superconducting Pb film. The resulting ferromagnetic/superconducting heterostructure shows a pronounced asymmet...

The progress in high technology has led to the wide use of thin film transistor-liquid crystal display (TFTLCD). The evolution of the manufacturing technology of TFT-LCD keeps increasing the size of TFT-LCD since a larger TFT-LCD allows a larger display application and an improved productivity. However, as the size of TFT-LCD increases, the size of TFT-array substrates and color filter substrat...

in this paper a chemical deposition procedure for the preparation of lead sulfide thin film ispresented. the details of the preparation method are described. the influence of hydrazine hydrate onthe microstructure and deposition rate of lead sulfide thin film has been investigated. the concentrationof the lead ions in the deposition bath decreases more slowly when the hydrazine hydrate is added...

Enhancement of conductivity and/or superconductivity has been found in YBa2CuaO~ thin films after illumination with visible light. 1-'t This persistent photoinduced conductivity (PPC) and photoinduced superconductivity (PPS) is maximum for deoxygenated samples and an insulating YBa2Cu:30~ thin film can even become superconducting by illumination, a In bicrystal grain boundary Josephson junction...

Superconducting germanium films are an intriguing material for possible applications in fields such as cryogenic electronics and quantum bits. Recently, there has been a great deal of progress hyperdoping Ga doped Ge using ion implantation. Thin film growth would be advantageous, allowing homoepitaxy undoped opening possibilities vertical Josephson junctions. Here, we present our studies on the...

We have studied the local transport properties in an epitaxial YBa2Cu3O7 x (YBCO) film on LaAlO3 (LAO) using variable temperature scanning laser microscope (VTSLM) near the superconducting transition. A map of the superconducting transition temperature ðT c Þ is generated from a series of VTSLM images. The map of T c indicates there are inhomogeneities in the film large enough to create nonunif...

Transition metal oxides display various electronic and magnetic phases such as high-temperature superconductivity. Controlling such exotic properties by applying an external field is one of the biggest continuous challenges in condensed matter physics. Here, we demonstrate clear superconductor-insulator transition of LiTi2O4 films induced by Li-ion electrochemical reaction. A compact electroche...
