Kinetics of DyNi2 film growth by electrochemical implantation

Electrochemical implantation was performed at Ni electrodes to form DyNi₂ films at 0.55 V (vs. Li⁺/Li), 0.62 V, and 0.70 V for 0.5-5.0 h in a molten LiCl-KCl-DyCl₃ (0.50 mol%) system at 700 K. It was found that the DyNi₂ films grew linearly with time with coulomb efficiency of about 100%. The obtained growth rates were higher at more negative potentials, i.e., 0.47 μm min⁻¹ at 0.55 V, 0.32 μm min⁻¹ at 0.62 V, and 0.14 μm min⁻¹ at 0.70 V. On the analogy of the metal oxide growth, the observed rapid and linear growth of DyNi₂ films may be explained by the existence of the outer and inner DyNi₂ layers.

Electron transport in InGaO3(ZnO)m (m=integer) studied using single-crystalline thin films and transparent MISFETs

We have investigated the characteristics of transparent metal-insulator-semiconductor field-effect transistors (MISFETs) fabricated using InGaO₃(ZnO)_m (m=integer) single-crystalline thin films as n-channel layers and amorphous alumina as gate insulator films. The MISFETs exhibit good characteristics such as insensitivity to visible light illumination, off-current as low as ∼1 nA with a positive threshold voltage of ∼3 V and on/off current ratio of 10⁵. The field-effect mobility increased from ∼1 to ∼10 cm² (V s)⁻¹ as the m-value increased. Room temperature Hall mobility also increased. However, unexpectedly these values were lower than the field-effect mobility. It is explained by existence of shallow localized state in the homologous compounds.
