Characterization of Sc–O/W(100) Surface as Schottky Emitter: Work Function Change for Activation Processing

Japanese Journal of Applied Physics (2000)

Takashi Kawano Yoshizo Takai Ryuichi Shimizu

To elucidate the electron emissivity of the Sc–O/W(100) Schottky emitter, the Sc–O/W(100) surface, prepared by scandium deposition onto the W(100) surface followed by oxygen exposure and heating at an operating temperature of ∼1400 K, was studied by ion scattering spectroscopy (ISS), Auger electron spectroscopy (AES) and measurement of the relative work function change. The results have revealed that heating of the oxygen adsorbed Sc/W(100) surface leads to the diffusion of the oxygen atoms into the substrate to locate very probably beneath the topmost scandium atoms. This relocation of the oxygen atoms forms an electric double layer, resulting in a significant decrease of the work function. The topmost surface composition of the Sc–O/W(100) system observed by ISS did not change during cooling the sample from ∼1400 K to room temperature under the present conditions. The results of the present work strongly suggest that the surface properties of the Sc–O/W(100) system are very similar to those of the Zr–O/W(100) system at the operating temperature.

Investigation of Corrosion and Hydrogen Entry Behavior under Atmospheric Environment by Real-time Monitoring Techniques

耐水素脆化特性に優れる鋼板の高強度鋼版の開発には,鋼板への水素侵入挙動の明確化が必要である.大気腐食環境下では腐食反応に伴って,鋼板へ水素が侵入するが,水素侵入挙動と腐食挙動の関係,また温湿度や飛来塩分といった環境因子との関係は不明確である.そこで本研究では,水素侵入挙動と腐食挙動の関係およびこれらに与える環境因子の影響を明確化することを目的として,大気暴露環境での水素侵入量と腐食量および環境因子(温度,湿度,付着塩分量)の同時モニタリングを実施した.

Oxygen-nonstoichiometry effect on the superconducting properties of the Sr-free Bi cuprates

Physical review. B, Condensed matter (1990)

Fumio Munakata Takashi Kawano H. Yamauchi Yasuhide Inoue

The effects of oxygen nonstoichiometry on normal-state electrical conduction in and the superconducting properties of ${\mathrm{Bi}}_{2}$${\mathrm{Ca}}_{2.5}$${\mathrm{Nd}}_{0.5}$${\mathrm{Cu}}_{2}$${\mathrm{O}}_{\mathit{y}}$ and ${\mathrm{Bi}}_{2}$${\mathrm{Ca}}_{2.5}$${\mathrm{La}}_{0.25}$${\mathrm{Pr}}_{0.25}$${\mathrm{Cu}}_{2}$${\mathrm{O}}_{\mathit{y}}$ have been investigated. From the temperature dependence of the normal-state resistivity of ${\mathrm{Bi}}_{2}$${\mathrm{Ca}}_{2.5}$${\mathrm{Nd}}_{0.5}$${\mathrm{Cu}}_{2}$${\mathrm{O}}_{\mathit{y}}$, it is speculated that oxygen nonstoichiometry controls the metal-to-semiconductor transition. From the dependence of the high-temperature resistivity on oxygen partial pressure and the thermogravimetric behavior of ${\mathrm{Bi}}_{2}$${\mathrm{Ca}}_{2.5}$${\mathrm{Nd}}_{0.5}$${\mathrm{Cu}}_{2}$${\mathrm{O}}_{\mathit{y}}$ and ${\mathrm{Bi}}_{2}$${\mathrm{Ca}}_{2.5}$${\mathrm{La}}_{0.25}$${\mathrm{Pr}}_{0.25}$${\mathrm{Cu}}_{2}$${\mathrm{O}}_{\mathit{y}}$, it is found that the charge carriers in these cuprates are holes. A long-period modulation is observed by electron diffraction. The modulation is near commensurate with a period equal to 9b.The superconducting properties of ${\mathrm{Bi}}_{2}$${\mathrm{Ca}}_{2.5}$${\mathrm{Nd}}_{0.5}$${\mathrm{Cu}}_{2}$${\mathrm{O}}_{\mathit{y}}$ and ${\mathrm{Bi}}_{2}$${\mathrm{Ca}}_{2.5}$${\mathrm{La}}_{0.25}$${\mathrm{Pr}}_{0.25}$${\mathrm{Cu}}_{2}$${\mathrm{O}}_{\mathit{y}}$ are dependent on oxygen partial pressure during sintering, but the modulation period remains unchanged. Although the Cu oxidation states in both ${\mathrm{Bi}}_{2}$${\mathrm{Ca}}_{2.5}$${\mathrm{Nd}}_{0.5}$${\mathrm{Cu}}_{2}$${\mathrm{O}}_{\mathit{y}}$ and ${\mathrm{Bi}}_{2}$${\mathrm{Ca}}_{2.5}$${\mathrm{La}}_{0.25}$${\mathrm{Pr}}_{0.25}$${\mathrm{Cu}}_{2}$${\mathrm{O}}_{\mathit{y}}$, which are sintered at ${\mathit{P}}_{\mathrm{O}2}$=1 atm, are the same, being equal to 2.08, their superconducting properties are found to be different. This may suggest that the effective valences of Cu and O are different from the conventional integer values because of charge transfer between Cu and O.

Study on Zr–Si/W(100) Surface at High Temperatures by Combined Surface Analysis Techniques

Japanese Journal of Applied Physics (1998)

Takashi Kawano Yoshihide Kimura Ryuichi Shimizu

The basic mechanism of electron emissivity of a Zr–Si/W(100) surface, which has attracted much attention as a thermal field emitter for practical use, was studied by Auger electron spectroscopy, ion scattering spectroscopy and work function measurements. The results show that the topmost atomic layer consists of Zr and Si at operating conditions (∼1300 K, 10 -9 Torr), the work function of which is slightly reduced by an order of half an eV from that of a clean W(100) surface.
