    To determine the thermodynamic temperature of a solid surface from the electron energy distribution measured by photoelectron spectroscopy, it is necessary to accurately evaluate the energy broadening of the photoelectron spectrum and investigate its temperature dependence. Broadening functions in the photoelectron spectrum of Au(110)’s surface near the Fermi level were estimated successfully using the relationship between the Fourier transform and the convolution integral. The Fourier transform could simultaneously reduce the noise of the spectrum when the broadening function was derived. The derived function was in the form of a Gaussian, whose width depended on the thermodynamic temperature of the sample and became broader at higher temperatures. The results contribute to improve accuracy of the determination of thermodynamic temperature from the photoelectron spectrum and provide useful information on the temperature dependence of electron scattering in photoelectron emission processes.

    We devised a new method of determining the temperatures of materials with their electron-energy distributions. The Fermi–Dirac distribution convoluted with a linear combination of Gaussian and Lorentzian distributions was fitted to the photoelectron spectrum measured for the Au(110) single-crystal surface at liquid N<inf>2</inf>-cooled temperature. The fitting successfully determined the surface-local thermodynamic temperature and the energy resolution simultaneously from the photoelectron spectrum, without any preliminary results of other measurements. The determined thermodynamic temperature was 99 ± 2.1 K, which was in good agreement with the reference temperature of 98.5 ± 0.5 K measured using a silicon diode sensor attached to the sample holder.

    A novel retarding type electron energy analyzer implementing an electrostatic lens system to achieve a high energy resolution sufficient to measure thermodynamic temperature has been investigated based on the electron trajectory analysis. The energy resolution of the analyzer depends linearly on the retarding energy with a modulus of 0.05 %. The voltages to be applied to the electrodes in the analyzer are found to be controllable linearly against the retarding voltage. The analyzer has threshold energies, whose effect can be excluded in practical measurements.

    ナノサイズの物質には固有の量子サイズ効果があり,固体中では得られない新しい電気的あるいは磁気的特性があり,近年,大きな関心が寄せられている。ナノグラファイトはナノサイズのグラフィン(グラファイト単一層)が積層してできているため,フラーレンやナノチューブと異なり,炭素原子の周端(Edge)構造があり,それら周端がこの物質の特異な電子特性と磁気特性をもたらす重要な役割を果たしている。この物質を生かした材料科学の発展のためには,ナノグラフィンの電子構造の詳細な知識を得ること,そして,その電子状態がどのように周端構造に支配されているかを明らかにすることが重要である。周端の領域で考えられる電子状態には,炭素間の結合におけるσ軌道とπ軌道に起因した2種類がある。ナノグラフィンリボンの理論計算では,周端に局在したπバンドが,この物質の電子スピンの新しい起源であることを示す。
    ナノグラファイトの周端は他の原子に化学吸着され易い。したがって,周端の化学的な変化がナノグラフィンの電子構造にどの程度影響するか知ることは重要である。この情報は,この物質の新奇な特性の起源を探知するためだけではなく,この物質の化学的変化を制御するためにも有効である。本研究では,Pt(111)表面上に生成された60Å程度の平均直径のナノグラフィンの電子構造における重水素の終端効果における電子状態の変化を3光子電子分光および紫外光電子分光で測定した。その結果,ナノグラフィンの重水素による終端が2つのナノグラフィンの電子状態-σ^*電子状態とπ電子状態-にどのように影響するかを示した。ナノグラフィンはサイズが十分に大きいため,エネルギーと分散関係において,固体グラファイトと同様の性質を示しているが,2つの電子状態は重水素による終端に対し強く影響をうけることがわかった。特に,σ^*電子状態はπ電子状態に比べ,周端の化学的変化に非常に敏感であることがわかった。
