We have measured spectra of the light emission from the frictional contact between the pin of natural diamond, synthetic fused silica, MgO, or NaCl and the disk of quartz or synthetic sapphire in a vacuum in the wavelength range between 380 and 10...

We have performed a quartz crystal microbalance (QCM) experiment for Kr films adsorbed on a single-crystalline graphite substrate at various temperatures. The substrate enables us to study the oscillation direction dependence of the sliding fricti...
The pressure dependence of the electron stimulated desorption (ESD) ions were investigated by the quadrupole mass spectrometer with a Bessel-box type energy analyzer. The mass spectra of the ESD ions were measured under introduction of...
The isotherms and the isobars of krypton and xenon physisorbed on a silver single crystal surface were investigated by ellipsometric observation of the amount of adsorption. It was found that they showed a hysteresis in an adsorption-d...
The deviation of the sensitivity factors for the axial-symmetric transmission gauge (AT gauge) were examined and compared with those for the B-A gauges and the extractor gauges. The calibrations were performed against nitrogen. The dev...
低温表面上に物理吸着した水素の密度を測定するために、電子励起脱離(ESD)法を用いた。脱離したイオンを飛行時間測定法(TOF : time of flight)を用いて質量分析し、H+の収量から水素の吸着密度を決定し、その吸着等温線を求める。本研究では、広い温度範囲での吸着等温線を求めることを目的とする。また、吸着平衡に近づく過渡状態の観測から物理吸着する水素の平均滞在時間を測定する。
<p>Surface science had its beginning at the dawn of the human civilization and vacuum science in the 17th century. Collaboration between them has begun in the late 19th century and has grown in close manner in the field of sc...
