A high‐resolution energy analyzer system for measuring energy distribution of field‐emitted charged particles has been developed. For high resolution to be achieved, an electrostatic bipotential lens for deceleration of particles was newly designed by using an ion optics simulation software (SIMION 3D) and coupled with the cylindrical electrostatic spectrometer developed by C. Oshima et al. To evaluate...
A 90° sector type spin rotator was developed for measurement of the z-direction component of a spin polarization, which is parallel to the emitter axis. The rotator enables us to measure all components of electron spins field-emitted from a single crystalline magnetite. In-plane component of spin polarization dominated of field-emitted electrons from single crystalline magnetite whisker, thus it is...
The author developed a method to grow CNTs selectively onto an apex of W-tip using "selective etching" method. Here the author reports that this method is also valid to control the number of CNTs at the W-tip.
In this study, the CNT growth by the RF-PECVD is sensitive to the granulation condition of catalyst film. It is expected that further precise control of the granulation of catalyst film enables further improvement of controllability of CNT growth that gives better FE characteristics.
