โœฆ Synopsis

The carbon nanotubes (CNTs) doped MgB 2 bulks were sintered in the 5 T pulsed magnetic field at 800 ยฐC for 30 min. The critical temperature (T c ) is 36.3 K, a little higher than that of the bulks sintered without magnetic field, 35.7 K. The critical current density (J c ) shows anisotropy in high measurement magnetic field. The J c at 20 K increase in high field region when the measurement magnetic field is perpendicular to the sintering magnetic field.

Effects of ion impinging on the microstructure and field electron emission properties of screen-printed carbon nanotube films were investigated. We observed that the plasma treatment modified the microstructure of CNTs along with the remarkable increase of emission site density. With the prolongatio
