“…Therefore, most field emission devices require a triode structure having a gate electrode that controls the emission current. In addition, field electron emitters have been known to be very susceptible to a poor vacuum as compared with conventional hot cathodes [30,41,42]. The vacuum level of the sealed vessel can easily get worse due to outgassing from the inner materials.…”

Highly reliable field electron emitters were developed using a formulation for reproducible damage-free carbon nanotube (CNT) composite pastes with optimal inorganic fillers and a ball-milling method. We carefully controlled the ball-milling sequence and time to avoid any damage to the CNTs, which incorporated fillers that were fully dispersed as paste constituents. The field electron emitters fabricated by printing the CNT pastes were found to exhibit almost perfect adhesion of the CNT emitters to the cathode, along with good uniformity and reproducibility. A high field enhancement factor of around 10,000 was achieved from the CNT field emitters developed. By selecting nano-sized metal alloys and oxides and using the same formulation sequence, we also developed reliable field emitters that could survive high-temperature post processing. These field emitters had high durability to post vacuum annealing at 950 °C, guaranteeing survival of the brazing process used in the sealing of field emission x-ray tubes. We evaluated the field emitters in a triode configuration in the harsh environment of a tiny vacuum-sealed vessel and observed very reliable operation for 30 h at a high current density of 350 mA cm(-2). The CNT pastes and related field emitters that were developed could be usefully applied in reliable field emission devices.

“…Because a recent report demonstrates that a single ZnO NW shows the quick and high sensitive response at room temperature, 2) our smart gas sensor is to be operated at room temperature. The low-frequency noise of a singlecrystalline ZnO NW synthesized by the vapor-liquid-solid (VLS) process 7) is also analyzed at room temperature and ambient conditions. The sensitivity and noise property at various temperatures are under investigation.…”

Temporally and spectrally resolved (90 2 harmonic emission and stimulated Raman scattering has been observed from thin foils irradiated by double pulse 010.53 pn laser light. Asymmetric W O 2 spectrum from the prepulse can he explained by the spectral model including ?U,-plasmon-photon coupling and the effects of plasmon refraction. The Raman signal from the main pulse is broad corresponding ;o densities up to O.?Zn, for the Raman process. An anomalous red shift -1000 . A from the (90 2 frequency observed during the main pulse indicates inverse resonance absorption of the Raman-plasmons. because the red shift is too large to be explained b j the ?to,-insiabilit~.
