Abbreviated Series Title o improve siliconfield emitters, an amorphous-carbon-nitride (a-CN) coating was applied by helical resonator plasma-enhanced chemical vapor deposition. By this process, a-CN was very uniformly coated on silicon tips without any damage. Microstructural and electrical investigation of the silicon and a-CN coated field emitters were performed. a-CN coating lowered turn-on voltage and increased emission current. Negative electron affinity of carbon nitride is suggested for enhancing emission current.

Bakhtizin, R. Z.; Valeev, V. G. Microroughness field emission electron energy distribution and electron-phonon interaction spectroscopy near the metal surface Journal Article 1988 Physica Status Solidi A Phys. Stat. Sol. A 108 1 251-255 Field Emission Field electron emission is considered from microtips on the metal surface. The possibility is shown of field emission spectroscopy of electron-phonon interaction near the emitting surface and the influence is studied of an increase in the surface potential barrier transparency by application of a weak high-frequency field altering the character of the field electron energy distribution in such a system. no 4012

Sci. 231 1-2 135-138 Field Ion Microscopy Laser-stimulated processes of constant field evaporation of surface atoms are described. It is shown that under certain conditions the application of a weak alternating field may enhance ion tunneling and result in a significant increase in ion current. The paper offers a numerical estimation of the expected results of such an experiment. no 4324

Anderson, C. R.; Lee, R. N. Accurate measurements of electron energies by field-emitter referencing Journal Article 1984 Journal of Electron Spectroscopy and Related Phenomena J. Electron Spectrosc. Relat. Phenom. 34 2 173-198 A new technique of electron Spectroscopy is described in which a standard electron spectrometer is used to compare the electron energy to be measured with the energies of electrons from a field-emitter reference source. Since the reference electrons are emitted at the Fermi level of the emitter tip, their total energy can be accurately measured with a high precision digital voltmeter. The measurements are automatically referenced to the absolute scale of energies and the need for calibration standards is eliminated. The application of the technique to X-ray photoelectron Spectroscopy (XPS) is described. Detailed analysis shows that the uncertainty in the field-emitter referenced XPS measurements is ± 0.06 electron volts. no 8497

Lee, S.-W.; Yeh, J.-W. Superplasticity of 5083 alloys with Zr and Mn additions produced by reciprocating extrusion Journal Article 2007 Materials Science and Engineering: A 460-461 409-419 Aluminum alloys; Extrusion; Superplasticity In this study, 5083 aluminum alloys modified with grain refiner, 0.25% Zr and 0.46% Mn, were processed by reciprocating extrusion to yield high-strain-rate superplasticity above 400 [degree sign]C and superior room-temperature mechanical properties. Without any prior homogenization treatment, 10 extrusion passes could give the cast billets an equiaxed grain structure with a grain size of about 4.5 [mu]m and a subgrain size about 0.2 [mu]m, and a uniform distribution of fine inclusions and dispersoids in the matrix. The fine-grained structure was stable up to 525 [degree sign]C, giving the alloy a high-strain-rate and low-stress superplasticity over a wide operating temperature of 400-500 [degree sign]C. In the tensile test at 500 [degree sign]C, a maximum elongation of 1013% and a low flow stress of 7.7 MPa at 5 x 10-2 s-1 were achieved. The apparent and true activation energies for low temperatures (300-400 [degree sign]C) without high-strain-rate superplasticity were 220.6 and 208 kJ/mol, respectively, whereas those at high temperatures (400-500 [degree sign]C) were 88.4 and 98.7 kJ/mol, respectively. Further analysis confirms that grain boundary sliding is the dominant mechanism over the high-strain-rate region from 1 x 10-2 to 5 x 10-1 s-1 at 500 [degree sign]C, and power-law breakdown mechanism occurs over the strain rate from 5 x 10-4 to 1 x 10-2 s-1 at 300 [degree sign]C. The high-strain-rate superplasticity was more strongly enhanced by Zr addition than addition of Cr and Mn. Two enhancing mechanisms for the maximum superplastic elongation and the optimum strain rate are proposed. This study concludes that the effectiveness of Zr is caused by the fineness and the coherency of Zr-rich dispersoids in the matrix. no NU @ karnesky @ 9637
