Due to the high field enhancement factor and photon-absorption efficiency, carbon nanotubes (CNTs) have been widely used in optically induced field-emission as a cathode. Here, we report vertical carbon nanotube arrays (VCNTAs) that performed as high-density electron sources. A combination of high applied electric field and laser illumination made it possible to modulate the emission with laser pulses. When the bias electric field and laser power density increased, the emission process is sensitive to a power law of the laser intensity, which supports the emission mechanism of optically induced field emission followed by over-the-barrier emission. Furthermore, we determine a polarization dependence that exhibits a cosine behavior, which verifies the high possibility of optically induced field emission.

Field Emission Of Electrons

ABSTRACTWe present the finding of experiments of considerable field emission from the films consisting of nanotube carbon structureson various substrates (Si, quartz, glass): density of emission current was up to 1-3 A/cm2 while electric field was about 100 V/μ. The “reconstruction” and “inversion” of field emission have also been observed after current breakdown.

Films of hexagonal BN (h-BN) codoped with Mg and O atoms were grown on n-type Si and quartz substrates heated at 500 °C by sputtering targets consisting of h-BN and MgO powders. An absorption is seen at a wavelength < 400 nm for h-BN films prepared in an Ar atmosphere. In contrast, films prepared from the target containing 0.25 mol% MgO in an atmosphere of Ar + 1% O2 shows an absorption at a wavelength < 260 nm and an electron field emission at a lower electric field of 3.6 V/μm.
