Electron emission measurements were conducted on individual carbon nanotubes. The nanotubes had a closed end and their surfaces were thoroughly cleaned. It is shown conclusively that individual carbon nanotube electron emitters indeed exhibit Fowler–Nordheim behavior and have a work function of 5.1±0.1 eV for the nanotubes under investigation, which had diameters of 1.4 and 4.9 nm.

    We report procedure with use of self-assembled silicon carbide (SiC) nanomasks for preparation of ultrahigh-density Si nanotips. Si nanotips with SiC apex may be firstly prepared in a CH4/H2 plasma treatment and in a subsequent H2 plasma etching a SiC apex may be converted into an amorphous...

    The secondary electron emission of the tube bodies of single-walled carbon nanotubes is found to be ultrahigh and comparable with that of diamond, when the nanotubes are connected with electron reservoir. Both of semiconducting and metallic nanotubes possess this property.

    We have developed a silicon tip, fabricated by highly selective anisotropic dry etching using oxygen precipitates (SiOx, x∼2) in a silicon substrate as the etching mask. The gated field-emission device with the single silicon tip was characterized, under a pressure of 10-8-Torr range after...

    Two-dimensional SnO2 nanograsses were synthesized on single-crystal Si substrates by catalyst-assisted thermal evaporation. The photoluminescence spectra from the products revealed multipeaks consistent with previous reports, with the exception of a new peak at 574 nm. The large field emission...

    Clarification on electron emission mechanism of diamond is one essential approach to realize the clear vision of vacuum nanoelectronics. Electric field of less than 5 V/μm is enough to extract electrons from diamond, whereas field of one to two orders of magnitude higher is needed to extract...

    Most carbon nanotubes consist of a helical arrangement of carbon atoms. Consequently, tubes of left- and right-handed configuration should exist. Their chiral character is recovered in the magnetoresistance as an odd power contribution in the magnetic field and the current, i.e., depending on...

    We report on the preparation and field-emission properties of vertically aligned conductive IrO[sub 2] nanorods. The unique geometrical features of IrO[sub 2] nanorods, including nanosized structure and self-assembled sharp tip, exhibit a strong effect on field enhancement (β∼40 000),...

    Spatially resolved electron field emission experiments on oxidized highly phosphorus-doped homoepitaxial diamond (111) were applied at room temperature. The diamond layer shows hopping conductivity. Field emission properties have three distinct regions. We attribute the variation in emission...
