New carbon cone nanotip for use in a highly coherent cold field emission electron microscope
A new cathode for cold-field emission gun using a pyrolytic carbon-cone supported onto a carbon nanotube as the electron emitting tip has been developped. This tip was mounted in a TEM using a FIB based method, and the brightness measured under real operating conditions is 5 times better than obtained with a standard tungsten tip. Its use overcomes the many technical difficulties which have dog...
متن کاملNanotip electron gun for the scanning electron microscope.
Experimental nanotips have shown significant improvement in the resolution performance of a cold field emission scanning electron microscope (SEM). Nanotip electron sources are very sharp electron emitter tips used as a replacement for the conventional tungsten field emission (FE) electron sources. Nanotips offer higher brightness and smaller electron source size. An electron microscope equippe...
متن کاملNew Method for Multiple Immunodetection on Resin Ultrathin Section in the Field Emission Scanning Electron Microscope
Localization of a specific protein within the cell ultrastructure in high resolution is based on a specific bond between the molecule of interest (antigen) and an antibody conjugated to an electron dense nanoparticle clearly visible in consecutive observation in the electron microscope. Colloidal gold nanoparticles are usually used as the label. Diameter of the nanoparticle must be small enough...
متن کاملField emission of individual carbon nanotubes in the scanning electron microscope.
The field emission of individual multiwall carbon nanotubes grown by chemical vapor deposition was measured in a scanning electron microscope. By using a sharp anode, we were able to select one nanotube for measurements in carefully controlled conditions. Single nanotubes follow the Fowler-Nordheim law, and the dependence of the field enhancement with interelectrode distance and nanotube radius...
متن کاملField emission from individual multiwalled carbon nanotubes prepared in an electron microscope.
Individual multiwalled carbon nanotube field emitters were prepared in a scanning electron microscope. The angular current density, energy spectra, and the emission stability of the field-emitted electrons were measured. An estimate of the electron source brightness was extracted from the measurements. The results show that carbon nanotubes are promising candidates to replace existing sources i...
