Abstract
The technology of nanowhiskers growth in the scanning electron microscope vacuum chamber have been applied for the creation of 2D and 3D carbon wireframe nanosystems (CWNS). The probability of electron transition has been calculated within simple quantum graph (quantum network) model. For the purpose of research of CWNS electron state density investigation it is proposed to grow CWNS on the tungsten tip apex and to measure current–voltage characteristics I(V) of Au plate – vacuum gap – CWNS W tip tunneling junction in the ultra high vacuum scanning tunneling microscope. Experiments show that proposed methodic approach gives adequate I(V) dependencies for metallic and semiconductor nanowhiskers at the room temperature. For detection of the peculiarities at I(V) tunneling junction characteristics caused by quantum graphs it is required to carry out measurements at low temperature conditions.
