Quantized Field

A secondary quantized field gauge theory with a number of flavors [Formula: see text] has been proposed to describe monolayer graphene. Charge carriers in this graphene model are Majorana pseudo-fermions. Partial unfolding of Dirac bands proceeds from coupling between anti-ordered pseudo-spins and valley currents. Splitting of Dirac cone replicas on Weyl-like node and anti-node leads to polarization effects analogous to graphene doping.

Nanocomposite Fibers

Multi-wall carbon nanotube (MWCNT) based nanocomposite fibers were fabricated using electrospinning method, and their electrical properties were investigated under various loads and temperatures. MWCNTs were initially dispersed into polyvinylpyrrolidone (PVP) and electrospun at various spinning conditions, including DC voltage, pump speed, concentration and distance. When the mechanical load was applied to a film of PVP nanocomposite fibers, the contact resistance, separation between sites and jumping distance of the charge carriers were gradually reduced, thus likely enhancing the electrical conduction. Additionally, as the temperature increased from 20 to 90 °C, the electrical resistance drastically decreased. These behaviors may be a consequence of conductivity and polarization effects of the nanoscale inclusions in the fibers.

The currents of n-p junctions and polarization effects caused by the capture processes of diffusion Si-receivers (detectors) of radiation exposed by ultrasound have been analyzed in this work. It was found that there are local concentrations of impurity atoms with an effective size l>6μm30μm in Si-n-p radiation receivers. They determine the behavior of the signal amplitude in different intervals of electric and temperature fields. It was found that at Е>1500V/cm and T>168K, the efficiency of collecting nonequilibrium charge carriers significantly increases and doublets of spectral α-lines and “humps” disappear at the temperature dependences of the signal amplitude. The main physical processes and mechanisms that determine the appearance of the phenomenon of "polarization" of Si-n-p-detectors were investigated. This phenomenon is caused by the existence of local gold atoms, which arise in the process of manufacturing technology of Si-n-p-receivers and act as effective trapping centers.
