Electrical conductivity of random metallic nanowire networks: An analytical consideration along with computer simulation [PDF]

open access: yesPhys. Chem. Chem. Phys. 2022. Vol. 24, Iss. 19. P. 11812-11819, 2022
We have proposed an analytical model for the electrical conductivity in random, metallic, nanowire networks. We have mimicked such random nanowire networks as random resistor networks (RRN) produced by the homogeneous, isotropic, and random deposition of conductive zero-width sticks onto an insulating substrate.

Electrical conductivity of nanoring-based transparent conductive films: A mean-field approach [PDF]

open access: yesJournal of Applied Physics 130, 244302 (2021), 2021
We have studied the electrical conductivity of nanoring-based, transparent conductive films, these being promising elements for flexible electronic devices. Both the wire resistance and the junction resistance were taken into account. We have calculated the dependency of the electrical conductivity on the number density of the rings. We have proposed a

Investigation on distribution of electro-thermal coupling fields influenced by HVDC bushing insulation properties

open access: yesFrontiers in Energy Research, 2022
Bushing is an indispensable component in high voltage direct current (HVDC) transmission project. As the main insulating material possesses poor thermal conductivity and negative temperature coefficient (NTC) electrical resistivity, HVDC bushing suffers ...
