Thermoradiative Cell Equivalent Circuit Model

IEEE Transactions on Electron Devices, 2021
Thermoradiative cells provide a means of electricity generation through direct transfer of energy from heat flux at the cell to radiation from the cell to a colder ambient. While thermodynamic limits and detailed models have been developed for thermoradiative cells, intuitive models to guide the development of thermoradiative cells and associated ...

Equivalent Circuit Model of MWCNT Nanointerconnects

2008 8th IEEE Conference on Nanotechnology, 2008
The transmission line model of a multi-wall carbon nanotube interconnect is formulated in the time domain, considering the statistical and the deterministic model of the conducting channel number in each shell. The equivalent per- unit-length circuit of the interconnect is derived for possible implementation in commercial circuit solvers.
