Web27 de fev. de 2013 · Because of the light mass and strong bonds, the optical-phonon energy is very high in CNTs ℏ ω 0 ~ 160 m e V k B T at 300 K, meaning that these phonons are not thermally populated, which is one of the reasons for the high room-temperature mobilities in CNTs.At small source-drain biases and moderate temperatures the mean … Web11 de out. de 2024 · Due to the phonon boundary inelastic scattering and other phonon transport mechanism, the thermal transport across the ultrathin HfO 2 film below 20 nm may manifest remarkable thickness and temperature dependences for the in-operation HfO 2 film–based nanoscale devices. However, it is still not clear what influence on the thermal …
