Thermometry and thermal management of carbon nanotube circuits

Abstract

Monitoring of the intrinsic temperature and the thermal management is discussed for the carbon nanotube nano-circuits. The experimental results concerning fabricating and testing of a thermometer able to monitor the intrinsic temperature on nanoscale are reported. We also suggest a model which describes a bi-metal multilayer system able to filter the heat flow, based on separating the electron and phonon components one from another. The bi-metal multilayer structure minimizes the phonon component of the heat flow, while retaining the electronic part. The method allows one to improve the overall performance of the electronic nano-circuits due to minimizing the energy dissipation.

Graphene thermal flux transistor

“…Using localized cooling, 9 one can observe [6][7][8] low-temperature phenomena at room temperature, with no need for bulky and expensive refrigerating equipment. Potentially, these can boost the performance of sensors in external fields, 9 nano-electronic circuits, [10][11][12] and sources of sustainable energy. 13 The dimensions of in-plane nanodevices, such as field effect transistors, quantum dots, and tunnel junctions become comparable to within a few nanometers.…”

On the oscillatory frequency of the carbon nanotube-based nanothermometers

“…Pi and coworkers [33] studied the magnetic nanothermometry utilizing both odd and even harmonics of magnetic nanoparticles under low frequency (f = 117 Hz) ac and dc magnetic elds on the basis of the rst-order Langevin function. Mayle and associates [34] performed investigations on the thermometry of CNT circuits by monitoring the intrinsic temperature and the thermal management for the CNT and nano-circuits. Su et al [35] fabricated Ga-lled MgO and silica nanotubes by a simple onestep method.…”
