“…A theoretical study by Chen et al was in agreement with Scheibner et al when they showed the thermally rectifying effect was dependent on the coupling between the quantum dot and the electrode [94]. In 2009 Ruokola et al investigated thermal rectification in nonlinear quantum thermal circuits where the coupling between the baths and the nonlinear resonator circuit were mutual inductances [95]. Their results showed levels of rectification up to 0.11.…”

Thermal rectification is a phenomenon in which thermal transport along a specific axis is dependent upon the sign of the temperature gradient or heat current. This phenomenon offers improved thermal management of electronics as size scales continue to decrease and new technologies emerge by having directions of preferred thermal transport. For most applications where thermally rectifying materials could be of use they would need to exhibit one direction with high thermal conductivity to allow for efficient transport of heat from heat generating components to a sink and one direction with low conductivity to insulate the temperature and heat flux sensitive components. In the process of understanding and developing these materials multiple mechanisms have been found which produce thermally rectifying behavior and much work has been and is being done to improve our understanding of the mechanisms and how these mechanisms can be used with our improved ability to fabricate at the nanoscale to produce efficient materials which have high levels of thermal rectification.

“…Heat transfer due to photons in nanoscale circuits has been studied theoretically [157,158,159,160,161,162,163] as well as been experimentally observed [164,165]. Here, we present two different examples of photon harvesting.…”

Abstract. We review recent theoretical work on thermoelectric energy harvesting in multi-terminal quantum-dot setups. We first discuss several examples of nanoscale heat engines based on Coulomb-coupled conductors. In particular, we focus on quantum dots in the Coulomb-blockade regime, chaotic cavities and resonant tunneling through quantum dots and wells. We then turn towards quantum-dot heat engines that are driven by bosonic degrees of freedom such as phonons, magnons and microwave photons. These systems provide interesting connections to spin caloritronics and circuit quantum electrodynamics.

“…[14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] Because the vibrations inducing the structural deformation have a lower frequency than thermal phonons and propagate ballistically in comparison with them, we need an elastic-wave rectifier [31][32][33][34][35][36] rather than the thermal rectifier in order to achieve the expected performance of the nano-device, NEMS and so on.…”

Fluids 22, 052003 (2010) Additional information on J. Appl. Phys. We propose a rectifier of elastic waves in a thin plate, which is made of an elastically isotropic material containing a periodic array of triangular holes as scatterers, and demonstrate numerically that it works both for the symmetric and anti-symmetric Lamb waves as well as shear horizontal waves. The rectification is caused by the geometric effects on wave scattering due to the asymmetric scatterers, while the interplay between the mode conversion and interference effects among the scattered waves owing to the periodic arrangement of scatterers complicates it. The mechanism makes it possible to rectify the typical elastic waves in the system above the threshold frequency corresponding to the wavelength equivalent to the periodicity of scatterers.
