“…This phenomenon can be better applied in 2D materials since it is easier to construct asymmetric structures than in 1D materials. By structure regulation, 2D materials can be tailored to a more suitable structure to maximise the thermal rectification effect from both theoretical and experimental works, as reviewed by Zhao 242 et al…”

“…The best way to achieve thermal rectification at nanoscales is to exploit the nonlinear dynamics present in anharmonic lattice structures in combination with the inherent asymmetric structure of the system [8]. Specifically, asymmetric structures can be roughly classified [87] into asymmetric geometry [11,37,[88][89][90][91], asymmetric doping and defects structures [12,92,93], asymmetric interfacial structures [13,14,94,95], and other structures [96][97][98].…”

Phonons are the quantum mechanical descriptions of vibrational modes that manifest themselves in many physical properties of condensed matter systems. As the size of electronic devices continues to decrease below mean free paths of acoustic phonons, the engineering of phonon spectra at the nanoscale becomes an important topic. Phonon manipulation allows for active control and management of heat flow, enabling functions such as regulated heat transport. At the same time, phonon transmission, as a novel signal transmission method, holds great potential to revolutionize modern industry like microelectronics technology, and boasts wide-ranging applications. Unlike fermions such as electrons, polarity regulation is difficult to act on phonons as bosons, making the development of effective phonon modulation methods a daunting task. This work reviews the development of phonon engineering and strategies of phonon manipulation at different scales, reports the latest research progress of nanophononic devices such as thermal rectifiers, thermal transistors, thermal memories, and thermoelectric devices, and analyzes the phonon transport mechanisms involved. Lastly, we survey feasible perspectives and research directions of phonon engineering. Thermoelectric analogies, external field regulation, and acousto-optic co-optimization are expected to become future research hotspots.

“…The advance in the field has been very impressive since only a few years elapsed from the the first theoretical proposal involving a structure consisting of coupled one-dimensional (1D) anharmonic oscillator lattices [7] to the first successful experimental implementations by means of asymmetric nanotube structures [8], of coupled cobalt oxides with different thermal conductivities [9], and polycrystalline samples with asymmetric shape [10]. Furthermore, benefiting from the development of nano-and micro-technology in modeling and nanofabrication, it is now possible to engage in both experimental and theoretical research of nanostructures, such as carbon nanotube bundles [11] and asymmetric 2D graphene monolayers [12,13], with a potential to develop practical devices for intelligent thermal management, novel thermal transistors, and energy harvesting, among others.…”

In this work we perform a systematic analysis of various structural parameters that have influence on the thermal rectification effect, i.e. asymmetrical heat flow, and the negative differential thermal resistance -reduction of the heat flux as the applied thermal bias is increased-present in a one-dimensional, segmented mass-graded system consisting of a coupled nearest-neighbor harmonic oscillator lattice (ballistic spacer) and two diffusive leads (modeled by a substrate potential) attached to the lattice at both boundaries. At variance with previous works, we consider the size of the spacer as smaller than that of the leads. Also considered is the case where the leads are connected along the whole length of the oscillator lattice; that is, in the absence of the ballistic spacer. Upon variation of the system's parameters it was determined that the performance of the device, as quantified by the spectral properties, is largely enhanced in the absence of the ballistic spacer for the small system-size limit herein considered.
