Review of phonons in moiré superlattices

Abstract: Moiré patterns in physics are interference fringes produced when a periodic template is stacked on another similar one with different displacement and twist angles. The phonon in two-dimensional (2D) material affected by moiré patterns in the lattice shows various novel physical phenomena, such as frequency shift, different linewidth, and mediation to the superconductivity. This review gives a brief overview of phonons in 2D moiré superlattice. First, we introduce the theory of the moiré phonon modes based on … Show more

“…This suggests that they are zone-folded phonons due to the moiré superlattice. In homo-TBLs composed of MoS 2 or WSe 2 , ,, the evolution of the zone-folded phonon peaks has been carefully analyzed. However, in hetero-TBLs, such analysis is lacking except for the observation of a few zone-folded moiré phonons for a few twist angles .…”

“…The new nanophotonics methods provide a lot of new opportunities for high‐efficiency, durable, low‐risk and sustainable PSCs. However, more efforts should be invested toward the large‐scale processes to solve the commercialization challenges of PSCs, e.g., 1) higher efficiency and stability against moisture, air, heat and light with the assistance of novel nanophotonics designs; 2) optimization of plasmonic nanostructures as the key roles in ETL, HTL, perovskite layer as well as grating electrode for hot‐carrier generation, local heating and photon cycling to further enhance the efficiency and stability; [ 206 ] reasonable nanophotonics design, such as Si/perovskite tandem SCs, [ 207 ] to harvest more photons and reduce thermalization loss to boost the efficiency; 4) developing high‐performance radiative cooler with high transmission in solar spectrum range and high emission in atmospheric window to cool the temperature, and thus to extend the long‐term operational lifetime; and 5) integrating the both advantages of semi‐transparent PSCs and the thermochromic glass to realize smart windows for energy‐saving buildings.…”

“…Modulations and new periodicities introduced to artificial superlattices can also be engineered to advantageously modify electronic properties and material behavior [1][2][3]. More recent styles of superlattices, such as Moiré-like [4][5][6][7][8] and ordered arrays of nanocrystals [9][10][11], have also been experimentally fabricated and/or used conceptually to explain the observed electronic phenomena [12].…”
