Trigonal warping graphene
WebIn particular, the electronic Fermi line in each of its valleys has a strong p→-p asymmetry due to trigonal warping, which suppresses the weak localization effect. We show that … WebWe calculate the form of quasiparticle interference patterns in bilayer graphene within a low-energy description, taking into account perturbatively the trigonal warping terms. We introduce four different types of impu…

We present calculations of the … WebHere, we predict that a high-quality graphene bilayer aligned with an hBN substrate features T 2-dependent resistivity caused by umklapp electron-electron (Uee) scattering from the moir'e superlattice, that is, a momentum kick by Bragg scattering experienced by a …
WebAn attempt to represent the transition to the state of excitonic insulator as the appearance of Majorana zero-modes solution in graphene with trigonal warping contradicts experimental data on the absence of a gap in band structure of graphene and on diminishing of charged carriers mobility and minimal conductivity . WebThe photoluminescence (PL) of multiwalled carbon nanotubes (MWCNTs) synthesized with ethanol flames was investigated at temperatures from 30 to 300 K. Broad-band PL emission in the near-infrared region was observed at temperatures below 240 K. The PL intensity was abruptly boosted up at 240 K, and then quickly became quenched and undetectable as the …
