Triangular potential effects on the fermi velocity renormalization in 8-Pmmn borophene

Abstract

A novel mechanism has been reported for the intrinsic electronic properties of the 8-Pmmnborophene to investigate the electronic energy spectrum and spectrum parameters of thestructure. To examine the structure, we extract the energy spectrum of the Hamiltonianfor the monolayer borophene by using analytical method. Additionally, for the intrinsicproperties, first we obtained the bare Fermi velocity which findings of the study are consistent with experimental results. After obtained the bare state Fermi velocity 8-Pmmnborophene, dressed with triangular potential and renormalized Fermi velocity has beenobtained. Corresponding renormalized Fermi velocity reshaped with the triangular potential which has non-negligible contribution to the intrinsic properties of borophene. Thisfinding has important implications for developing electronic devices which made from theboron due to increasing the controllability of the structure.
