Flat electronic band
WebMar 8, 2024 · Materials with flat electronic bands often exhibit exotic quantum phenomena owing to strong correlations. An isolated low-energy flat band can be induced in bilayer graphene by simply rotating the layers by 1.1°, resulting in the appearance of gate-tunable superconducting and correlated insulating phases. WebWe demonstrate, by explicit construction, that a single band tight binding Hamiltonian defined on a class of deterministic fractals of the Sierpinski type can give rise to an infinity of dispersionless, flat-band like…

WebThe doping is controlled by Eu positioning, allowing for the formation of a K-valley localized single spin-polarized low-dispersive parabolic band close to Fermi energy when Eu is on top and a π* flat band with single spin character when Eu is intercalated underneath graphene. In the latter case, Eu also induces a bandgap opening at the Dirac ... WebIn our research we explore in particular the effect of flat bands on the many- body physics. Flat bands, are systems where the energy does not depend on momentum at all. For these special cases, nothing is the way we expect: Bosons don't condense, Fermions don't form a reasonable Fermi- surface and hence ...

WebMar 26, 2024 · A basic idea is that flat bands, arising from quantum mechanical interference, give unique opportunities for enhancing TC with (i) many pair-scattering channels between the dispersive and flat bands, and (ii) an even more interesting situation when the flat band is topological and highly entangled.
WebAfter the preparation of two-dimensional (2D) electronic flat band (EFB) in van der Waals (vdW) superlattices, recent measurements suggested the existence of one-dimensional (1D) electronic flat bands (1D-EFBs) in twisted vdW bilayers. However, realisation of 1D-EFBs has been experimentally elusive in untwisted 2D layers, which is desired ... huggy barbara corcoranWebA non-zero energy band gap between conduction and valence electronic bands is obtained for surfaces with positive curvature.

The DOS (right) is the density of the lines of the band structure for a specific energy. So there's no line that pass through -1 so there's no DOS there. At -0.5, there a almost flat line. On the dos, you can see a clear spike at that value.
