Fig. 2: Quasiparticle interference of two PdGa(001) enantiomers.

From: Handedness-dependent quasiparticle interference in the two enantiomers of the topological chiral semimetal PdGa

Fig. 2

a–h dI/dU maps and relative Fourier transformations obtained on PdGa(001) with opposite bulk chiralities at four representatives energies. Both long A(A’) and short wavelength B(B’) scattering vectors are visible, whose shapes rapidly evolve with energy. Bragg spots (see gray circles) are representatives of the surface square lattice. As highlighted in panels i and j, the scattering vectors are chiral. The scalebar corresponds to 10 nm for dI/dU maps and π/a for Fourier transformations, with a being the lattice constant.
