Uncovering the Fourier Structure of Wavefunctions in Semiconductors
Yunfan Liang, Damien West, Shengbai Zhang
Symmetry is at the heart of material properties. Symmetry of the Bravais lattice defines the degeneracy of planewaves, upon which atomic symmetry determines interaction potentials…

Atomic short-range order: a new degree of freedom for band engineering of GeSn semiconductor alloys
Shang Liu, Yunfan Liang, Nirosh M. Eldose +18
Chemical short-range order (SRO) in alloys denotes the statistical preference or avoidance between atomic species on neighboring lattice sites. Here, we highlight SRO as a powerful…
