Understanding Electronic Peculiarities in Tetragonal FeSe as Local Structural Symmetry Breaking
Zhi Wang, Xingang Zhao, Robert Koch +2
Traditional band theory of perfect crystalline solids often uses as input the structure deduced from diffraction experiments; when modeled by the minimal unit cell this often produ…
Disorder-Induced Weyl Semimetal Phase and Sequential Band Inversions in PbSe-SnSe Alloys
Zhi Wang, Qihang Liu, Alex Zunger
The search for topological systems has recently broadened to include random substitutional alloys, which lack the specific crystalline symmetries that protect topological phases, r…
Experimental imaging and atomistic modeling of electron and hole quasiparticle wave functions in InAs/GaAs quantum dots
G. Bester, D. Reuter, L. He +7
We present experimental magnetotunneling results and atomistic pseudopotential calculations of quasiparticle electron and hole wave functions of self-assembled InAs/GaAs quantum do…
Optical spectroscopy of single quantum dots at tunable positive, neutral and negative charge states
D. V. Regelman, E. Dekel, D. Gershoni +6
We report on the observation of photoluminescence from positive, neutral and negative charge states of single semiconductor quantum dots. For this purpose we designed a structure e…
Localization and band-gap pinning in semiconductor superlattices with layer-thickness fluctuations
K. A. Mader, A. Zunger
We consider (AlAs)_n/(GaAs)_n superlattices with random thickness fluctuations Delta-n around the nominal period n. Using three-dimensional pseudopotential plane-wave band theory,…
Spin-polarization-induced structural selectivity in Pd and Pt () compounds
Z. W. Lu, B. M. Klein, A. Zunger
Spin-polarization is known to lead to important {\it magnetic} and {\it optical} effects in open-shell atoms and elemental solids, but has rarely been implicated in controlling {\i…
