Experimental electronic structure of the mineral superconductor covellite CuS

Alexandre Antezak, Takemi Kato, Pedro Rezende Gonçalves +5

Covellite (CuS) is the first known natural mineral superconductor. Despite its simple chemical formula, covellite exhibits a rich crystal structure at the origin of several remarka…

Dipolar excitonic quantum wires at atomically sharp lateral interfaces

Elie Vandoolaeghe, Francesco Fortuna, Suman Kumar Chakraborty +6

One-dimensional (1D) quantum systems are a cornerstone of many-body physics. However, their realization in solids has traditionally relied on top-down methods, which are limited by…

Dimensional control of the band-gap crossover in layered lead iodide

M. Rosmus, A. Antezak, A. Ptok +11

Before assessing the suitability of a semiconductor for specific applications, the first question to ask is whether it possesses a direct or indirect band gap. This distinction is…

Electronic structure dimensionality of the quantum-critical ferromagnet YbNiP

J. Dai, A. Antezak, W. Broad +15

YbNiP is the first known ferromagnetic metal showing a second-order quantum phase transition. Current theoretical understanding rules out second order ferromagnetic quantum…

Quantum interference effects of out-of-plane confinement on two-dimensional electron systems in oxides

A. F. Santander-Syro, J. Dai, T. C. Rödel +4

It was recently discovered that a conductive, metallic state is formed on the surface of some insulating oxides. Firstly observed on SrTiO(001), it was then found in other comp…

High-density two-dimensional electron system induced by oxygen vacancies in ZnO

T. C. Rödel, J. Dai, F. Fortuna +10

We realize a two-dimensional electron system (2DES) in ZnO by simply depositing pure aluminum on its surface in ultra-high vacuum, and characterize its electronic structure using a…
