Calculated spin interactions and percolation theory predict transition temperatures larger than measured, consistent with the observed suppression of magnetically active Mn atoms and hole concentration.Expand

It is demonstrated that vdWH of MoSe2/WSe2 and MoS2/WS2 at twist angles ≤ 1° undergo significant atomic level reconstruction leading to discrete commensurate domains divided by narrow domain walls, rather than a smoothly varying rigid-lattice moiré pattern as has been assumed in prior experimental work.Expand

This work is able to clearly resolve two distinct emission peaks separated by 24 meV from an ILE in a MoSe2/WSe2 heterostructure fabricated using state-of-the-art preparation techniques, representing a significant advance in the understanding of the static and dynamic properties of TMD heterostructures.Expand

Strontium titanate (SrTiO3) is the first and best known superconducting semiconductor. It exhibits an extremely low carrier density threshold for superconductivity, and possesses a phase diagram… Expand

Arrays of quantum dots can be useful for building ‘artificial molecules’, and potentially as elements of quantum information networks. But in practice, no two dots are the same. An optical technique… Expand

Photoluminescence studies of the molecular neutral biexciton-exciton spectra of individual vertically stacked InAs/GaAs quantum dot pairs are presented and either the hole or the electron levels of the two dots are tuned into tunneling resonances.Expand

The recent discovery of superconductivity at 190~K in highly compressed H$_{2}$S is spectacular not only because it sets a record high critical temperature, but because it does so in a material that… Expand

We calculate the structural, electronic, and magnetic properties of MnO from first principles, using the full-potential linearized augmented planewave method, with both local-density and… Expand
