The role of the federal states(Länder)in Germany’s sustainability transformation has received comparatively little attention in the political science literature. This article examines the contributions, capacities and competencies of theLänderin

Abstract The construction of a large-scale quantum internet requires quantum repeaters containing multiple entangled photon sources with identical wavelengths. Semiconductor quantum dots can generate entangled photon pairs deterministically with high

The first part of this work evaluates Al-doped ZnO (AZO) as an optically transparent top-gate material for studies on semiconductor quantum dots. In comparison with conventional Ti gates, samples with AZO gates demonstrate a more than three times hig

The crossover from quasi-two- to quasi-one-dimensional electron transport subject to transverse electric fields and perpendicular magnetic fields is studied in the diffusive to quasi-ballistic and zero-field to quantum Hall regime. In-plane gates and

Strain-free GaAs cone-shell quantum dots have a unique shape, which allows a wide tunability of the charge-carrier probability densities by external electric and magnetic fields. Here, the influence of a lateral electric field on the optical emission

Klimawandel und Klimaschutz sind globale Themen. Folglich, so eine weit verbreitete These, konne auch die Problemlosung nur global sein. Das Weltklima sei nicht alleine dadurch zu retten, dass sich ein Bundesland wie Hessen besonders engagiere. Dafur

The legal and political interrelations between national and EU energy policy competencies and the actual policies are multifaceted. In order to understand those interrelations properly one has to analyse both the formal competencies of the EU as ensh
