Due to its wide band gap and high carrier mobility, ZnO is, among other transparent conductive oxides, an attractive material for light-harvesting and optoelectronic applications. Its functional efficiency, however, is strongly affected by defect-rel

We report on controllable tuning of intersubband transitions in ZnO/Zn0.60Mg0.40O multiple quantum well structures grown by molecular beam epitaxy on sapphire. The transitions from the first to the second electronic energy state within the conduction

Optical second harmonic generation (SHG) on excitons is studied in polar ZnO/(Zn,Mg)O quantum wells grown on ZnO and sapphire substrates. We observe SHG signal on exciton resonances in a symmetry-forbidden geometry for light propagation along the $c$

We demonstrate experimentally and computationally an intricate cavity size dependence of the anomalous near-infrared mode spectrum of an ordinary optical resonator that is combined with a ZnO:Ga-based hyperbolic metamaterial (HMM). Specifically, we r

Monolayer ML transition metal dichalcogenides TMDCs are an attracting new class of two dimensional direct band gap semiconducting materials for optoelectronic device applications. The combination of TMDCs with organic semiconductors holds the promise

Hybrid charge transfer states (HCTS) have been shown to form at interfaces between ZnMgO and P3HT. Combined analysis of the electronic structure of ZnMgO/P3HT interfaces and the corresponding photovoltaic performance, also as a function of temperatur

The deposition of strong molecular electron acceptors onto ZnO induces a substantial work function (\ensuremath{\phi}) increase due to electron transfer from the inorganic semiconductor to the molecules. The \ensuremath{\phi} increase results from tw
