Optimization of internal quantum efficiency (IQE) for InGaN quantum wells (QWs) light-
emitting diodes (LEDs) is investigated. Staggered InGaN QWs with large electron-hole …

Vertical composition gradients of ternary alloy thin films find applications in numerous device
structures. Up to now such gradients along the growth direction have not been realized by …

Molecular beam epitaxy (MBE) was adopted to grow zinc oxide (ZnO) film on sapphire
substrate and improve the quality of ZnO thin film epitaxy using a magnesium oxide (MgO) …

Arrays of vertically aligned ZnO: Cl/ZnO core-shell nanowires were used to demonstrate that
the control of the coaxial doping profile in homojunction nanostructures can improve their …

The growth of single and multiple (three) ZnO/ZnMgO quantum well samples on sapphire
substrates, through a two-step temperature variation growth of ZnO buffer layers by …

We report on the high mobility wide electron slabs with enhanced correlation effects by
tailoring the polarization effects in a functionally graded ZnMgO/ZnO heterostructures. The …

Because of the potentially large number of important applications of nonlinear optics,
researchers have expended a great deal of effort to optimize the second-order molecular …

We report tetrapod-like indium-doped ZnO nanorods with a layer-structured surface,
synthesized by a thermal vapor transport method. The high crystalline quality of the …

This work focuses on understanding the nonlinear-optical response of a 1-D quantum wire
embedded in 2-D space when quantum-size effects in the transverse direction are …

Binding energy of an exciton in a wurtzite ZnO/Zn 1− x Mg x O strained quantum well is
investigated theoretically in which the strong built-in electric field due to the spontaneous …
