Single-crystalline hexagonal ZnO microtube optical resonators

Single-crystalline ZnO sheet Source-Gated Transistors

Due to their fabrication simplicity, fully compatible with low-cost large-area device assembly strategies, source-gated transistors (SGTs) have received significant research attention in the area of high-performance electronics over large area low-cost substrates. While usually based on either amorphous or polycrystalline silicon (α-Si and poly-Si, respectively) thin-film technologies, the pres...

Waveguide-integrated single-crystalline GaP resonators on diamond.

Large-scale entanglement of nitrogen-vacancy (NV) centers in diamond will require integration of NV centers with optical networks. Toward this goal, we present the fabrication of single-crystalline gallium phosphide (GaP) resonator-waveguide coupled structures on diamond. We demonstrate coupling between 1 μm diameter GaP disk resonators and waveguides with a loaded Q factor of 3,800, and evalua...

Excitonic fine structure and recombination dynamics in single-crystalline ZnO

Aqueous Epitaxial Growth of ZnO on Single Crystalline Au Microplates

Epitaxial ZnO thin films were grown on single crystalline Au microplates from an aqueous solution at 90 °C. The composite structures were approximately 100 μm wide. The epitaxial ZnO films were smooth, continuous, and several micrometers thick. We examined the epitaxial relationship between the ZnO and Au through scanning electron microscopy, electron backscatter diffraction, high-resolution tr...
