Anisotropic stimulated emission from aligned CdSe/CdS dot-in-rods

Gao, Y.; Ta, V. D.; Zhao, X.; Wang, Y.; Chen, R.; Zhao, Y.; Dang, C.; Sun, X.; Sun, H.; Demir, Hilmi Volkan (IEEE, 2014-10)

Anisotropic optical properties of CdSe/CdS dot-in-rods loaded in a capillary tube are demonstrated, suggesting nanorods' alignment with a microfluidic approach. Polarized emissions from photoluminescence and whispering ...

Band alignment issues related to HfO2/SiO2/p-Si gate stacks

Sayan, S.; Emge, T.; Garfunkel, E.; Zhao, X.; Wielunski, L.; Bartynski, R. A.; Vanderbilt, D.; Suehle, J. S.; Süzer, Şefik; Banaszak Holl, M. (American Institute of Physics, 2004-12-15)

The valence and conduction band densities of states for the HfO2/SiO2/Si structure are determined by soft x-ray photoemission and inverse photoemission. First principles calculations are used to help in assigning valence ...

Exciton energy recycling from ZnO defect levels: towards electrically driven hybrid quantum-dot white light-emitting-diodes

Zhao, X.; Liu W.; Chen R.; Gao, Y.; Zhu B.; Demir, Hilmi Volkan; Wang, S.; Sun, H. (Royal Society of Chemistry, 2016)

An electrically driven quantum-dot hybrid white light-emitting diode is fabricated via spin coating CdSe quantum dots onto a GaN/ZnO nanorod matrix. For the first time, quantum dots are excited by fluorescence resonance ...

Manipulating optical properties of ZnO/Ga: ZnO core-shell nanorods via spatially tailoring electronic bandgap

Zhao, X.; Gao, Y.; Wang Y.; Demir, Hilmi Volkan; Wang, S.; Sun, H. (Wiley-VCH Verlag, 2015)

Enhancing optical and electrical properties of ZnO nanostructures via surface doping is demonstrated by Ga:ZnO–ZnO core–shell nanorods, which are grown by a genetic two-step method. Low-temperature photoluminescence and ...

Observation of polarized gain from aligned colloidal nanorods

Gao, Y.; Ta, V. D.; Zhao, X.; Wang Y.; Chen R.; Mutlugün, E.; Fong, K. E.; Tan S.T.; Dang C.; Sun, X. W.; Sun, H.; Demir, Hilmi Volkan (Royal Society of Chemistry, 2015)

In recent years, colloidal semiconductor nanorods have attracted great interest for polarized spontaneous emission. However, their polarized gain has not been possible to achieve so far. In this work we show the highly ...

Solvent-assisted surface engineering for high-performance all-inorganic perovskite nanocrystal light-emitting diodes

Wang, L.; Liu, B.; Zhao, X.; Demir, Hilmi Volkan; Gu, H.; Sun, H. (American Chemical Society, 2018)

All-inorganic cesium halide perovskite nanocrystals have attracted much interest in optoelectronic applications for the sake of the readily adjustable band gaps, high photoluminescence quantum yield, pure color emission, ...

Three channels of monetary policy international transmission: Identifying spillover effects from the US to China

Zhang, M.; Şensoy, Ahmet; Cheng, F.; Zhao, X. (Elsevier Inc., 2022-05-02)

We identify and compare three channels through which the adjustment of US monetary policy spills over into China, including trade, exchange rate, and financial channels. A proxy vector autoregression model, with a ...

Unusual fluorescent properties of stilbene units and cdzns/zns quantum dots nanocomposites: white-light emission in solution versus light-harvesting in films

He T.; Gao, Y.; Gao, y.; Lin, X.; Chen R.; Hu, W.; Zhao, X.; Wang Y.; Demir, Hilmi Volkan; Fan, Q.; Grimsdale, A. C.; Sun, H. (Wiley - V C H Verlag GmbH & Co. KGaA, 2016)

Nanocomposites with organic–inorganic properties represent a new fi eld of basic research and offer prospects for many novel applications in extremely diverse fi elds, due to their remarkable emerging new properties and ...
