In this work, hafnium oxide (HfO2) thin films are deposited on p-type Si substrates by remote plasma atomic layer deposition at 250 °C, followed a rapid thermal annealing in nitrogen. Effect of post-annealing temperature the crystallization HfO2 and HfO2/Si interfaces is investigated. The interface studied field emission transmission electron microscopy, X-ray photoelectron spectroscopy, diffraction, force microscopy. experimental results show that during annealing, oxygen diffuse from to...
Novel phosphors Na3KMg7(PO4)6: RE3+ (RE = Eu, Dy, Tb) phosphor were successfully synthesized through a high temperature solid-state reaction method. The X-ray diffraction (XRD), scanning electron microscopy (SEM), photoluminescence (PL) excitation and emission spectra, decay lifetimes temperature-dependent PL spectra utilized to characterize these as-synthesized samples. Under suitable UV light excitation, Eu3+, Dy3+, Tb3+ exhibited the characteristic of Eu3+ at 696 nm (the 5D0→7F4...
Although gel chromatography has demonstrated excellent structural separation ability with semiconducting single-wall carbon nanotubes (SWCNTs), of metallic SWCNTs remains a challenge due to their weak interactions dextran-based media. In this work, we report cholate derivative, sodium hyodeoxycholate (SHC), and apply it the SWCNTs. The results demonstrate that adsorbability coated by SHC SDS surfactants on can be dynamically enhanced through addition NaOH, difference in adsorption order...
Halide segregation is a critical bottleneck that hampers the application of mixed-halide perovskite nanocrystals (NCs) in both electroluminescent and down-conversion red-light-emitting diodes. Herein, we report strategy combines precursor surface engineering to obtain pure-red-emitting (peaked at 624 nm) NCs with photoluminescence quantum yield up 92% strongly suppresses halide under light irradiation. Red-light-emitting diodes (LED) using these as phosphors exhibit color-stable emission...
Hafnium oxide (HfO2) thin films have attracted much attention owing to their usefulness in equivalent thickness scaling microelectronics, which arises from high dielectric constant and thermodynamic stability with silicon. However, the surface passivation properties of such films, particularly on crystalline silicon (c-Si), rarely been reported upon. In this study, HfO2 were deposited c-Si substrates without oxygen plasma pretreatments, using a remote atomic layer deposition system....
