Continuously tunable band gaps of monatomic carbon chains in the visible light region: A first principle study
Studies on infinite long monatomic carbon chains based on the hybrid density functional calculations show that the direct band gap can be continuously tuned from 1.58 to 3.8 eV by stretching the chains up to 10% elongation and pairs of sharp peaks locate at the well separated Van Hove singularities in the density of s…
Probing the local density of states in three dimensions with a scanning single quantum emitter
Their intrinsic properties render single quantum systems as ideal tools for quantum enhanced sensing and microscopy. As an additional benefit, their size is typically on an atomic scale which enables sensing with very high spatial resolution. Here, we report on utilizing a single nitrogen vacancy center in nanodiamond…

CHARACTERIZATION STUDIES OF THE SELECTIVE REDUCTION OF NO by NH3
This report describes a set of experiments which characterize, in part, the selective reduction of NO via NH 3 in the post combustion gases of propane/air in a laboratory scale combustion tunnel.The newly constructed tunnel supports steady state reproducible turbulent combustion under a variety of operating conditions…
Development of output signal-to-noise ratio tester for microchannel plate and fluorescent screen component
The core components of Image intensifier is microchannel plate (MCP) and fluorescent screen component. The present paper deeply studies output signal-to-noise ratio (SNR) characteristics of MCP and fluorescent screen component. A tester system using to the evaluation of characteristics of the output SNR of MCP and flu…
High-quality quantum-dot-based full-color display technology by pulsed spray method
We fabricated the colloidal quantum-dot light-emitting diodes (QDLEDs) with the HfO2/SiO2-distributed Bragg reflector (DBR) structure using a pulsed spray coating method. Moreover, pixelated RGB arrays, 2-in. wafer-scale white light emission, and an integrated small footprint white light device were demonstrated. The…

Kosmische Primärstrahlung besteht zu 99 % aus Kernen der häufigsten Atome (H, He, Fe). Diese Ionen induzieren in biologischen Materialien mehrfache Ionisationen bis hin zur Coulomb-Explosion von Biomolekülen. In ihrer Zuschrift auf S. 3242 ff. untersuchen M.-A. Hervé du Penhoat, M.-F. Politis et al. die Hydroxylierung…
Nonlinear absorption in InN under resonant- and non-resonant excitation
We report the wavelength-dependent nonlinear absorption (NLA) of InN film grown on anr-plane sapphire by molecular beam epitaxy technique. In order to understand the nonlinear optical properties of InN, the Z-scan measurement was performed at two different wavelengths, the photon energies of which are near (resonant…
Indium-zinc oxide transparent electrode for nitride-based light-emitting diodes
The basic properties of indium-zinc oxide (IZO) were investigated from the view point of the potential of light-emitting diodes (LEDs) for nanostructured transparent contact. The resistivity and contact resistance to p-GaN were obtained to be 2.5×10-4 Ωcm and 9.4×10-4 Ωcm2, respectively, which are comparable to those…
Semipolar GaN growth on patterned sapphire substrates by hydride vapor phase epitaxy
This paper presents the growth of thick semipolar {10-11}, {11-22}, and {20-21} GaN layers on n, r, and {22-43} patterned sapphire substrates (PSSs), respectively, by hydride vapor phase epitaxy. The reduction rate of the dislocation density varied with growth planes. For {10-11} GaN layers, the dislocation density dr…
Depth distribution of carrier lifetimes in semipolar (11macron01) GaN grown by MOCVD on patterned Si substrates
Semipolar (11macron01) GaN layers and GaN/InGaN LED structures were grown by metal-organic chemical vapor deposition on patterned (001) Si substrates. Optical properties of the semipolar samples were studied by steady-state and time-resolved photoluminescence (PL). Photon energies and intensities of emission lines fro…
Low resistivity electrical contacting of porous n-type GaN layers due to reduced workfunction intermetallic seed layers
Porous GaN crystals have been grown on Pt- and Au- coated silicon substrates as porous crystals and as porous layers. By the direct reaction of metallic Ga and NH3 gas in a CVD system, intermetallic metal-Ga alloys formed at the interface allow the seeding and growth of porous GaN by vapor-solid-solid processes. Curre…
Detection of alternative conformations:Shift_plotandAC_predictionprograms
Increased mobility of poorly ordered atoms compared to well ordered ones in unrestrained refinement was adopted as the basis for the development of a method for predicting alternative conformations. Two programs for the analysis of atomic mobility are presented.Shift_plotmay be useful for visual analysis of magnitudes…

A scheme for realizing continuously tunable spectrum in the visible light region based on monatomic carbon chains
We propose a scheme for realizing the continuously tunable spectrum based on monatomic carbon chains. By hybrid density functional calculations, we first show that the direct band gap of monatomic carbon chains change continuously from 1.58 to 3.8 eV as strain is applied from -5 to 10% to the chain, with separated Van…
