Threshold current density and emitting wavelength evolution with stack number in InAs quantum dash lasers at 1.55 μm

2008 20th International Conference on Indium Phosphide and Related Materials, 2008
The authors demonstrate the achievement of InAs quantum dash lasers grown by molecular beam epitaxy (MBE) on InP (100) substrate. The lasers exhibit lasing wavelength at 1.55 mum by multiple stacked dash layers from two to five, with ground state lasing at room temperature.

Hydrodearomatization of petroleum fuel fractions on silica supported Ni–W sulphide with increased stacking number of the WS2 phase⋆

Fuel, 2003
Abstract Ni–W catalysts supported on commercial γ-alumina and silica displayed similar activity in dibenzothiophene hydrodesulfurization (DBT HDS), while the activity of the Ni–W/SiO2 catalyst in toluene hydrogenation (HYD) was 6 times higher compared with Ni–W/Al2O3.

Minimal effect of stacking number on intrinsic cleavage and shear behavior of Tin+1AlCn and Tan+1AlCn MAX phases

Journal of Applied Physics, 2018
MAX phases are layered carbides or nitrides with the general formula Mn+1AXn, which exhibit a unique combination of ceramic- and metal-like properties. The effect of stacking a number (determined by n) remains to be elucidated and a priori is not clear whether, for a given chemistry, n significantly changes the intrinsic deformation behavior of these ...

Numerical Investigation of Natural Convection Heat Transfer From a Stack of Horizontal Cylinders

Journal of heat transfer, 2018
Natural convection heat transfer from horizontal solid cylinders has been studied numerically by varying the Rayleigh number in the range of (104≤Ra≤108) and (1010≤Ra≤1013) for both laminar and turbulent flows, respectively. The computations were carried

Stack Design and Operation for Scaling Up the Capacity of Flow-Electrode Capacitive Deionization Technology

, 2016
Flow electrodes have recently been studied for use in capacitive deionization applications because of their continuous and high desalting efficiency. The production capacity of desalinated water in the flow-electrode capacitive deionization (FCDI) system

Fabrication and applications of multi-layer graphene stack on transparent polymer

, 2017
In this report, we demonstrate the preparation method of a multi-layer stack with a pre-defined number of graphene layers, which was obtained using chemical vapor deposition graphene deposited on a copper substrate and subsequently transferred onto a ...
