Stacking numbers for eternal domination

Journal of Combinatorial Mathematics and Combinatorial Computing
In this paper we study a new graph parameter, the stacking number. Defined in relation to the eternal domination game, we show that there are highly connected graphs for which it is beneficial to allow multiple guards to occupy a vertex, answering an open question of Finbow et al.

Stacking number dependence of size distribution of vertically stacked InAs/GaAs quantum dots

Journal of Electronic Materials, 1999
Vertically stacked layer structure is useful for controlling the size distribution of quantum dots. The dependence of the size distribution of quantum dots on the stacking numbers is theoretically and experimentally investigated. We show that the size distribution of quantum dots decreases with increasing the stacking number, and it occurs drastically ...

Magnetoresistance Properties of Cu/Co/Cu/NiFe Multilayers with a Few Stacking Numbers

Japanese Journal of Applied Physics, 1995
[Cu/Co/Cu/NiFe] N multilayers were prepared using electron-beam evaporation in an ultrahigh vacuum and their magnetoresistive (MR) properties with a few stacking numbers (N) were studied.

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 µm by multiple stacked dash layers from two to five, with ground state lasing at room temperature.

Dependence of the Exchange Bias and Coercivity of [Pd/Ferromagnet]$_N$/FeMn Multilayers on the Stack Number$N$

IEEE Transactions on Magnetics, 2006
The dependencies of the stack number N on perpendicular exchange-biasing (Hex) and coercivity Hc) in [Pd/Co]N and [Pd/Co (or CoFe)]N/FeMn multilayers were investigated. With the help of the careful designs of layer structures, a series of samples whose surface anisotropies have the linear function N was prepared with constant bulk anisotropies.

Effect of stack number on the threshold current density and emission wavelength in quantum dash/dot lasers

physica status solidi c, 2009
AbstractInAs quantum dash and dot (QDH and QD) lasers grown by molecular beam epitaxy on InP substrate are studied. The grown lasers with active zone containing multiple stacked layers exhibit lasing wavelength at 1.55 μm. On these devices, the experimental threshold current density reaches its minimum value for a double stacked QDH/QD structure. Other

Electronic and transport properties for Ti3C2O2 under the influence of a vertical electric field and stacking number

Computational Materials Science, 2018
Abstract The effect of a vertical electric field on the structural, electronic, and transport properties of Ti3C2O2 with varying numbers of layers was systematically investigated by means of the first-principles method. This result demonstrated that the related properties of Ti3C2O2 could be effectively tuned by the stacking number and the vertical ...

Observation of the intrinsic Gilbert damping constant in Co/Ni multilayers independent of the stack number with perpendicular anisotropy

Applied Physics Letters, 2013
We investigate the intrinsic Gilbert damping constant in perpendicular magnetic anisotropy Co/Ni multilayer system by means of an all-optical method. We find that the intrinsic Gilbert damping constant does not depend on the stack number and the perpendicular magnetic anisotropy when the magnetic field is high enough. In contrast, the extrinsic Gilbert

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 ...
