Stability range of parameters at fixed points for a class of complex dynamics
We study the parameters range for the fixed point of a class of complex
dynamics with the rational fractional function as
, where is specified, and
are two complex parameters. The relationship between two parameters, and
, is obtained at the fixed point. Moreover the explicit expression of the
parameter and in terms of is derived, where is the
derivative function at fixed point. The parameter regimes for the stability of
the fixed point are presented numerically for some typical different cases.Comment: 15 pages, 6 figure

N-[2-(2-Chlorophenyl)-2-hydroxyethyl]propan-2-aminium chloride
In the title compound, C11H17ClNO+·Cl−, the side chain of the ethylamine group is orientated approximately perpendicular to the benzene ring, the dihedral angle between the C/C/N plane of the ethylamine group and the benzene plane being 83.5 (3)°. In the crystal structure, intermolecular O—H⋯Cl and N—H⋯Cl hydrogen bonds are observed. The crystal studied was an inversion twin with a 0.51 (10):0.49 (10) domain ratio
Investigation of ultra-thin Al₂O₃ film as Cu diffusion barrier on low-k (k=2.5) dielectrics
Ultrathin Al(2)O(3) films were deposited by PEALD as Cu diffusion barrier on low-k (k=2.5) material. The thermal stability and electrical properties of the Cu/low k system with Al(2)O(3) layers with different thickness were studied after annealing. The AES, TEM and EDX results revealed that the ultrathin Al(2)O(3) films are thermally stable and have excellent Cu diffusion barrier performance. The electrical measurements of dielectric breakdown and TDDB tests further confirmed that the ultrathin Al(2)O(3) film is a potential Cu diffusion barrier in the Cu/low-k interconnects system
