Auxetic properties of polycrystals
Cz. Jasiukiewicz, T. Paszkiewicz, S. Wolski
Young's and shear moduli and Poisson's ratio of polycrystalline solids consisting of 2D quadratic and 3D cubic randomly oriented grains of the same size and shape is studied. Consi…
Elastic properties of cubic crystals: Every's versus Blackman's diagram
T. Paszkiewicz, S. Wolski
Blackman's diagram of two dimensionless ratios of elastic constants is frequently used to correlate elastic properties of cubic crystals with interatomic bondings. Every's diagram…
On the upper limit of thermal conductivity GaN crystals
B. A. Danilchenko, I. A. Obukhov, T. Paszkiewicz +2
The maximal value of thermal conductivity κ_{max} of the perfect wurzite GaN crystal containing isotopes of natural abundance is estimated. Our upper limit of κ=4800 W/Km at T_{max…
Fourth-rank tensors of Voigt's symmetry and elastic material constants for all systems of 2D crystals
Cz. Jasiukiewicz, T. Paszkiewicz, S. Wolski
Fourth-rank tensors of complete Voigt's symmetry, that embody the elastic properties of crystalline anisotropic substances, were constructed for all 2D crystal systems. Using them…
Auxetic properties and anisotropy of elastic material constants of 2D crystalline media
Cz. Jasiukiewicz, T. Paszkiewicz, S. Wolski
Anisotropies of Young's modulus E, the shear modulus G, and Poisson's ratio of all 2D symmetry systems are studied. Simple necessary and sufficient conditions on their elastic comp…
Heat capacity and phonon mean free path of wurtzite GaN
B. A. Danilchenko, T. Paszkiewicz, S. Wolski +2
We report on lattice specific heat of bulk hexagonal GaN measured by the heat flow method in the temperature range 20-300 K and by the adiabatic method in the range 5-70 K. We fit…
