CYLINDRICAL PORES IN A GROWING CRYSTAL

The dynamic stability investigation approach is used to analyze the co nditions of elongated pore (negative crystal) formation and steady gro wth. This approach involves the choice of some variable parameters of the analyzed system (in this case, the diameter of pore and the gas co ncentration inside the pore), the formulation of the set of dynamical equations for these variable parameters, the linearization of these eq uations and analysis of stability of the set of equations with respect to Liapunov. The conditions of stable growth of elongated cylindrical pores are determined.
