ABSTRACT
Deep centers induced by hydrostatic pressure in GaAs:Si have been studied by deep level transient spectroscopy and constant temperature capacitance transient techniques. The capture behavior of these centers has been studied in detail and found to be consistent with the multiphonon emission theory. The pressure coefficients of the ionization energy and the barrier height are consistent with the large lattice relaxation model proposed by D. V. Lang and R. A. Logan [Phys. Rev. Lett. 39, 635 (1977)].

    A study is undertaken into the kinetics of phase transitions in solids under a load at a fixed temperature. The critical size of the micropores forming at a given load in the course of a phase transition in a material is found. The steady-state flux of pores in size space and the time required...
