Morphological stability of GaP(1 1 1)B in LPE under static magnetic field

摘要

The step kinetic coefficient of the GaP/GaP(1 1 1)B surface in liquid-phase epitaxial growth was estimated by means of an in situ observation technique using a near-infrared microscopic interferometer under a static magnetic field of 4 T. Morphological stability of the solid/liquid interface during the growth was evaluated based on a linear perturbational approach taking into account the step kinetic coefficient. The estimated value of the macrostep wavelength agreed well with the measured one.
