Solute transport mechanism during liquid phase epitaxial (LPE) growth with an applied current

We studied the mechanism of the acceleration of solute transport by passing an electric current through a solution during LPE. We measured the amount of InP dissolved in the solution while a current was applied. The current's magnitude and frequency were varied and the heater current's waveform was changed. We found that the solute dissolved faster when the combination of the solution current and the heater coil current was either 50 Hz AC/50 Hz AC or DC/DC pulse. This indicates that the solute movement is affected by the Lorentz force generated by the current passing through the solution and the magnetic field produced in the heater coil. We concluded that the accelerated dissolution of InP is attributed to the dynamic movement of solution by the Lorentz effect.
