Abstract
This paper describes variations in current density observed in linear sweep voltammetry curves during the anodization of n-InP in aqueous KOH electrolyte and how these variations arise. The analysis is performed by stopping the anodization after different durations of etching and observing via scanning electron microscopy and other techniques the porous structures that have formed. A mathematical model for the expansion and merging of domains of pores that propagate preferentially along the <111>A directions is also presented and used to explain the previously mentioned variations in current density.
