We examine the surface passivation properties of Al₂O₃ deposited on boron-doped planar <100> crystalline silicon surfaces as a function of the boron concentration. Both uniformly doped and diffused surfaces are studied, with surface boron concentrations ranging from 9.2 × 10¹⁵ to 5.2 × 10¹⁹ cm⁻³. Atmospheric pressure chemical vapor deposition and thermal atomic layer deposition are used to deposit the Al₂O₃ films. The surface recombination rate of each sample is determined from...[Show more]
