RT Journal Article T1 Titanium doped silicon layers with very high concentration A1 Martil De La Plaza, Ignacio A1 González Díaz, Germán A1 Olea Ariza, Javier AB Ion implantation of Ti into Si at high doses has been performed. After laser annealing the maximum average of substitutional Ti atoms is about 10(18) cm(-3). Hall effect measurements show n-type samples with mobility values of about 400 cm(2)/V s at room temperature. These results clearly indicate that Ti solid solubility limit in Si has been exceeded by far without the formation of a titanium silicide layer. This is a promising result toward obtaining of an intermediate band into Si that allows the design of a new generation of high efficiency solar cell using Ti implanted Si wafers.
