RT Journal Article T1 Lifetime recovery in ultrahighly titanium-doped silicon for the implementation of an intermediate band material A1 Martil De La Plaza, Ignacio A1 González Díaz, Germán A1 Olea Ariza, Javier AB The doping of conventional semiconductors with deep level (DL) centers has been proposed to synthesize intermediate band materials. A recent fundamental study of the nonradiative recombination (NRR) mechanisms predicts the suppression of the NRR for ultrahigh DL dilutions as a result of the delocalization of the impurity electron wave functions. Carrier lifetime measurements on Si wafers doped with Ti in the 10(20)-10(21) cm(-3) concentration range show an increase in the lifetime, in agreement with the NRR suppression predicted and contrary to the classic understanding of DL action.
