Ml. Saenz et Jmg. Perez, EVIDENCE OF INTERNAL PHOTOEMISSION IN THE CO2-LASER-INDUCED NEGATIVE POTENTIAL IN HOMOJUNCTIONS, Physical review. B, Condensed matter, 52(15), 1995, pp. 11120-11124
A component of the strongly bias-dependent potential in the far-infrar
ed laser-induced photoeffect produced in silicon and germanium homojun
ctions is reported. A model of laser-heated hot-carrier internal photo
emission is presented. The model predictions are compared to experimen
tal results, showing good agreement.
