Standardized Lifetime Risk [PDF]

open access: yesAmerican Journal of Epidemiology, 1999
The authors propose the use of two new standardized measures of risk, the standardized lifetime risk and the standardized number of years of life lost. These measures maintain the advantages of standardized rates but are more readily understood without special training.

Carrier lifetimes in ion-damaged GaAs [PDF]

open access: yes, 1989
Photoluminescence excitation correlation spectroscopy has been used to measure the dependence of carrier lifetime on the H+ ion implantation dose in GaAs. For doses greater than 1×10^12 cm^−2 the carrier lifetime is inversely proportional to the ion dose.
