Some semiconductor questions

hi guys,

i have two semiconductor questions that have been troubling me.

1. can measured carrier lifetimes be used to determine if the material is n-type or p-type?

2. what would be the effect on the lifetime of increasing the sample temperature?

i have been getting mixed information on both questions and was wondering if someone could clear it up for me.

thankyou

Look at Seegers book on Semiconductors, it has the best writeup on relaxation time approximation for electronic transport in semiconductors without getting into the nuances of the advanced formulation. I'll be happy to work with you on this further if youare still confused.

thanks for the tip on the book, unfortunately it was sunday today and the library at my university was closed, i'll have to look it up tomorrow.
