Dear MEMS-Colleagues, I am looking for n-type wafers (1 Ohmcm) with excellent minority carrier diffusion length or lifetime. I want to do some electrochemical experiments, where I need to illuminate the sample from the back-side. The photo-generated holes at the back-side must have a sufficient chance to reach the wafer front- side. Does anybody know a wafer vender, how can provide n-type wafers with a specified minority carrier diffusion length also for a low quantity? Thank you and with best regards Marc Marc Christophersen, PhD University of Rochester 601 Elmwood Ave, Box CFH Rochester, NY 14642 ______________________________________________________________________________ ASCII-Bilder und SMS-Sprueche bei WEB.DE FreeMail - auswaehlen, einfuegen und versenden! http://freemail.web.de/features/?mc=021168
