Hi MEMS, May I know will there be a big different in the Transverse and longitudinal piezo-resistive coefficient between polysilicon and silicon. If lets say I am using polysilicon for my sensor, can I use silicon as my material properity for my simulation?? And :- n-type silicon:- resistivity = 11.7 (ohm cm) p11 = -102.2 p12 = 53.4 p44 = -13.6 P-type silicon:- resistivity = 7.8 (ohm cm) p11 = 6.6 p12 =-1.1 p44 = +138.1 Best regard AJ Pang -----Original Message----- From: fabounp@yahoo.comTo: MEMS@ISI.EDU Date: 15 March 1999 04:16 Subject: Polysilicon - piezoresistive coefficients >I'm looking for the transverse and the longitudinal piezoresistive >coefficients in the case using polysilicon thin film ....
