Hallo, I am building a silicon pressure sensor and the sensing mechanism is the use of piezoresistors. Is there any equation to determine how much doping of boron i need to create a piezoresistor of a certain piezoresistive coeeficient. If not is there a standard doping concentration for piezoresistors. Thanks Finn Yahoo! Mail : votre e-mail personnel et gratuit qui vous suit partout ! Créez votre Yahoo!
