Mesoporous silicon doped with 3.0 x 10(19) B atoms cm(-3) (p(+)-type) is an insulating material which dramatically increases its electrical conductivity when exposed to traces of gaseous NO(2); nitrogen dioxide chemisorption at the surface generates carriers, the population of which is readily evaluated through the intensity of IR absorption.

Abstract
Mesoporous silicon doped with 3.0 x 10(19) B atoms cm(-3) (p(+)-type) is an insulating material which dramatically increases its electrical conductivity when exposed to traces of gaseous NO(2); nitrogen dioxide chemisorption at the surface generates carriers, the population of which is readily evaluated through the intensity of IR absorption.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
