Charge carrier density hall effect formula

WebHall measurements on SiOC/C samples above the percolation threshold indicate p-type carriers mainly contributing to conduction. Their density is shown to vary with the sp 2 carbon content in the range from 10 14 to 10 19 cm −3; whereas their mobility (ca. 3 cm 2 /V) seems to not depend on the sp 2 carbon content.
