Abstract

The surface conductivity of diamond has recently attracted a lot of interest since a number of electronic applications proposed for diamond are based on this effect. Nevertheless, its microscopic origin is still a matter of debate. We describe in the following experiments in which the impact of the balk defect concentration of diamond on the surface conductivity is investigated. The experiments show that surface conductivity is suppressed in the presence of donor-like nitrogen defects although the surfaces are clearly hydrogen (or deuterium) terminated. We suggest compensation of the surface or surface near acceptors to be the reason for this suppression. A quantitative discussion shows that the doping capability of the surface acceptors is exhausted at lateral concentrations of about 3 × 10¹³ cm^-2.
