Abstract

Surface composition changes at the surface of chemical vapor deposited diamond samples are reported after immersion in an aqueous phosphate buffer solution and exposure to 24 kHz power ultrasound (30 W cm-2). Based on X-ray photoelectron spectroscopy data it is demonstrated that heterogeneous sonochemical processes give rise to surface functionalization of diamond surfaces and that the type of gas present during the treatment has a strong effect on the interfacial process.
