Control of adsorbates and conduction on CVD-grown diamond surface, using scanning probe microscopeq

Nanofabrication on a hydrogen-terminated diamond surface is performed by controlling surface adsorbates, using a scanning probe microscope SPM.technique. Insulated areas are successfully obtained by changing hydrogen termination to oxygen termination. The Auger electron spectrum AES.indicated the presence of oxygen adsorbed on the modified surface area. A small isolated conductive area is fabricated, and using this structure, a metal–insulator–metal MIM.diode-like I–V characteristic is observed. Anodic oxidation using the surface water is also suggested for our experimental results. q2000 Elsevier Science B.V. All rights reserved
