RF plasma functionalized carbon surfaces for supporting sensor architectures

Abstract

Carbon has a number of properties that make it ideal for use in sensor and electrical applications. Using radio frequency plasma with different precursor gases and operating plasma conditions, it is possible to pre-treat a variety of carbon surfaces in preparation for further molecular attachment, or surface functionalization. Research in our laboratory involves studies on highly ordered pyrolytic graphite (HOPG) as a model carbon substrate and pyrolysed photoresist films (PPF). Plasma treated surfaces have been characterised using a variety of surface sensitive techniques. We will report on results obtained using X-ray photoelectron spectroscopy to probe the chemical nature of the treated s..
