Scanning Electrode Quartz Crystal Analysis

摘要

Principles and methods for scanning electrode quartz crystal analysis (SEQCA)as a technique for mapping distribution of mass and measuring interfacial theology are described. In SEQCA quartz crystal resonates in a region between a normal electrode and a microelectrode scanned over the opposite side of the normal electrode. The surface of the quartz crystal plate just below the scanning electrode is monitored(overscanning mode).
