Deposited gold layer radius

A schematic of the working electrode configuration is shown in Fig. 12. The radius of the quartz disk, Tq, is 1/2 inch the thickness, dq, is 1/8 inch. A thin layer of titanium ( 5 x 10 cm) is vapor deposited on the quartz disk followed by deposition of the desired thickness, of gold (generally 10 cm where noted 0.3 x 10 " cm). The radius of the deposited gold layer, r, is 1.1 cm the radius of the exposed electrode, /- , is 0.475 cm. Details of the preparation of the gold electrode are presented in Sec. V.B. The entire assembly is held together with a simple clamp (not shown in Fig. 12).

Noticeably, the nanofabrication approach was also successful for the fabrication of the SECM-SICM nanotips based on heat-pulled nanopipettes [144,183,184]. For instance, a heat-pulled nanopipette was coated with gold, insulated by the atomic layer deposition of aluminum oxide, and milled by FIB technology to expose a 100-nm-diameter nanopore next to a gold nanoelectrode with an effective radius of 294 nm (Figure 1.31c) [183], Similarly, an SECM-SICM nanotip was...
