Figure 1. Nitrogen Gun drying substrate

Today our group made the final preparations before actually growing the ferric oxide film onto the substrate.

First, our group took the substrates out of storage and, using a nitrogen gun in Figure 1, dried off the substrates and eliminated the ethanol it had been stored in. 

After the substrates had been dried, they were dip-coated in a solution of Titanium Dioxide (TiO2) in the machine shown in figure 2, to produce a thin film on the substrate. A calculated dip time span of 17 seconds was implemented for the coating of the substrate in order to get an ideal thickness of the film.

The substrates were dried, conductive side up, for approximately 30 minutes. Then the conclusion of our lab came after cleaning the equipment we'd used and throwing into the furnace at 450 degrees Fahrenheit for an hour.
