November+9-10

November 9th:

-Scanning new sample -Au(III) exposed to beat sample for 4 hours -cut new PtIr tip before starting scan

-11-9-11AA -approach settings: -1.5 nA -10000 p-gain -1000 i-gain -50mV tip voltage

-it took about 2 minutes to approach the tip

-11-9-11AB -approach settings: -1.5 nA -10000 p-gain -1000 i-gain -50mV tip voltage



November 10th:

-Scanning same sample as yesterday -Au(III) exposed to beat sample for 4 hours -cut new PtIr tip before starting scan

-the scans stayed pretty consistent and all ended up using the same scan settings

-11-10-11AA -approach settings: -1.5 nA -10000 p-gain -1000 i-gain -50mV tip voltage

-it took about 2 minutes to approach the tip

-11-10-11AB -approach settings: -1.5 nA -10000 p-gain -1000 i-gain -50mV tip voltage

-11-10-11AC -approach settings: -1.5 nA -10000 p-gain -1000 i-gain -50mV tip voltage

-11-10-11AD -approach settings: -1.5 nA -10000 p-gain -1000 i-gain -50mV tip voltage

-11-10-11AE -approach settings: -1.5 nA -10000 p-gain -1000 i-gain -50mV tip voltage

-11-10-11AF -approach settings: -1.5 nA -10000 p-gain -1000 i-gain -50mV tip voltage



The last image in particular (upper right) was interesting. It was the same area as the bottom left but zoomed in. These ridges appeared and I will further investigate what they could be.
