adventitious carbon [9] and nickel oxidation due to pinholes in the gold, the surface of gold will not change with time. The thickness of indium oxide (In2O3) follows a parabolic growth curve [10]. As a solid the growth rate is minimal. A sample in air at 145°C

doesn’t adhere properly to the metal surfaces. In other words, the solder does not "wet" the metal surfaces as it should. This can be caused by several factors that include oxidation, contamination by dirt or grease, or high surface tension
