Short summary
We report the effect of surface charge on heterogeneous immersion freezing for the atmospherically relevant sapphire surface. Combining linear and nonlinear optical techniques and investigating isolated drops, we find that charge-induced surface templating is detrimental for ice nucleation on α-alumina surface. This study provides new insights into atmospheric processes and can impact various industrial and research branches, particularly climate change and tracing of water in the hydrosphere.
